M15-19: Seamus McDonough Runs Away with the Teen Title in Boston

• Seamus McDonough, 17, Homer, AK — won the M15-19 age group in 34:15 (5:31/mi), more than a minute clear of the field.
• Michael Sommese, 19, Chicago — runner-up in 35:18 (5:41/mi), 1:03 back; Michael Bohlke, 18 rounded out the podium in 37:37 (6:03/mi).
• Kyle Berkson, 15 — the youngest in the top five, finished 5th in 38:33 (6:12/mi) despite fading slightly through the middle stretch.
• Kenichi Gomi, 17 — the most notable mover in the top ten, climbing from 115th to 94th among women across the race's second half before finishing 4th in 38:10.

A 17-year-old from Homer, Alaska isn't the name you'd expect to dominate a field of 48 in Boston's summer heat — 77°F with a 12 mph wind — but Seamus McDonough made it look straightforward. His 34:15, averaging 5:31 per mile, put a full 63 seconds between himself and second place. That margin wasn't luck; he ran with enough control that his gender ranking actually dipped one spot mid-race before he settled back into his rhythm and held firm to the finish.

Michael Sommese (35:18) was a clear and comfortable second, with the gap back to Michael Bohlke (37:37) a more substantial 2:19 — meaning the real contest for the podium was between Sommese and the rest of the field, not between Sommese and McDonough. Bohlke posted the 78th-fastest split among women on the 8K-to-finish stretch, while Kenichi Gomi (4th, 38:10) ran the 59th-fastest split over that same closing segment — a strong finish that helped him climb from 115th to 94th in the women's standings across the back half of the race.

Kyle Berkson, the lone 15-year-old in the top five, deserves mention for simply being there. His 38:33 finish (6:12/mi) in conditions that favored no one was a solid effort, even if his middle segment — where he slipped from 94th to 101st among women — cost him a shot at Gomi. Behind the top five, the field spread out steadily: Luke McGillivray went 6th in 39:57, Andrew Lynch 7th in 40:45, and the group from 8th through 13th was tightly bunched between 41:10 and 42:55. Fellow Alaskan Theo McDonough — likely no coincidence sharing a surname with the winner — finished 19th in 48:22, rounding out the named finishers in a 48-strong age-group field.
