Progress against the field
Marc Tom has dropped 45:43 behind the field from Las Vegas 2026 to New York 2026.
The races barely moved for everyone else, so 46:07 slower on the clock is close to the whole story.
The biggest step was Las Vegas 2026 → Houston 2026: 6:49 on the field in 34 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.
