Progress against the field
Laissa Ysebaert has gained 0:36 on the field from Mechelen 2026 to Maastricht 2026.
Over the same races everyone got 1:34 quicker, so 2:10 faster on the clock looks better than it was.
The largest gain on the field came from Mechelen 2026 → Rotterdam 2026: 6:51 in 20 days.
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.
