Measured on the clock
15–95 · mean 44
Half marathons, marathons and 10Ks measured against official data: the World Athletics label, the strength of the field (Competition Performance Ranking), a SuperHalfs series bonus, and a trust bonus for AIMS membership / European Athletics 5-star / a Jones Counter-measured course. When a race clears 90 it's because the numbers actually put it there.
