M15-19: Steven Dusseau Wins the Teen Battle in Boston's Heat

• Steven Dusseau, 15, takes the M15-19 title in 34:41 (5:35/mi), finishing 28 seconds clear of runner-up Nolan Harris.
• Podium sweep for the young guns: Dusseau (15), Harris (16), and Benjamin Habeski (18) covered the top three spots; the full top six finished within a 1:35 window.
• Collin Moore, also 15, rounds out the top five at 36:08 — impressive company for a teenager from Ocala, FL, racing in Boston heat.
• 87°F, 18 mph winds, and 66% humidity made this a genuine war of attrition across all 93 M15-19 finishers.

Running a steady 5:35 per mile through one of the tougher weather days Boston has seen for a June 10K, Steven Dusseau of Plymouth, MI handled the conditions as well as anyone in the M15-19 group. At just 15 years old, he moved from 58th among men at the 5K checkpoint to 51st by 8K and held that position to the finish — a controlled, progressive effort that left little room for doubt. His winning margin of 28 seconds over Nolan Harris was comfortable without being runaway.

Harris, a Newton local running on familiar ground, was actually moving well through the men's field early — sitting 49th among men at the 5K mark — before fading to 61st by 8K and holding there to the finish. His 35:09 was still a strong second-place showing. Habeski, meanwhile, told a different story: he started deep in the men's field at 87th and steadily climbed to 75th by the finish, making him one of the bigger movers in the group. That kind of progression in 87-degree heat is worth noting.

The gap from 3rd to 6th was tight — Habeski (35:42), Emery Young (35:54), Moore (36:08), and Wyatt Lee (36:16) were all within 34 seconds of each other, making for a genuine mid-pack battle. Ryan Costello and Andrew Carrier essentially raced to the same clock at 37:18 and 37:19, while Calum Gillies and Kenichi Gomi both clocked 39:25 further back. With 93 teenagers finishing on a brutally warm Sunday in Boston, the M15-19 group put on a quietly competitive show from front to back.
