Progress against the field
Between Amsterdam 2024 and Heerenveen 2026, Iwan Bockkom pulled 10:28 ahead of the field.
The clock says 22:48 faster, but the races themselves got 12:20 quicker for everyone.
204 days between Rotterdam 2025 and Maastricht 2025 is the longest gap compared here, and the second race was 9:32 better than 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.
