What racers and reviewers say
- RaceCheck: AnonymousRaced 2024 · aggregator · Positive
Feels like a pro race: blue carpets, a digital finish gantry and a finish tape held for every finisher, with plenty of aid and a supportive crew.
- RaceCheck: Michael B.Raced 2024 · aggregator · Mixed
Fun pier-jump start, but some bike sections were too narrow and twisting for racing, and the final climbs after about 50 miles were extreme. Aid on the run every 2 km (1.2 mi) was good; no food at the finish.
- RaceCheck: AnonymousRaced 2024 · aggregator · Positive
Friendly, excellent organisation and good value. Traffic occasionally held up the front of the race and a couple of narrow roads were not closed.
- RaceCheck: Chris H.Raced 2023 · aggregator · Positive
First 70.3. Brilliant, picturesque, with a unique, not-too-high pier jump. The bike is mostly flat on good surfaces with potential for fast times.
- RaceCheck: Alex C.Raced 2023 · aggregator · Positive
Previously sceptical of local events after doing official IRONMAN races. Great communication, easy registration and transition, a challenging but scenic end to the bike and awesome marshals and spectators.

Multiple IRONMAN finisher calls it a fabulous day out and great value: a great pier swim, safe and mostly flat bike with a few easy hills at the end, flat run with excellent hydration.
- RaceCheck: Benedetta M.Raced 2023 · aggregator · Positive
Pier jump is amazing; the ride over Beachy Head is spectacular if it is not windy; the seafront run is great. Wants a closed road course after a car pulled out in front of her in the first kilometre.
- RaceCheck: Ben S.Raced 2023 · aggregator · Positive
Well organised and unique with its pier jump, easy-to-navigate swim, a bike that is two-thirds flat with two good hills near the end, then a flat two-lap run.
- RaceCheck: AnonymousRaced 2022 · aggregator · Mixed
Supportive staff but disappointed that nothing was offered at the finish on a hot summer day, and questioned the environmental ethics of low-quality T-shirts and medals.
- RaceCheck: AnonymousRaced 2021 · aggregator · Positive
Inaugural half: a jump off the pier at high tide, a circuit under the pier and along the beach with a little current, quick A roads on a very fast bike course and excellent value.
