Birmingham Triathlon (Sutton Park)
Sutton Coldfield, United Kingdom · July · UK Triathlon (Rotary Club parking charity)
Why people love it
- Open-water swim in Powell's Pool, a 48-acre (19.4 ha) park lake, with safety kayaks and white caps for novices.
- Bike and run are lapped near the arena, so supporters see you many times.
- Run mixes grass, tarmac and heath; reviewers rate it the best part of the day.
- Parking on the grass next to registration for 3 pounds, with one transition.
- Pack pickup is open Friday 14:00 to 17:00 as well as race morning from 05:45.
Watch out for
- All athlete reviews date from 2015 to 2017. The 2026 race pack still mentions the same unrepaired road surface.
- Park bike roads are potholed and marked with spray paint; crashes were reported in 2017, so use a road bike.
- The Olympic bike is eight 5 km (3.1 mi) laps that you count yourself; one 2017 entrant measured it short.
- Cattle, dogs and walkers can be on the bike course even though it is closed to traffic.
- Wetsuit is compulsory for the Olympic, and a 2016 reviewer found the sprint swim start aggressive.

What racers and reviewers say
- Racecheck (20 verified reviews)Raced 2017 · aggregator · Mixed
Racecheck shows 4.21/5 from 20 reviews (2017 average 4.10; all reviews 2015 to 2017). Reviewers love the setting, the relaxed organisers and the multi-lap layout that spectators can follow, and rate the run the best part. The shared complaint is the park bike course: potholes, several crashes in 2017, tight bends, cattle and walkers on the road, and eight boring laps for the Olympic. Event safety scores 3.60/5, the lowest rating. One entrant said the Olympic bike and run came up short of 40 km (24.9 mi) and 10 km (6.2 mi).
“It does feel special, given the lovely mixed terrain.”
