Ironman (3.8 / 180 / 42.2 km)
Official website: ironman.com/races/im-western-australia
Ironman Western Australia is a full-distance Ironman triathlon in Australia, part of the Ironman calendar. The next edition is on 6 December 2026. The course is 3.8 km of swimming, 180 km on the bike and 42.195 km of running.
Climbing adds up to 250 m, 225 m on the bike and 25 m on the run, which makes it one of the flatter courses at this distance. The course is described as flat.
Pacer Quest rates Ironman Western Australia as Easy: 250 m of climbing (low); finishers -6% faster than the average Ironman. The rating is automatic and compares total climbing for the distance, water temperature and, where results exist, how finishers compare with the average for that distance.
At the 2025 edition, 75 qualifying slots were shared among 1088 ranked finishers, with slots allocated by age-graded rank under IRONMAN's performance-based system. For example, a M40-44 athlete needed roughly 9:42:30 and a F40-44 athlete needed roughly 9:41:33 to be inside the line.
Open the Race Lab to simulate this course with your own swim, bike and run paces, or use the Qualify module to place your time against these results. Registration and official details are on the organiser's website.
