Progress against the field
Olivier Iserbyt has dropped 11:54 behind the field from Maastricht European Championships 2023 to Belgium 2025.
The clock says 4:40 slower, but the races themselves got 7:14 quicker for everyone.
686 days between Rotterdam 2023 and Belgium 2025 is the longest gap compared here, and the second race was 15:30 behind 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.
