* A history of competitive triathlon performance (= 2 years)
* Participation in at least four competitive triathlon events within the past 2 years
* Be in regular training for triathlon events
* A personal best time for a standard ½ Ironman race (1.9 km swim, 90 km cycle, 21.1 km run) in the last year of either:

* = 6 h 00 min, for men aged 18-40 years
* or =6 h 05 min for men aged 40-50 years
* or =6 h 20 min for men aged 50-60 years
