His race showed remarkable consistency for the first three-quarters of the distance: from mile 1 through mile 20, his per-mile splits stayed tightly banded between 8:33 and 9:57, with cumulative pace holding right around 9:079:16 per mile. Miles 9 through 11 stood out as his strongest stretch, ticking off splits of 8:55, 9:13, and 8:33 to push his cumulative pace to its fastest point of the day.
