M40-44 at the B.A.A. 10K: Parkhurst Dominates in the Boston Heat

• Sherwin Parkhurst won the M40-44 group in 33:06 (5:20/mi), pulling away from runner-up Ryan Irwin by 41 seconds in 93°F heat.
• Places 4–6 finished within 4 seconds of each other — Trent Montgomery (35:10), Ryan Collins (35:13), and Chris Ritchie (35:14) — making that stretch the most compressed battle of the day.
• John Colavincenzo, at 44, claimed 3rd in 35:06, edging Montgomery by just 4 seconds despite being the oldest man on the podium.
• 392 men finished in M40-44, making it one of the deepest fields in the race.

Sherwin Parkhurst of Yarmouth, ME, turned in a commanding performance under brutal conditions — 93°F, a 15 mph wind, and Boston's unforgiving June sun. His 33:06 at 5:20/mi was in a class of its own in the M40-44 group, and his closing split told the story of a runner who got stronger late: he posted the 26th-fastest split on the 8K-to-finish stretch among all men, a sharp move that put the result beyond doubt.

Ryan Irwin of Newton ran a controlled 33:47 to hold 2nd from start to finish — his men's place barely budged across the race (39th among men at 5K, 39th at 8K, 39th at the line), a portrait of metronomic consistency. Irwin's 5:26/mi average in those conditions is no small feat, and the 41-second gap to Parkhurst reflects just how dominant the winner was rather than any fade from Irwin himself.

The real drama unfolded just off the podium. John Colavincenzo — the oldest of the top five at 44 — worked his way through the men's field across every checkpoint, moving from 59th among men at 5K to 54th at the finish. He crossed in 35:06, only to find that Trent Montgomery, Ryan Collins, and Chris Ritchie were all within 4 seconds of him, a four-man cluster compressed by the heat and the effort of the final stretch. Collins and Ritchie both clocked 5:40/mi; Montgomery was right there too. In a race this hot, holding that pace through the finish was an achievement in itself.
