You can drive across Britain in a day and cross five completely different running landscapes doing it. That variety-per-mile is the country's real advantage over larger places, and it means the answer to "what is running in Britain like" depends entirely on which part you mean.
What follows is region by region, with race and parkrun counts from this site's own data.
London and the South East
141 races and 217 weekly parkruns — comfortably the densest running region in Britain, and the one with the most balanced calendar. It is the only region where road and trail racing are represented roughly equally rather than one dominating.
The defining terrain is chalk. The North Downs and South Downs run east-west across the region as two long escarpments, both carrying national trails, and between them they produce the classic southern ultras: Centurion's South Downs Way 50 from Worthing to Eastbourne with 5,700ft of climb, the North Downs Way 50 from Farnham over Box Hill, and Winter's End along the western South Downs in March.
Chalk runs fast and drains well, which makes the South East the best winter trail running in the country. It is also completely exposed on the ridge — the South Downs Way has essentially no shelter along its length, so wind matters more than gradient.
The Chilterns add beech woodland and short steep climbs north-west of London, giving Wendover Woods its 10,000ft-across-50-miles and the Chiltern Wonderland 50 its 5,600ft. Kent has the deepest club calendar of any county here — Canterbury 10, Folkestone, Deal, Sittingbourne, Sevenoaks Seven — and the South East generally is where Britain's imperial-distance club racing survives best.
The South West
42 races, 29 of them ultras, and 89 parkruns. The most ultra-dominated region in England, for one reason: the South West Coast Path.
At 630 miles it is the longest national trail in the country, and running on it is unlike anything else in Britain. The path descends to sea level at every cove and climbs straight back out, producing a saw-tooth profile that makes coastal races far harder than their distance suggests. Endurancelife's North Cornwall ultra packs 6,558ft into 31.4 miles — over 200ft per mile, and the steepest thing per mile in southern England.
The Arc of Attrition is the region's signature: 100-plus miles of Cornish coast path in January, starting at one in the afternoon so the whole field hits the cliffs in darkness. Dartmoor and Exmoor add genuine moorland — the Dartmoor Discovery is Britain's longest single-lap road ultra at 32 miles, and Exmoor has England's highest sea cliffs.
What the South West does not have much of is fast road racing. If you want a personal best, this is the wrong region.
The East
20 races and 99 weekly parkruns — five parkruns for every race, and the clearest sign anywhere in England of a running culture built on Saturday mornings rather than on the race calendar.
This is the flattest part of the country and the driest. Norfolk, Suffolk, Cambridgeshire, Essex and Lincolnshire give fen, heath, forest and long shingle coast, and the racing reflects it: Endurancelife's Suffolk ultra is the flattest in their series at 1,129ft across 32.7 miles, and the Norfolk and Suffolk coastal ultras are about surface rather than gradient — shingle and soft sand run slowly however level they are.
For genuinely fast, flat racing and for high-volume base training in winter, the East is the best region in Britain and the most overlooked.
The Midlands
28 races and 107 parkruns, and a region defined by one thing at its northern edge: the Peak District.
The Peak splits in two and they are different sports. The White Peak is limestone dale and trail, fast and dry. The Dark Peak — Kinder, Bleaklow, Edale — is deep peat and gritstone, and it is some of the hardest going in England. INFERNO at Edale sends runners up Ringing Roger and a waterfall with 10 to 15 miles between checkpoints; the Montane Spine starts at Edale in January and heads north for 268 miles.
Away from the Peak, the Midlands is canal and post-industrial trail, and it does that better than anywhere: the Ultra in the Black Country runs 32 miles around Dudley at 97% traffic-free on disused railway and towpath, and the Silkin Way Ultra follows a dismantled railway through Telford and the Ironbridge Gorge. Flat, firm, consistent and genuinely fast.
The North West
45 races, 31 of them ultras, and 78 parkruns. Two thirds of the racing here is ultra distance, and almost all of that is mountain running — the highest concentration of it in England. This is Cumbria's doing.
The Lake District is the centre of English mountain running: the Montane Lakeland 100 circles the entire range from Coniston with around 6,300m of ascent, the Lakeland 50 runs its second half, Lakes in a Day crosses the park north to south via Helvellyn with 4,000m of climb, and the Old County Tops links Helvellyn, Scafell Pike and Coniston Old Man at 270ft of ascent per mile — the steepest race on this site.
It is also where the Helvellyn Triathlon finishes on a 3,118ft summit, and where the Tour de Helvellyn runs 38 miles of winter fell four days before Christmas.
South and east of the Lakes, Lancashire and the West Pennine Moors give the Three Towers Ultra just under 9,000ft across 55 miles, and the Forest of Bowland is among the emptiest ground in England. Merseyside and Greater Manchester contribute the flat counterweight: Manchester to Liverpool on the Trans Pennine Trail, the Leeds and Liverpool Canal 130, and the Manchester Marathon, which is one of the two fastest big marathons in Britain.
Yorkshire and the North East
42 races, 32 of them ultras, and 105 parkruns. Yorkshire alone probably has more established ultras than any comparable area in Britain.
Three distinct landscapes. The Dales give limestone, the Three Peaks and the Fellsman — 61 miles, 11,000ft, 25 checkpoints and no marked course. The North York Moors give heather and the Cleveland Way, which the entire Hardmoors series is built on: the 55 across the moorland half, the 60 down the coast, the 110 for the whole trail. And the South Pennines give gritstone and deep peat — the Stanza Stones 50 from Marsden to Ilkley at 6,600ft, the Haworth Hobble at 5,300ft across 31.7 miles, and a Punk Panther race most months of the year.
Further north, Northumberland is the emptiest county in England and the Cheviot Goat crosses it in December with 9,500ft of climb and a 24-hour limit. The Northumberland coast is flat by contrast — Endurancelife's race there is 36.1 miles with only 1,631ft.
Wales
24 races on this site, 21 of them ultras. Wales is mountains, and the running reflects it almost entirely.
Eryri (Snowdonia) in the north gives the Dragon's Back Race — six days and 380km down the mountain spine of Wales from Conwy Castle to Cardiff with 17,400m of climbing, one of the hardest mountain races anywhere — plus the Snowdonia Trail Marathon, the Slateman through the Dinorwig slate quarries, and the Brutal Extreme Triathlon, whose run climbs Snowdon.
Bannau Brycheiniog (the Brecon Beacons) in the south carries the Beacons Way Ultra at 6,143m across 100 miles — a climb total comparable to the Lakeland 100 — plus Epona 100, the Black Beacon and the Beacons Ultra, which does two 23-mile loops with a Pen y Fan out-and-back added to the first.
The coast is the third element: the Wales Coast Path is the only continuous path around an entire country's coastline, and the Gower, Pembrokeshire and Anglesey races use it. Ring o' Fire circumnavigates Anglesey over three days.
Scotland
31 races, 26 of them ultras — the biggest, remotest running ground in Britain and the least densely raced.
The West Highland Way is the spine of it: 95 miles from Milngavie to Fort William, raced whole by the West Highland Way Race with a 35-hour limit, and in its southern 53 miles by the Highland Fling. The Loch Lomond shoreline between Rowardennan and Inversnaid is the section everyone talks about — technical rock and roots that break any rhythm you have built.
Beyond it: Salomon Skyline Scotland at Nevis Range, the closest thing Britain has to alpine skyrunning, with genuine scrambling on the longer races. Glenmore 24 in the Cairngorms, timed over the summer solstice when it barely gets dark. The Shetland Toe to Tip, 100 miles up the length of Shetland over three days. And the Cateran, the Tweed Valley, the Kintyre Way and a scattering of island races that are as much expedition as event.
Northern Ireland
Six races on this site, and the smallest coverage of any UK nation. The Causeway Coast marathon and ultra run the Antrim coast past the Giant's Causeway and the Shepherd's Steps; Norn Iron 100 crosses the country from Ballintoy to Gortin over the Sperrins; and the Mourne Mountain Marathon is a two-day team navigation event in the Mournes.
Worth knowing that the running scene here is effectively continuous with the Republic's — runners cross the border in both directions every weekend, and a trip that takes in Belfast and Dublin means two currencies and a switch between miles and kilometres on the road signs.
