Progress against the field
Dawn Marie Peterson has dropped 4:15 behind the field from Boston 2025 to Anaheim 2025.
The races barely moved for everyone else, so 4:11 slower on the clock is close to the whole story.
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 Open · Women, the one raced most; every comparison is in the list below.
