Progress against the field
Between Rotterdam 2024 and Hamburg 2026, Boy Wouda pulled 4:33 ahead of the field.
Over the same races everyone got 14:34 quicker, so 19:07 faster on the clock looks better than it was.
The longest gap between two races compared here, 404 days between Belgium 2025 and Heerenveen 2026, still ended 17:43 ahead of the field.
How this is worked out ⓘ
A finish time moves for two reasons: the athlete, and the race — its course, its floor, its day. For each pair of races in a row in one category, we take everyone who raced both and use the middle of how much they moved (the median) as "the race". Whatever is left is the athlete. Doubles are compared only when the same two people raced both, and told as the pair's; relays are left out. A pair with fewer than 15 athletes in common is not shown. The summary above covers Individual Open · Men, the one raced most; every comparison is in the list below.
