Race Conditions
Ironman Japan is always one of the slowest races, and this year was no exception with an adjustment of -27:28 mainly because of a very slow bike.
Male Race Results
The race was decided on the bike: Swen Sandberg posted the fastest bike ride of the day and won by a comfortable margin. Patrick Evoe used his strong bike and fastest run to finish second, followed by early race leader Simon Cochrane.
