Official event pageWhat this race demands
The 5150 Knokke-Heist requires sustained aerobic output across a standard Olympic-distance triathlon format, combining a 1.5 km swim, a fast 40 km bike leg, and a 10 km run.
Aero position maintenance
The fast and flat 40 km bike leg rewards riders who can sustain a low, aerodynamic position for an extended period without significant drops in power output.
Bike-to-run transition
Executing a strong 10 km run immediately following a maximal effort on the bike requires high muscular endurance and pacing discipline during the opening kilometers.
