  In terms of actual personal bests, Kerr’s fastest mile is the 3:45.34 he ran to win at Prefontaine in 2024. But his 1500 personal best of 3:27.79, which he ran in the Olympic final two months later, is the superior performance.

His PR for 1500m is 3:27.79 and he ran 3:27.7 for 1500m today and then ran another 109+ metres.
