Progress against the field
Between Cardiff 2025 and London Excel 2025, Natalie Ridler pulled 6:23 ahead of the field.
Over the same races everyone got 4:50 quicker, so 11:13 faster on the clock looks better than it was.
The largest gain on the field came from Cardiff 2025 → Birmingham 2025: 6:25 in 145 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.
