2027 calendar
This directory currently links 36 race guides, including 23 with a listed 2027 date. Compare verified dates across sports in the 2027 race calendar. Dates marked to be confirmed remain unverified; they are not announcements.
Choose the event before the plan
Compare date, travel, course or venue demands, entry status and the time you can train consistently. Then use the IRONMAN training hub to choose a realistic runway. A longer plan is useful when it creates gradual foundation work and recovery margin—not when it adds more hard sessions.
The Long-course triathlon research separates practical signals from study limits before you turn a benchmark or protocol into training.
What must still be checked
Global directories do not contain every race-week fact. Before entering or travelling, open the official event page and confirm eligibility, start schedule, venue, course maps, equipment, cutoffs, athlete briefing, transport and cancellation terms. Recheck close to race day because organiser details can change.
Training and safety boundary
The guides are educational planning resources. They do not diagnose injury, certify open-water or cycling safety, prescribe an individual medical or nutrition plan, or guarantee a finish. Use appropriate supervision and qualified support for material safety or health concerns.
