Triathlon Fundamentals and Race Formats
Domain 1: Triathlon Fundamentals and Race Formats tests how well you map distances, rules, and race formats onto athlete preparation. You need to recognize standard distances, drafting status, relay rules, and the constraints each format places on pacing and equipment.
Core distances and formats
- Sprint: 750 m swim, 20 km bike, 5 km run. Standard/Olympic: 1.5 km, 40 km, 10 km. Middle/half: 1.9 km, 90 km, 21.1 km. Long/full: 3.8 km, 180 km, 42.2 km.
- Draft-legal racing is typically elite/ITU-style; age-group races are usually non-drafting unless the race briefing says otherwise. Drafting changes bike tactics, pack skills, and penalty risk.
- Other formats include duathlon (run-bike-run), aquathlon (swim-run), aquabike, and mixed relay with short supersprint legs.
- Wetsuit rules depend on water temperature and distance. World Triathlon rules make wetsuits compulsory below 16°C and generally forbidden above 24.5°C, with distance-specific allowances between those thresholds.
- Cut-off times, penalty tents, and transition flow can decide results as surely as fitness.
Worked example
An athlete asks whether a 1.9 km/90 km/21.1 km race is a “half Ironman.” Yes-it is middle-distance or 70.3, not standard distance. If the race is draft-legal, her bike training must include pack riding and surging; if it is age-group non-drafting, steady power and legal spacing matter more. The distance label alone does not tell you drafting status.
Traps that cost marks
Confusing Olympic with half distance; assuming every triathlon is non-drafting; missing relay format rules; treating wetsuit legality as universal; ignoring race-specific cut-offs.
Key points
- Sprint = 750/20/5; Olympic = 1.5/40/10.
- Half = 1.9/90/21.1; full = 3.8/180/42.2.
- Drafting status changes tactics and training.
- Relay and aquathlon rules differ from standard triathlon.
- Wetsuit legality is temperature- and distance-dependent.
