ProHyroxStatsWhich races saw the biggest performance jumps. Each finisher is scored against their own recent form, not the rest of the field, so field strength does not decide the ranking. Three numbers per race:
- Speed: the median improvement across qualifying finishers. For each one, their time in this race is compared to their best singles time in the prior 365 days. Higher means more of the field beat their recent best.
- PB Rate: the share of qualifying finishers who beat their best time from the prior 365 days.
- N: the number of qualifying finishers, meaning athletes with at least one prior singles race in the last 365 days. Men and women are pooled.

How it's measured & caveats
- Per finisher, the improvement is (recent best minus this time) / recent best. Speed is the median of those values across the field.
- Events with fewer than 10 qualifying finishers are hidden by default. Small samples are noisy.
- A single prior race is easy to beat, so scores skew slightly positive, and athletes early in their progression set PBs often.
- Weather, altitude and championship tapering also affect how fast a race runs.
