Triathlon & Open Water Endurance

Cycle 100 Miles (Century Ride)

Elective. A century ride — the cycling benchmark that proves you have the aerobic base and saddle endurance for long triathlon bike legs.

Complete First Open Water Swim (1km)

Elective. 1km in open water. Pool swimming and open water swimming are fundamentally different — sighting, temperature, and current demand specific preparation.

Complete Your First Sprint Triathlon

Required. Sprint distance: ~750m swim, 20km bike, 5km run. The anchor event where T1 and T2 transitions, multi-sport pacing, and race-day logistics become real, not theoretical.

Complete a 70.3 Half-Ironman

Elective. 70.3 Half-Ironman: 1.9km swim, 90km bike, 21.1km run. The step-up that requires dedicated multi-sport training blocks and a full nutrition strategy.

Complete a Full Ironman

Elective. Full Ironman: 3.8km swim, 180km bike, 42.2km run. A multi-year project for most athletes — pacing and fueling are as important as fitness.

Complete 5km Open Water Swim

Elective. 5km open water swim — a dedicated open water racing event where swimming is the entire sport.

Complete an English Channel Relay

Elective. English Channel relay crossing (6-person team, each member swims one leg). The most prestigious open water relay in the world. Requires Channel Swimming Association sanction.
