M45-49: Abdi Abdirahman Runs Away With It in Chicago's Heat

• Abdi Abdirahman won M45-49 in 1:06:15 (5:03/mi), finishing more than 11 minutes ahead of runner-up Nicolas Delgado (1:17:45).
• Delgado climbed from 51st to 43rd among men across the race, logging the 42nd-fastest split in the men's field on the 10K–15K stretch.
• Places 4 and 5 were decided by a single second: Jose Ramirez-Guadarrama (1:23:49) edged Jacobus Wijpkema (1:23:50) — same displayed time, different finish.
• Wijpkema was the biggest mover in the top five, surging from 129th to 101st among men across the race.

Abdi Abdirahman simply ran a different race than the other 332 men in M45-49. On a warm Chicago morning — 79°F, 20 mph winds, and the kind of humidity that makes a 5:03/mi average feel every bit as hard as it sounds — the Tucson native posted a time that would have been remarkable at any age. His margin of victory wasn't a photo finish or a late surge; it was a sustained, 13.1-mile statement.

Behind him, Nicolas Delgado of Chicago ran a disciplined second. His 1:17:45 at 5:56/mi was a strong performance in its own right, and his steady climb through the men's field — moving from 51st to 43rd — showed he was getting stronger as the race wore on. Carlos Spallanzani of León, Guatemala, rounded out the podium in 1:22:06, closing with the 67th-fastest split in the field on the final 15K-to-finish stretch to hold off a tight pack behind him.

That pack made for the most dramatic racing of the day in M45-49. Ramirez-Guadarrama and Wijpkema were essentially inseparable at the finish — one second separating 4th from 5th — but Wijpkema's race trajectory was the more eye-catching: he entered the back half of the race in 129th place among men and finished 101st, a charge of 28 spots. It wasn't quite enough to catch Ramirez-Guadarrama, but it made for a compelling final few miles in a group race that extended well beyond the top 20 across a 333-finisher field.
