Key Race Metrics & Overview
- Date
- Sunday, 15 August 2027
- Venue
- Roundhay Park, Mansion Lane, off Princes Avenue, Leeds LS8 2HH
- Distance
- Full Distance (140.6) — 226km total
- Start Time
- TBC — the 2027 date (15 August) comes from a single travel-booking aggregator, not yet confirmed via an official 2027 athlete guide. The 2026 edition ran 16 August 2026, from Roundhay Park.
- Draft-Legal Bike
- No — non-drafting
- Cut-Off
- Per the 2026 athlete guide: swim cut-off 2h20m; swim+T1+bike combined 10h30m (intermediate checkpoints at the start of lap 3/73mi by 14:30 and the personal-needs station at 90.7mi by 15:45); overall run/finish 17h from the swim start (intermediate: start of the last lap/20mi by 22:10). Finishing after 17h but before the course closes gets you an unofficial 'NC' (Not Classified) time rather than a DNF, but no age-group award or Kona slot.

Wetsuit outlook
Will you need a wetsuit at Ironman Leeds?
Water temperature at inland lake in August has typically been 16.6°C, ranging from 14.6°C to 17.9°C in eight of every ten years. Against IRONMAN / 70.3's thresholds for this race's 3800m swim, that means:
Wetsuit optional — and recommended
Up to and including 24.5°C (76.1°F) every athlete may wear a wetsuit and remain eligible for awards.

- Optional (recommended)9 of 16
What the organiser says
Per the 2026 athlete guide: permitted up to and including 24.5°C, prohibited above it, and compulsory below 16°C. Maximum wetsuit thickness 5mm; De Soto Water Rover and Speedo Elite Triathlon wetsuits (forearm reinforcement) are banned.
Estimated from air-temperature history — no direct measurement of this water exists, and small, shallow venues tend to run a degree or two warmer than shown. The official temperature is taken an hour before the start, and only that reading decides the rule on the day.
Transitions
A single transition area is set up at Roundhay Park for both T1 and T2, with a short climb noted on the way out of T2.

Where Ironman Leeds starts and finishes
Ironman Leeds starts at Roundhay Park, Mansion Lane, off Princes Avenue, Leeds LS8 2HH and finishes at Waterloo Lake, Roundhay Park. 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 .

On the day
- Maurten is Ironman's official on-course nutrition brand globally — bike aid stations (2026: miles 13.2/34.1/47.8/68.6/82.2/103.1) had water, Precision Hydration 1000, bananas and Maurten bars/gels (black wrapper = non-caffeinated GEL 100, white = caffeinated GEL 100 CAF 100); run aid stations (roughly every 1.5 miles) added cola and sweet/salted snacks to the same line-up.

- Timing chip worn on the left ankle for the whole race — it is on loan and you are charged for a replacement if it is not returned at the finish.
