Progress against the field
From Dallas 2025 to Washington DC 2026, Clayton Marshall has moved with the field: what changed on the clock changed for everyone.
The clock says 4:40 faster, but the races themselves got 4:51 quicker for everyone.
The biggest step was New York 2026 → Washington DC 2026: 2:38 on the field in 98 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.
