M40-44 at the B.A.A. 10K: Ryan Irwin Runs Away With It

• Ryan Irwin won the M40-44 group in 32:48 (5:17/mi), finishing more than a minute clear of runner-up Chris Ritchie.
• Chris Ritchie held 2nd in 33:50, while John Colavincenzo climbed steadily through the men's field to claim 3rd in 35:09.
• The top-20 spread across a 434-runner M40-44 field covered nearly 8 minutes — from Irwin's 32:48 down to Nikhil Avasthi's 40:59.
• Three men at positions 8, 9, and 10 — Lopez-Oliveros, Jones, and Lemtukei — finished within four seconds of each other (38:29, 38:30, 38:33).

Ryan Irwin made the 87-degree Boston heat look almost routine. The Newton 40-year-old ran 5:17 per mile from start to finish, and his position among the men's field barely flickered all race long — he was 31st among the men at the 5K checkpoint and was still 31st at the line. That kind of locked-in consistency is the mark of a runner who knew exactly what he had and spent every bit of it evenly.

Chris Ritchie of Stratham held 2nd through the first two checkpoints before drifting slightly in the men's standings late, but the gap to Irwin — over a minute — never looked bridgeable. John Colavincenzo told a more dynamic story: the Wellesley 43-year-old was 74th among men at the first checkpoint, worked up to 65th by 8K, and finished 62nd, steadily reeling in runners through the second half to lock up 3rd in 35:09.

Eder Da Silva ran a strong early race — sitting 73rd among men through 5K — but faded slightly over the final stretch, finishing 4th in 36:10. JP Gerald rounded out the top five in 37:14. Behind them, the mid-pack produced one of the race's tightest clusters: Luis Lopez-Oliveros, Bernard Jones, and Marko Cheseto Lemtukei crossed in 38:29, 38:30, and 38:33 respectively — three men separated by just four seconds after 6.2 miles in oppressive heat.
