Unfortunately you can't link directly to the 1 mile results. Scroll down to the table, select "1 Mile Men", then select "Reports", then "Race Analysis" and/or "Race Analysis Graphical". That leads to these two PDFs (not sure these links are stable):

  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.

Putting it in 100m times is great perspective. This is essentially a healthy amateur athlete running at nearly full tilt for 4 minutes straight.

There were two men running in front of him for a while (and both just stopped eventually and just dropped off) - was it to "pull" him in their slipstream?

Partially. They're called rabbits[1] (or pacers) whose official role is to run a specific pace, who help encourage a fast race overall rather than a slow buildup with a fast kick.

		Very smart. Would be awesome if they had these in track cycling.
