M40-44: Chelanga Dominates the 40s in Chicago

• Sam Chelanga won the M40-44 group in 1:03:52 (4:52/mi) — more than 6 minutes clear of 2nd-place Luke Baltrusch (1:10:00).
• Luke Baltrusch made a strong late move, climbing from 26th among men to 21st on the final stretch to lock up 2nd in M40-44.
• Ben Bocher rounded out the podium in 1:12:01, closing well with the 26th-fastest split in the men's field on the 15K-to-finish segment.
• Places 19 and 20 — Joel Clarke-Ames and Marcus Chiu — finished in identical displayed times of 1:26:17, with Clarke-Ames edging ahead by the slimmest of margins.

Sam Chelanga simply ran away from the M40-44 field. His 4:52/mi average would be remarkable in any age group, and across 595 finishers in the 40-44 bracket it was in a class of its own — the gap to Baltrusch alone was 6 minutes and 8 seconds. His position among the men's field barely wavered all race, hovering between 10th and 11th throughout, and he posted the 7th-fastest men's split on the 8K-to-10K segment. In comfortable 60°F conditions with a light breeze, Chelanga made Chicago look easy.

Behind the winner, the real story was Baltrusch's finishing kick. He ran most of the race in 25th–26th among men before surging to 21st on the final leg — enough to secure 2nd in M40-44 at 1:10:00 flat. Bocher held steady in 3rd, his 1:12:01 backed by a strong close from 15K to the finish. Villasenor Altamirano and Kyle Anderson filled 4th and 5th but faded noticeably in the back half, each slipping through the men's field across the final segments.

The pack from 6th through 20th was tightly bunched, with Sean Gill (1:22:13) through Marcus Chiu (1:26:17) covering eight places in just under four minutes. Clarke-Ames and Chiu provided the race's tightest finish among the listed runners — same clock time, different places, separated by a fraction of a second that only the chip knows for certain.
