F15-19: Kenzie Bailey Dominates Boston's Heat

• Bailey wins by 5:10 — her 37:33 finish at 6:03/mi was the clear class of the F15-19 field, and her second-half split ranked 25th among all women.
• Grant edges Holmes for 2nd — 42:43 to 43:19, a 36-second gap, with both runners posting strong closing legs to move up in the women's field.
• Chiu climbs hardest — Lauren Chiu's surge from 140th to 94th among women across the race was the most dramatic position gain in the top five.
• 84 finishers completed the F15-19 race on a sweltering 85°F morning in Boston.

With temperatures hitting 85°F and humidity at 64%, the B.A.A. 10K handed every runner a brutal test — and Kenzie Bailey, 18, from Georgetown, TX, answered it emphatically. Her 37:33, averaging 6:03 per mile, put more than five minutes between her and the rest of the F15-19 field. That margin wasn't just comfortable — it was commanding. She also had the legs to close, posting the 25th-fastest second-half split among all women in the race.

Behind Bailey, the battle for 2nd and 3rd was a genuine fight. Ada Grant (17, Longmeadow) and Johanna Holmes (18, N. Easton) both came alive in the final 2K. Grant moved from 80th to 70th among women to claim 2nd in 42:43, while Holmes — who started even deeper in the pack at 99th — charged to 76th and crossed in 43:19. Thirty-six seconds separated them at the line, with both clearly gaining momentum as the race wore on.

Lauren Chiu made perhaps the most eye-catching move of any runner in the age group. Starting the race 140th among women, the 19-year-old from Providence climbed all the way to 94th by the finish, a relentless progression across every checkpoint. Audrey Seeger (17, Chestnut Hill) rounded out the top five in 44:53, holding her position steadily through the second half. Further back, Camryn Rafuse and Hallie Robitaille crossed in identical times of 51:11 — though the official results separate them at 14th and 15th — a testament to how tightly bunched the middle of this competitive field was on a very tough morning.
