What racers and reviewers say
- RaceCheck (Amy K.)Raced 2015 · aggregator · Positive
First-year edition under the IRONMAN banner. Reviewer liked the town, weather and organisation, and would return. Bike starts technical with cobbles and sharp turns, then flat, straight and fast with good tarmac and strong crowds back into town. Run has a gradual long incline and seafront headwind; expo and early racking were inconvenient.
