Knokke-Heist, Flanders, Belgium
A pure power course on the Belgian coast: flat polder roads, flat run, and wind as the decisive factor.
1.9 km swim in the sheltered Leopold canal / Zwin inlet water beside the coast, flat and current-free.
Pancake-flat one-lap 90 km bike through the Flemish polders — exposed, straight roads where North Sea wind is the only real obstacle.
Flat two-lap 21.1 km run along the seafront dike and promenade of the Belgian coast.
Actual monthly averages from the last 3 years (Open-Meteo). Real race day may vary.
Water temp uses athlete-reported values first, then official race data, then the marine archive (sea swims, measured at the nearest offshore point). Values tagged est. are modelled from recent air temperature for lakes and rivers, where no observational data exists.
