Progress against the field
Jacqueline Samanta Ornelas Arredondo has dropped 8:52 behind the field from Ciudad de Mexico 2024 to Mexico City 2026.
Over the same races everyone got 10:24 quicker, so 1:32 faster on the clock looks better than it was.
The longest gap between two races compared here, 272 days between Guadalajara 2025 and Mexico City 2025, cost 31:07 on the field.
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.
