What racers and reviewers say
- Racecheck reviews, Sundowner Triathlon (176 written reviews)Raced 2026 · aggregator · Positive
Racecheck shows 4.31/5 all-time (4.61 in 2026) across 181 verified reviews, 176 with written text, covering Sprint, Olympic and 70.3 at Allerthorpe Lakeland Park. Reviewers agree the bike is flat and fast (99% say so) and the venue, staff and atmosphere are friendly, with 60% calling it ideal for beginners. Complaints centre on the run: rutted grass and gravel, a narrow towpath section and twisty laps. The 2025 relaunch had queues at registration and transition, unclear signage, timing errors and a crowded, low-water swim; 2026 scores rose but aid stations ran out of water.
“Amazing course and support, everything was top-notch.”
- Racecheck review, Sharon B. (2026 sprint)Raced 2026 · aggregator · Positive
Liked the women-only swim waves and standing start in shallow water, which made the sprint less daunting. Bike was flat and smooth with no potholes. Disliked gel wrappers dropped on the course and found the run long and twisty, and muddy if it has rained.
- Racecheck review, Louise O. (2025 sprint)Raced 2025 · aggregator · Mixed
Disappointed that the sprint swim was cut to about 500 m (1,640 ft) because of water levels, leaving around 12-13 minutes in the water after buying a wetsuit and kit. Felt the shortening was announced too late and the event should have been delivered to standard.
- Racecheck reviews, Philip N. and Tom P. (2025 sprint)Raced 2025 · aggregator · Negative
Two critical 2025 sprint entrants. One cited poorly marked transition entry and exit, public walking across run routes and the finish area, too few marshals, a swim distance changed minutes before the start, and a weak start signal. The other got no pre-race information and found racking security heavy-handed and chaotic.
- Racecheck review, Caroline W. (2025 sprint)Raced 2025 · aggregator · Mixed
Good race with a changed route, but the sprint split on the bike course had no marshal and several entrants missed the turn. Another 2025 sprinter says blue arrows were hard to see and ended up on the Olympic bike route.
