Also this weekend
A single course, entered in four ways: as an individual triathlon, as an aquabike (swim and bike only, no mountain run), as a relay team of two or three, or in the sportive wave, where the three disciplines are grouped rather than raced continuously.
Leg 1 of 3
Swim — 1.5km
A 1.5km (roughly one mile) open-water swim in Ullswater, starting from Jenkins Field at the southern end of the lake. Clear, deep, and cold — this is a mountain lake in early September, not a managed venue.
- Venue
- Ullswater, from Jenkins Field at Glenridding
- Elevation gain
- No official figure published — see notes above
- Surface
- Lake — open water, cold.
Wetsuit: No fixed temperature threshold is published — the swim happens in a protected SSSI under Natural England permission, and organisers require a pre-race wetsuit inspection (clean and dry) rather than stating a mandatory/optional/banned rule. Ullswater in September is cold enough that a wetsuit is standard practice regardless.
Leg 2 of 3
Bike — 59km
Roughly 38 miles around the northern and central fells: along the shore of Ullswater, then climbing through Matterdale End, Troutbeck and Threlkeld before running down through Grasmere and Ambleside. The sting is the return over Kirkstone Pass — approached via the Struggle out of Ambleside, one of the most infamous road climbs in Britain, before the descent back to Glenridding.
- Venue
- Ullswater, Matterdale, Threlkeld, Grasmere, Ambleside and Kirkstone Pass
- Elevation gain
- No official figure published — see notes above
- Surface
- Road — open to traffic, with serious sustained climbing.
Non-drafting
Leg 3 of 3
Run — 15km
A 15km (roughly 9 mile) mountain run from Glenridding to the summit of Helvellyn at 3,118ft and back down, with 950m of ascent. This is genuine fell terrain — rock, scree and mountain path — attempted after a lake swim and a ride over Kirkstone.
- Venue
- Helvellyn, from Glenridding to the 3,118ft summit and back
- Elevation gain
- 3117ft
- Surface
- Mountain — rugged fell path, rock and scree.
Transitions
Transition is at Jenkins Field in Glenridding, serving both T1 and T2 — the swim finishes there and the run starts and finishes there.

Where Helvellyn Triathlon starts and finishes
Helvellyn Triathlon starts at Jenkins Field, Glenridding, Cumbria CA11 0PB and finishes at Ullswater, from Jenkins Field at Glenridding. We haven't been able to place those on a map accurately enough to show one — a pin in the wrong place is worse than no pin.
These are the start and finish points, not the route. Verus doesn't hold course files for this race, and drawing a line between two pins would be a guess you might end up training on. The official course map is the one to use: view it on the organiser's site .

Race Day Info & Checklist
On the day
- An 08:00 start from Jenkins Field, Glenridding.
- The run leg goes to the actual summit of Helvellyn at 3,118ft, with 950m of ascent — mountain kit rules apply, not road-run rules.
- A cut-off at Red Tarn (below the final summit climb) turns back anyone who will not make it safely, with a sweeper behind the last competitor.
- Aquabike, relay and sportive-wave options exist for anyone who wants the swim and the Kirkstone climb without the mountain.
- Proceeds support the Brownlee Foundation.
- There are no feed or drink stations anywhere on the run — you carry everything yourself. Organisers advise finishing both bike bottles before T2 and stashing a spare for the mountain leg.
- MP3 players and headphones are banned for the entire race, not just the run. Your wetsuit must be washed before you leave transition — your bike is held until that's done.
- A working rear bike light is compulsory, since Kirkstone Pass is often in cloud.
- Timing chip worn on a neoprene ankle strap — recommended under the wetsuit so it doesn't come loose in the swim. There's a £10 fee for a lost or unreturned chip.
Checklist
- A wetsuit for Ullswater in September — cold, deep, mountain lake water
- Fell or trail shoes for the Helvellyn leg, packed in T2: road shoes are not adequate on scree
- Whatever mountain kit the organiser mandates for the run leg — check the current list, because weather on Helvellyn can be a different season to Glenridding
- Warm layers for T2, since you arrive there wet from the swim and cold from the Kirkstone descent
- Low gearing on the bike: the Struggle out of Ambleside is one of the hardest surfaced climbs in the country
- A realistic plan against the 14:30 Red Tarn cut-off, worked backwards from your expected swim and bike times
Transport, Spectating & Where to Stay
Transport
Penrith is the nearest station, on the West Coast Main Line, around 12 miles from Glenridding with a bus or taxi onward. There is no rail service into the Ullswater valley itself.
King George V Playing Fields is the designated race-day car park, Sunday only, £5/car (the fee supports a local playing-fields charity), around a 10-minute walk to registration/transition. Pier car park, Glenridding village and the Glenridding Hotel car park are all explicitly off-limits.
The bike leg runs on open roads, so no closures — ride accordingly, particularly on the Kirkstone descent.
Spectator guide
Jenkins Field at Glenridding covers the swim exit, both transitions and the finish, which makes it the single best place to stand. Kirkstone Pass summit is the classic spot for the bike, and the lower slopes of the Helvellyn path let you see runners on the way up and the way down.
The A592 over Kirkstone links Glenridding to Ambleside and is the only practical way to follow the bike course — it is also the road the race is on, so plan around it rather than driving it during the race.
Where to stay
Glenridding / Patterdale
+ At the venue, on the lake, walkable to transition and the start. The obvious base for an 08:00 start.
– Very limited accommodation, and it books out early for race weekend.
Pooley Bridge / Ullswater north end
+ More choice around the northern end of the lake, still on the bike course, and easier to reach from the M6.
– A drive along the lake to the venue on race morning, on a narrow road.
Penrith
+ The best transport links and the widest choice of rooms, with the M6 and the mainline station.
– Around 12 miles from Glenridding and entirely out of the mountains — you lose the point of the weekend.

Does the Helvellyn Triathlon really go to the summit?
Yes — the run leg climbs to the actual summit of Helvellyn at 3,118ft, with 950m of ascent, and comes back down the same mountain.

Can you do the Helvellyn Triathlon without the mountain run?
Yes. There is an aquabike category covering the swim and bike only, plus relay teams of two or three and a sportive wave where the disciplines are grouped rather than raced continuously.

When were Helvellyn Triathlon results published?
Results only exist once the race has been run. Check back here, or the official results page, after it takes place.
Are there aid stations on the Helvellyn Triathlon run?
None at all — you carry every drop of water and food yourself for the whole mountain leg. Organisers advise finishing both bike bottles before T2 and packing a spare bottle specifically for the run.
