Progress against the field
Josje Wijckmans has dropped 2:24 behind the field from Amsterdam 2022 to Rotterdam 2024.
Over the same races everyone got 9:14 quicker, so 6:50 faster on the clock looks better than it was.
322 days between Rotterdam 2023 and Rotterdam 2024 is the longest gap compared here, and the second race was 3:49 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.
