F20-24 at CIM: Ava Nuttall Runs Down the Field for a 2:35 Win

• Ava Nuttall, 22, wins in 2:35:08 (5:55/mi) — the fastest in the F20-24 group among 134 finishers, climbing from 71st among women at the opening checkpoint to 3rd by the finish.
• Decisive mid-race surge: Nuttall posted the 2nd-fastest women's split from 15K to the half, the move that cracked the race open.
• Sofia Camacho's closing kick: Starting the race 133rd among women, Camacho rallied to finish 39th — her 19th-fastest women's split from 40K to the finish powered a 2:41:23 for second in F20-24.
• Madeline Block fades, Katherine Dowie charges: Block ran 9th among women early but slipped to 105th by the line (2:47:43); Dowie meanwhile climbed from 266th to 108th, with the 25th-fastest women's split from 35K to 40K, finishing just 14 seconds back in fifth.

Nuttall's race was a masterclass in patience and progression. She crossed the opening checkpoints outside the top 70 among women, then began picking off runners with surgical precision through the middle miles. That 15K-to-half split — second-fastest among all women on that stretch — was the turning point, vaulting her from 34th to 17th among women in one stretch and signaling she was in a different gear than anyone else in the F20-24 field. She never relinquished the lead from there, crossing at 5:55 per mile to win by more than six minutes.

The battle for second and third told its own story. Alexandra Ross (2:44:32, 6:17/mi) was a factor in the early going, posting the 15th-fastest women's split from 10K to 15K and sitting 42nd among women at the half — but she faded through the back half, eventually settling third in F20-24 at 68th among women. Camacho, meanwhile, was running an entirely different race: still 125th among women at 15K, she ground her way forward relentlessly and closed with one of the sharpest finishing splits in the women's field to claim second.

The most dramatic arc in the group may belong to Madeline Block, who opened at a 6:24/mi clip aggressive enough to put her 9th among women through the first 5K. The pace caught up with her — by 40K she had slipped to 101st among women — and she held on for fourth at 2:47:43. Dowie's mirror-image charge from 266th to 108th among women, finishing just 14 seconds behind Block, made for one of the sharpest contrasts in the F20-24 field: one runner who spent the whole race chasing, another who spent it trying not to be caught.
