M15-19: Nolan Mussatt Runs Down the Win in Chicago's Heat

• Nolan Mussatt took the M15-19 title in 1:30:30 (6:54/mi), nearly a minute clear of runner-up Sebastian Macias (1:31:27).
• The top four were separated by just 4:29, with Tyler Golod (1:34:59) rounding out a tight battle for the podium spots.
• Aleksander Saame and Marcos Chavez staged a thriller for fifth: two seconds apart at 1:38:40 and 1:38:42.
• All 41 finishers in the M15-19 group were listed at age 15 — a remarkably deep single-year cohort on a warm Chicago morning.

At 72°F with a 10 mph wind, the conditions were manageable but not fast, which makes Mussatt's 6:54/mi average all the more impressive for a 15-year-old. His race unfolded with a strong first half — he posted the 112th-fastest First Half split in the women's field, a useful benchmark that shows just how quickly he was moving through the broader race. He surged through the middle miles, climbing from 186th to 137th among women by the 8K mark, before settling into a controlled finish to seal the win.

Sebastian Macias ran a smart race of his own, peaking with the 101st-fastest 5K→8K split among women — his sharpest segment of the day — and holding on through the back half to claim second in 1:31:27. Samuel Amador closed the strongest of the top three, posting the 194th-fastest 15K-to-finish split among women to surge through the final stretch and lock up third in 1:34:25. Tyler Golod, meanwhile, faded slightly over the closing miles after a solid first half, finishing fourth in 1:34:59.

The race for fifth was the afternoon's most dramatic subplot. Saame and Chavez ran virtually in lockstep across 13.1 miles, separated by just two seconds at the line — 1:38:40 to 1:38:42. After that, the field spread out steadily, with Daniel Amador (7th, 1:41:36) and Daniel Becerra (8th, 1:42:01) leading a strong middle pack. Forty-one teenagers finished on a warm Chicago Sunday — a serious group, top to bottom.
