Ironman Langkawi 70.3 is a 70.3 (half-distance) triathlon in Malaysia, part of the Ironman calendar. The next edition is on 21 November 2026. The course is 1.9 km of swimming, 90 km on the bike and 21.098 km of running.
Climbing adds up to 736 m, 715 m on the bike and 21 m on the run, a moderate amount for the distance. The course is described as hilly.
Water temperature is typically around 28 °C, above the 24.5 °C limit, so wetsuits are not permitted for age-group athletes.
Pacer Quest rates Ironman Langkawi 70.3 as Hard: 736 m of climbing (moderate); water 28 °C (no wetsuit); finishers +12% slower than the average 70.3. 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, 70 qualifying slots were shared among 464 ranked finishers, with slots allocated by age-graded rank under IRONMAN's performance-based system. For example, a M40-44 athlete needed roughly 5:35:59 and a F40-44 athlete needed roughly 5:30:09 to be inside the line.
