Progress against the field
Sander Van Rooijen has gained 1:37 on the field from Amsterdam 2026 to Stockholm 2026.
The races themselves barely changed, so 1:15 faster on the clock is the real picture.
The biggest step was Amsterdam 2026 → Mechelen 2026: 5:27 on the field in 64 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. The summary above covers Individual Pro · Men, the one raced most; every comparison is in the list below.
