Progress against the field
Justin Rivest has gained 10:37 on the field from Ottawa 2026 to Boston 2026.
The clock says 18:50 faster, but the races themselves got 8:13 quicker for everyone.
The biggest step was Ottawa 2026 → New York 2026: 16:15 on the field in 14 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.
