Men's Race: John Korir Storms Past Yimer to Claim Boilermaker Glory

• Korir wins in 42:11, just 5 seconds off Jemal Yimer's 2023 course record of 42:06 — the fastest the Boilermaker men's race has been run since that record was set.
• Yimer finishes 2nd in 42:19, eight seconds back, defending his title from 2023 (and 2022) — but unable to hold off Korir's decisive mid-race surge.
• Wesley Kiptoo takes 3rd in 43:13, a full minute behind Korir and 1:02 clear of 4th-place Yemane Hailesellassie (43:22).
• Sam Morse, 40, runs 47:14 to lead the chase pack well clear of the next two finishers, Jorge Castelblanco (47:28) and Scott Loforte (47:29).

The 2024 men's race at the Boilermaker 15K had the feel of a chase from the very start — and the story of how John Korir hunted down a two-time defending champion is the headline. Through the opening 5K, Korir sat 22nd among the men, while Yimer was already up in 17th. But between 5K and 10K, Korir posted the fastest split of anyone in the field on that segment, rocketing from 22nd all the way to 3rd. Yimer's 5K→10K split was the second-fastest in the field — he was flying too — but Korir was flying faster.

By the 10K mark, Korir had moved to 3rd, Yimer to 2nd, and the race was set up for a dramatic final push. Over the closing 5K, Korir completed the move, surging past to take the win in 42:11 while Yimer held 2nd at 42:19. Jemal Yimer came to Utica as the defending champion and course record holder — and he ran a race worthy of that reputation — but on this day, Korir was simply stronger when it mattered most.

Wesley Kiptoo (43:13) rounded out the podium in 3rd with the third-fastest 5K→10K split in the field, while Yemane Hailesellassie (43:22) posted the third-fastest closing segment to lock up 4th. Boniface Kibiwott (43:26) and Edmond Kipngetich (43:35) completed a dominant top six, all finishing within 84 seconds of the winner across a field of 4,466 men. Further back, Matthew Baxter (45:05) was the last man under 4:51/mi, and Andrew Bowman (45:47) led a tightly bunched group from 13th through 15th — Afewerki Zeru and Tristan Woodfine both clocking 45:56.
