Getting race day right

The decisions that are made in the last three weeks and on the morning itself — where most races are won or lost.

How to Pace a Marathon: Even Splits vs Negative Splits The safest way to pace a marathon is with even splits — running each mile within a few seconds of your target average pace throughout — or a mild negative split, where the second half is slightly faster than the first. Starting even or conservative and finishing strong beats starting fast and fading, which is how most marathon 'blow-ups' happen. 7 min read Uses the Pace Calculator Marathon Taper Guide: The Final 2 Weeks A marathon taper means reducing training volume by roughly 40-60% over the final 2-3 weeks before race day, while keeping some intensity, so your body can fully absorb months of training. The biggest taper mistake is treating reduced mileage as an excuse to also stop running altogether — under-tapering and over-tapering both hurt race performance, but doing nothing is worse than doing less. 5 min read Uses the Pace Chart What to Eat Before a Half Marathon or Marathon In the 2-3 days before a half marathon or marathon, gradually increase carbohydrate intake while keeping meals familiar. On race morning, eat a carb-focused, low-fiber, low-fat breakfast 2-3 hours before the start — something you've already tested in training, never something new. 5 min read Uses the Pace Chart How to Fuel a 70.3: Middle-Distance Nutrition Strategy A 70.3 typically demands 60-90 grams of carbohydrate per hour once you're past the first 60-90 minutes, spread across the bike (the easiest leg to fuel) and run (the hardest). Hydration and sodium matter as much as carbohydrate over 5-8 hours — under-fueling and dehydration, not lack of fitness, are the most common reasons athletes fade in the final 10K. 5 min read Uses the Split Calculator

Training properly

How long it takes, what to aim at, and how to set paces that are actually yours rather than copying a plan built for somebody else.

How Long Does It Take to Train for a Marathon? For someone who can already run comfortably for 30 minutes, a marathon takes 16 to 20 weeks of training. From a standing start, allow 9 to 12 months: roughly six months to build to a comfortable 10K and a 20-mile week first, then the 16-to-20-week block on top. The limit is rarely fitness — it is how fast your tendons, bones and joints adapt. 9 min read Uses the Marathon Training What Is a Good Marathon Time? A good marathon time is one that matches what you can already run over shorter distances. Sub-4:00 is the most common first serious target and needs roughly a 1:55 half, a 52:10 10K or a 25:01 5K. Sub-3:30 needs about a 1:40 half, and sub-3:00 about a 1:26 half. If your shorter times are well ahead of those, your marathon target is too soft. 7 min read Uses the Time Predictor How to Break 4 Hours in the Marathon A sub-4:00 marathon means holding 9:09 per mile, or 5:41 per kilometre, for 26.2 miles. It corresponds to roughly a 1:55 half marathon, a 52:10 10K or a 25:01 5K. Reaching it usually needs four to five runs a week for 16 to 20 weeks, most of them genuinely easy at 9:49-11:44 per mile, with weekly threshold work at around 8:33-8:58 per mile. 8 min read Uses the Pace Chart VDOT and Training Paces Explained VDOT is an estimate of your running-specific VO2max, calculated from a recent race result rather than a lab test. It's used to generate five training pace zones — Easy, Marathon, Threshold, Interval and Repetition — so that a single number can tell you exactly how fast to run on any given training day, not just on race day. 5 min read Uses the Training Paces How Hot Is Too Hot to Run? Add air temperature and dew point together in Fahrenheit. Under 100 there is no real penalty. 120-130 costs 1-2% of your pace, 140-150 costs 3-4.5%, and above 165 the honest answer stops being a percentage and becomes whether to run at all. Air temperature alone is a poor guide: 32°C with a 10°C dew point scores 140, while 32°C with a 22°C dew point scores 161. 9 min read Uses the Heat Pace

Choosing a race, and getting into it

Which race, in which season, with a cut-off you can actually make — and how to get a place in the ones that sell out.

How to Choose Your First Marathon For a first marathon, the cut-off time matters more than the course profile. UK cut-offs range from six hours at Manchester, Chester and Abingdon to eight at London — if you expect to take more than five and a half, that difference decides your shortlist before anything else does. Then pick a season: spring races mean winter training, autumn races mean summer long runs. 9 min read Uses the Time Predictor How to Get a London Marathon Place Five routes into the London Marathon: the public ballot, a charity place, Good For Age, Championship entry, or a club place. The ballot is free but 1.33 million applied for the 2026 race. Good For Age needed sub 2:52 for men and sub 3:38 for women at 18-39; Championship needs sub 2:38 or sub 3:10. 12 min read Uses the Time Predictor From parkrun to Your First 10K If you can finish a parkrun, you can finish a 10K — the gap is smaller than it looks. A 30-minute parkrun predicts roughly a 1:02:33 10K and a 25-minute parkrun a 52:07. Eight weeks is usually enough to bridge it: keep parkrun as your weekly hard effort, add one longer run building to 8-9km, and add one steady midweek run. 8 min read Uses the Time Predictor Your First Ultra Marathon: How to Choose One and Finish It Start at 50K. It is the shortest ultra distance, it is only about five miles beyond a marathon, and typical cut-offs of nine to ten hours make it a genuinely forgiving first attempt. The three things that change from road marathons are that walking becomes a deliberate strategy, real food replaces gels, and you have to carry your own kit. 10 min read Uses the Pace Calculator

Your first triathlon

The three things that catch every first-timer: which distance to enter, the swim, and transition.

How to Choose Your First Triathlon Distance Most first-time triathletes should start with Sprint distance (750m swim / 20km bike / 5km run) — long enough to be a genuine achievement, short enough to be realistic on 8-12 weeks of part-time training. Super Sprint is the safer choice if open-water swimming is your biggest concern; Olympic and beyond are better second- or third-race goals once you've completed one event. 5 min read Uses the Split Calculator Open Water Swimming for Beginners: Triathlon Swim Tips Open water swimming feels harder than pool swimming mainly because of a lack of visual reference (no black line, no wall), cooler water, and close contact with other swimmers — not because it demands more fitness. The single most effective preparation is simply practicing in open water itself, ideally wearing the same wetsuit you'll race in, well before event day. 5 min read Uses the Swim Pace Triathlon Transition Guide: Mastering T1 and T2 T1 is the transition from swim to bike; T2 is bike to run. Both are timed as part of your official race result, so a slow, disorganized transition costs real minutes — often more than most athletes could gain by training harder on any single discipline. A well-practiced transition takes under a minute; most beginners take 2-4 minutes without ever realizing how much time is available for free. 5 min read Uses the Split Calculator Triathlon Wetsuit Rules Explained: When Do You Actually Need One? Under the standard British Triathlon rule, wetsuits are mandatory below 14°C, optional between 14°C and roughly 22-24.6°C (depending on the specific event and category), and banned above that upper threshold. Water temperature is checked on race morning, typically about an hour before the swim, so the exact rule for your event is only confirmed on the day itself. 4 min read Uses the Swim Pace

Running and racing in Britain

What actually shapes a British running year — daylight rather than weather — plus the fells, the national trails, London and how entry really works.

Britain's Real Running Constraint Isn't Rain, It's Daylight London records rain on about 132 days a year and, in eleven years of records, has never averaged a start-line temperature at or above 24°C in any month. Britain is almost never heat-limited or rain-limited. What genuinely constrains running here is daylight: London gets under eight hours at the winter solstice and Edinburgh under seven. 7 min read Uses the Pace Calculator The British Racing Calendar: How the Year Is Actually Shaped The British year has four distinct seasons of racing: cross country and winter ultras from November to February, the spring marathon peak in April, a summer of fell, trail and multi-day racing, and a fast autumn of half marathons in September and October. Almost nothing fast happens in midsummer, and almost nothing long happens in midwinter — except deliberately. 6 min read Uses the Time Predictor How to Enter UK Races: Ballots, Sell-Outs, Affiliation and Good For Age Most British races are first come, first served rather than ballots — the constraint is remembering to enter, not luck. UKA affiliation through a club saves about £2 on most entries. The races that genuinely sell out fast are the ultras: Centurion open entries roughly eleven months ahead and fill in minutes. 6 min read Fell Running and the British Mountains: What Makes It Different Fell running is a distinctly British discipline: unmarked routes across open mountain, navigation as the runner's responsibility, minimal support and no course marking. It is not trail running with hills in it. The steepest race on this site, the Old County Tops, carries 270ft of climb per mile across 37 Lakeland miles. 6 min read Running Britain's National Trails: The Long Paths and the Races on Them Britain's national trails are the backbone of its ultra calendar. The South Downs Way carries Centurion's 50 and 100, the Ridgeway carries Race to the Stones and the 86-mile Ridgeway Challenge, the Cleveland Way carries the whole Hardmoors series, and the Pennine Way carries the Spine. 6 min read Running in London: Parks, Towpaths and the Races London gives you more traffic-free running than almost any capital: eight royal parks, the Thames Path running the width of the city, a canal network you can follow to the M25, and Richmond Park at 2,500 acres. There are 38 races and dozens of parkruns in the city, including the one where parkrun was invented. 5 min read Uses the Pace Calculator Triathlon in Britain: The Water, the Scene and the Races British triathlon has an unusually gentle entry point and an unusually severe top end. Pool-based sprints get beginners in without open water at all, while Helvellyn finishes with a mountain summit and the Brutal climbs Snowdon after a full-distance bike. British water sits around 12-18°C in season, so a wetsuit is near-universal. 5 min read Uses the Split Calculator Running in Britain Region by Region: What Each Part Actually Offers Britain packs more variety into a small island than anywhere in Europe: chalk downland in the South East, coast path in the South West, fells in Cumbria, gritstone in the Peak, mountains in Wales and Scotland, and flat fen in the East. London and the South East carry the densest race calendar; the North West and Wales carry the hardest. 10 min read

Running and racing in Ireland

The wind nobody warns you about, a calendar built around a few very large city races, and all twenty-six counties.

Running in Ireland's Weather: What Eleven Years of Records Actually Show Dublin averages 162 rain days a year against London's 132, but its annual temperature range is only 11°C — from an 8.3°C January high to 19.3°C in July. In eleven years of records no month has averaged a start-line temperature above 24°C. Ireland is wetter than Britain and materially cooler in summer, which makes it one of the easiest places in Europe to race hard. 8 min read Uses the Pace Calculator The Irish Racing Calendar: How a Year Is Actually Structured The Irish racing year runs continuously rather than in a season. It opens with the January and February imperial classics — Raheny 5, Trim 10, Dungarvan 10 — builds through spring half marathons, spreads marathons from Limerick in May to Dublin on the last Monday of October, and never really stops, because the climate has no off-season. 6 min read Uses the Time Predictor How to Enter Irish Races: Ballots, Platforms and Club Membership Irish races are entered through a handful of local platforms — Eventmaster, MyRunResults, Pop Up Races and Eventrac — rather than the ones British runners know. The two biggest marathons, Dublin and Cork City, are both ballots. Everything else is first come, first served, priced in euro, and generally cheaper than the British equivalent. 5 min read Racing in Ireland from the UK: Travel, Money and What Changes British runners need no visa for Ireland under the Common Travel Area, and can use a driving licence and travel without a passport in principle, though carriers require photo ID. The currency is the euro, not sterling. Flights run from most UK airports and ferries from Holyhead, Liverpool, Pembroke and Fishguard carry cars and bikes cheaply. 6 min read Uses the Time Predictor Running in Dublin: Phoenix Park, the Coast and the Mountains Dublin gives you three distinct running environments within half an hour of the centre: Phoenix Park, at 1,750 acres one of the largest enclosed city parks in Europe; a coastal path running from Sandymount out to Howth Head; and the Dublin and Wicklow mountains rising directly behind the southern suburbs. There are 26 parkruns in the county. 5 min read Uses the Pace Calculator Running the Wicklow Mountains: The Way, the Races and the Ground The Wicklow Way is Ireland's oldest waymarked trail, running 127km from Marlay Park on the southern edge of Dublin to Clonegal in County Carlow. It is the backbone of Irish trail and ultra running, carrying the 127km Wicklow Way Race in July, the 50.5km Maurice Mullins in March, and part of the Art O'Neill Challenge in January. 5 min read Running the Wild Atlantic Way: Connemara, Kerry, Clare and Donegal Ireland's Atlantic coast carries the races people travel for: the Connemarathon through the Inagh valley, the Clare Burren Marathon across limestone pavement, the Dingle Marathon on the Slea Head road and the Kerry Way Ultra's 200km circuit. All of them are wind races before they are anything else. 6 min read Triathlon in Ireland: The Scene, the Races and the Water Irish triathlon is small, mountainous and cold. Hardman Killarney is billed as the country's only full distance; the Lost Sheep at Kenmare crosses three mountain passes in 83km; the Hell of the West at Kilkee has run since 1985 and is named for the wind. Water temperatures mean a wetsuit essentially year-round. 5 min read Uses the Split Calculator Running in Ireland County by County: All 26, and What Each One Has All 26 counties in the Republic have at least one parkrun, from 26 in Dublin down to one each in Carlow, Kilkenny, Laois, Longford and Louth. Dublin, Galway, Kerry and Cork carry the bulk of the race calendar; the midlands and border counties run smaller club fixtures that rarely appear in national listings. 9 min read

Running and racing in Australia

A calendar that peaks in winter, a heat problem measured in dew point rather than degrees, the largest parkrun scene outside Britain, and the country that produced most of modern triathlon.

Running in Australia: What the Heat Actually Does, City by City Australian heat is a dew point problem, not a temperature problem. At 6am in January, Perth averages 19.7°C and Brisbane 21.6°C — nearly the same reading — but their dew points are 12.6° and 19.9°, which puts Perth in a 1-2% pace penalty and Brisbane in 2-3%. Darwin at the same hour sits at 26.9°C and a 24.4° dew point: a 4.5-6% penalty before sunrise. 7 min read Uses the Heat Pace The Australian Racing Calendar: How the Year Is Actually Shaped The Australian racing year peaks in the southern winter. The big road marathons cluster between April and October — Canberra in April, Gold Coast in July, Sydney in August, Melbourne in October — because that is when the weather allows fast running. Summer, December to February, is the off-season for road racing and the season for trail and mountain events in the south. 5 min read Uses the Time Predictor How to Enter Australian Races: Ballots, Sell-Outs and Entry Platforms Australia has no single national entry system. Sydney runs a heavily oversubscribed free ballot with charity and travel-package alternatives; Gold Coast opens entries the preceding December and sells out on a first-come basis; Melbourne uses a ballot plus a time-qualifying route. Smaller races enter directly through the organiser, often right up to race morning. 5 min read Uses the Time Predictor Racing in Australia from Overseas: Seasons, Flights and What Changes The season is the first thing to get right: Australia races in its winter, which is the northern summer, so a European or American runner travels in June to August for the best conditions. Allow at least five days on the ground before racing — one per hour of time difference is the common rule, and Sydney is nine or ten hours from London. 5 min read Uses the Time Predictor Running Safety in Australia: Heat, Sun, Snakes and Magpies The genuine risks of running in Australia are, in order: heat and dehydration, ultraviolet exposure, and running out of water in remote terrain. Snakes and spiders make the headlines and cause almost no incidents involving runners. Magpie swooping season, roughly August to October, is the one distinctively Australian nuisance and is best handled by changing your route. 6 min read Uses the Heat Pace parkrun in Australia: 549 Events, and Why the Start Time Moves Australia has 549 parkrun events: 544 weekly 5K parkruns and 5 junior parkruns. Start times run from 7:00am to 9:00am and follow the state only roughly — Queensland and the Northern Territory are 7:00am throughout, Tasmania 9:00am, most of the rest 8:00am, but 19 New South Wales events and 7 Western Australian ones start at 7:00. Queensland has the most, with 139. 5 min read Uses the Pace Calculator Running in Sydney: The Harbour, the Coast and the Bays Sydney's running is built around water. The Bondi to Coogee coastal path is about 6km one way on cliff-top boardwalk and stairs; the Bay Run at Iron Cove is a flat 7km loop; Centennial Park's Grand Drive is a 3.8km circuit and the city's default speed session. All three are busiest between 6am and 8am, which is also when the city is coolest. 5 min read Uses the Heat Pace Running in Melbourne: The Tan, Beach Road and the Yarra Melbourne is the flattest and most temperate of the big Australian cities, and the easiest to run in. The Tan Track around the Royal Botanic Gardens is 3.827km and the city's default loop; the Capital City Trail runs about 29km around the inner suburbs; Beach Road runs flat along Port Phillip Bay for tens of kilometres. It never records a morning above 24°C. 5 min read Uses the Pace Calculator Running in Brisbane: The River Loop, Mt Coot-tha and a Subtropical Year Brisbane's running centres on the river: the Bicentennial Bikeway and the New Farm Riverwalk form a continuous traffic-free path through the city, and the standard loop crossing at Goodwill and Story Bridges runs roughly 5-10km depending on the bridges you choose. The city's real advantage is winter — a July dawn averages 10.6°C at an 8.1° dew point, which is the best racing weather in Australia. 4 min read Uses the Heat Pace Running in Perth: The Swan River, Kings Park and a Dry Heat Perth's running is organised around the Swan River, where a series of bridge-to-bridge loops give 5km to 20km on continuous traffic-free path. Kings Park sits above the city with bushland trails and the Jacob's Ladder stair climb. Perth is hotter than Sydney by day but far drier — its January dawn dew point is 12.6° against Sydney's 18°. 5 min read Uses the Heat Pace Trail Running in Australia: The Ranges, the Coast and the Long Ones Australian trail running is concentrated in a handful of ranges rather than spread evenly: the Blue Mountains west of Sydney, the Victorian high country and Dandenongs, the Queensland hinterland, the Perth Hills and the Bibbulmun Track, and Tasmania. Ultra-Trail Australia at Katoomba is the largest event, a UTMB World Series Major with distances from 11km to 161km. 6 min read Uses the Pace Calculator Triathlon in Australia: Where the Sport Grew Up Australia has one of the deepest triathlon cultures in the world. The Noosa Triathlon in November is among the largest Olympic-distance races anywhere; Ironman holds full-distance races at Cairns in June, Port Macquarie in May and Busselton in December, with 70.3 events across most states. The season runs through the southern summer, October to March, because the swim decides it. 5 min read Uses the Split Calculator Open Water Swimming in Australia: Ocean, Surf and the Big Crossings Australian open water swimming is overwhelmingly ocean swimming, with a large summer series calendar of 1km to 5km beach races. The two signature events are the Rottnest Channel Swim, a 19.7km crossing from Cottesloe in February, and the Sydney and Queensland ocean swim series. Ocean pools — tidal rock pools along the coast — are the standard training venue. 4 min read Uses the Swim Pace

Running and racing in Jamaica

What permanent heat actually costs you, how to train and race in it, where the water and the trails are, and how a road race here really works.

Running in Jamaica's Heat: What It Actually Costs You Expect to run roughly 2-4.5% slower in Jamaica at dawn than in cool British conditions, and more later in the day. At 06:00 in September Kingston averages 24.8°C air with a 23.2°C dew point — an index of 150 — against 12.3°C and 10.8°C for London. Waiting until 08:00 pushes you into a harder conditions band in ten months of the twelve. 8 min read Uses the Heat Pace The Best Time of Year to Run in Jamaica January to March is the best time of year to run in Jamaica. Kingston's dawn conditions index sits at 139 in those months against 150 from June to September, rain days are at their lowest, and only 1-3% of mornings start at or above 24°C compared with 78-82% in high summer. December is the other strong window, and it is when the Reggae Marathon is held. 8 min read Uses the Heat Pace Training in Jamaica: How to Build a Block With No Off-Season In Jamaica you periodise by time of day and altitude rather than by season, because there isn't one. Kingston's 06:00 conditions index runs from 139 in January to 150 from June to September — a narrow band that never gets easy. Put quality sessions at first light, run everything to effort rather than pace, and use the 600m plateau around Mandeville when you need genuinely cooler air. 10 min read Uses the Heat Pace Running Safety in Jamaica: Heat, Traffic, Rain and Route Choice The genuine risk hierarchy for a runner in Jamaica is heat first, traffic second, and everything else a long way behind. Run at first light, run known routes at the hours other people are out, prefer company to solitude, face oncoming traffic on the right-hand side of the road since Jamaica drives on the left, and never cross a flooded gully. 9 min read Uses the Heat Pace Running a Road Race in Jamaica: What Race Day Is Actually Like Jamaican road races start early — pre-dawn is standard and the Team Sangster 10K in Montego Bay goes off at 06:00 — and the calendar is dominated by 5Ks and 10Ks with a strong charity and corporate presence. Entry is usually straightforward and often possible close to the day. The Reggae Marathon weekend in December is the biggest event, now staged in Kingston rather than Negril. 7 min read Uses the Heat Pace What to Wear Running in Jamaica: Kit for Permanent Heat Wear as little as you reasonably can, in light colours and genuinely technical fabric, and own more sets than you think — nothing dries overnight in this humidity. Carry fluid on anything over about 40 minutes, use electrolytes rather than plain water on long runs, and treat sun cover and a hydration vest or handheld as core kit rather than accessories. 7 min read Uses the Heat Pace Running in Jamaica as a Visitor: A Practical Guide Run at dawn, run with people rather than alone, and plan around the humidity rather than the temperature. Jamaica's road-racing calendar runs year round and most events start before sunrise. The practical constraints for a visitor are heat management, route knowledge and finding company — not fitness. 5 min read Uses the Heat Pace Running Clubs in Jamaica: How to Find People to Run With Jamaica's running club scene is concentrated in Kingston. Jamdammers Running Club, which grew out of a loose group meeting at Mona Reservoir and formalised in June 1995, is the best known — it created the Reggae Marathon in 2001 — and Pacers Running Club is one of the largest. Groups meet early morning, and turning up at an established venue at the established hour is the practical way in. 8 min read Uses the Pace Calculator Open Water Swimming in Jamaica: What the Sea Is Actually Doing Jamaican sea temperatures sit at roughly 27-30°C all year, coolest around January and warmest in late summer. That is above every federation's wetsuit ceiling — 24.6°C under World Triathlon and British Triathlon, 28.8°C under IRONMAN — so open water swimming in Jamaica is a skins proposition in every month of the year. The problems to plan for are sun, overheating and boat traffic, not cold. 10 min read Uses the Wetsuit Calculator Triathlon in Jamaica: The Races, the Scene and What to Expect Jamaican triathlon is small and centred on two events: Jake's Off-Road Triathlon at Treasure Beach — a 300m ocean swim, 25km mountain-bike leg and 7km trail run, and the world's longest-running off-road triathlon — and the Jamaica Triathlon Association's sprint triathlon and aquathlon at Port Royal, which doubles as CARIFTA selection. Dates are published through social media rather than a race website. 8 min read Uses the Split Calculator Trail Running in Jamaica: The Blue Mountains and Cockpit Country Jamaica's trail running is concentrated in the Blue Mountains behind Kingston and the karst interior of Cockpit Country. Blue Mountain Peak is 2,256m — about 10km and 1,000m of climb from the Whitfield Hall trailhead, and an expert proposition on foot at speed. Catherine's Peak is the realistic first outing. Almost none of it is waymarked for runners, so a guide or local company is the norm rather than a precaution. 7 min read Uses the Pace Calculator Where to Run in Kingston: The Routes Locals Actually Use The four places Kingston runners go are Emancipation Park (a floodlit 500m rubberised loop, open from 05:00), Mona Reservoir (a 2.6km dirt circuit that requires an annual joggers' pass from the National Water Commission), the UWI Mona campus, and Palisadoes Road out towards Port Royal.

Questions these guides answer

How much slower will I run in Jamaica?

At dawn, roughly 2-4.5% slower than in cool conditions, based on Kingston's 06:00 index running from 139 in January to 150 from June to September. On a 3:40 marathon that is about four to ten minutes depending on the month. Later starts cost more, and if you are not acclimatised expect the upper end of whichever band you are in.

What time of day should I run in Jamaica?

At dawn. In Kingston the index climbs about six points between 06:00 and 08:00, and in ten months of the year that is enough to push you into a harder conditions band. No adaptation available on a short trip comes close to that. Evening runs are the second-best option, but the dew point stays high after dark so they are less of a relief than they feel.

Is it humid in Jamaica all year, or just in summer?

All year. Kingston's dew point at 06:00 ranges only from about 19.9°C in the driest month to 23.2°C in September across the eleven-year archive. Unlike the UK, where conditions swing enormously between seasons, there is no month in Jamaica where humidity stops being the main variable in your running.

How long does it take to acclimatise to running in the heat?

Ten to fourteen days of training in the heat produces most of the measurable adaptation — expanded plasma volume, earlier and more dilute sweating, and a lower heart rate at the same effort. You will feel a difference within about a week, and your first three or four runs after arriving will feel disproportionately hard.

Why does dew point matter more than humidity for runners?

Relative humidity is relative to temperature, so 80% means something very different at 5°C than at 30°C. Dew point is absolute — it tells you how much moisture the air actually holds, which is what determines whether your sweat can evaporate and cool you. Two mornings with the same relative humidity can be completely different runs.

Where can I run in Kingston as a visitor?

Emancipation Park is the easiest answer — a 500m rubberised loop in New Kingston, open from 05:00, floodlit, and walkable from most hotels. For longer runs, the UWI Mona campus and the residential Barbican routes are what locals use, and Palisadoes Road towards Port Royal gives you flat, uninterrupted distance.

Do you need a pass to run at Mona Reservoir?

Yes. The reservoir is managed by the National Water Commission and jogging there requires an annual joggers' pass, processed in person and valid for a year. It is the best loop in the city — a 2.6km dirt circuit with Blue Mountain views — but it is not somewhere you can simply turn up and run, so sort it before you travel.

How long is the loop at Emancipation Park?

The jogging track through Emancipation Park is 500 metres of rubberised surface, about eight feet wide. That makes it twenty laps to a 10K, which is why most people use it for easy running and intervals rather than long runs. The park opens at 05:00, before sunrise year round.
