Progress against the field
From Amsterdam 2023 to Gent 2025, the field gained 9:30 on Jacco Borgman.
Over the same races everyone got 11:16 quicker, so 1:46 faster on the clock looks better than it was.
The longest gap between two races compared here, 615 days between Rotterdam 2024 and Gent 2025, cost 5:17 on 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.
