Progress against the field
Between Rotterdam 2025 and Stockholm 2026, Klaske Bouwmeester and Jeen Bouwmeester lost 13:29 to the field.
Over the same races everyone got 9:16 quicker, so 4:13 slower on the clock looks better than it was.
203 days between Heerenveen 2025 and Utrecht 2025 is the longest gap compared here, and the second race was 13:48 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.
