F40-44: Nagel-Wallimann dominates, McElroy and Canizalez battle to the wire

• Doris Maria Nagel-Wallimann wins in 3:05:41 (7:05/mi), nearly 20 minutes clear of the field in a 157-finisher F40-44 race.
• Nicola McElroy (3:24:54) edges Corina Canizalez (3:25:29) for 2nd — just 35 seconds apart after 26.2 miles, with Canizalez making up the gap late via the 20th-fastest women's split on the 22M→24M stretch.
• Vladyslav Dergunov (4th, 3:27:56) ran the early miles near the front of the women's field before fading across the second half.
• Linda Amador (5th, 3:35:58) posted the 38th-fastest women's split on the 22M→24M segment, closing strongly to round out the top five.

Doris Maria Nagel-Wallimann, racing out of Hünenberg, made this one look commanding from the start. She ran a 7:05/mi average through San Francisco's hills and bay winds — a pace none of her F40-44 rivals could touch — and held as high as 5th among all women through the early miles before settling at 7th women's overall by the finish. Her 6th-fastest women's split on the 2M→4M segment signals she went out with intent and never let up. The gap to 2nd place? Nineteen minutes and thirteen seconds.

Behind her, the real drama unfolded between Nicola McElroy and Corina Canizalez. McElroy, of Berkeley, ran a patient race — moving from 51st among women at the 2-mile mark all the way to 35th by the finish at 7:49/mi. But Canizalez, from San Jose, was the one making noise late. Starting 78th among women, she steadily climbed through the field and then uncorked the 20th-fastest women's split on the 22M→24M stretch to close the gap significantly. She crossed in 3:25:29 — only 35 seconds behind McElroy — a genuine catch-up that nearly rewrote the podium order. McElroy held on, but it was close.

Fourth-place Vladyslav Dergunov (3:27:56, 7:56/mi) told a different story — starting 23rd among women and posting the 26th-fastest women's split on the early 8M→9.6M segment, but drifting back to 48th among women by the finish as the course took its toll. Linda Amador (5th, 3:35:58) was steady throughout before finishing with a flourish of her own on that same late 22M→24M stretch, claiming 5th in 8:14/mi pace. The rest of the top ten — Marie Rousseau (6th, 3:37:58) through Amber Stassi (10th, 3:43:15) — were separated by just over five minutes across five finishers, a tight cluster on a course that tests every one of them.
