Progress against the field
Adam O’Sullivan has gained 7:09 on the field from Birmingham 2024 to Glasgow 2025.
Over the same races everyone got 7:06 quicker, so 14:15 faster on the clock looks better than it was.
The biggest step was Birmingham 2024 → Manchester 2025: 3:56 on the field in 91 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.
