San Francisco Half Marathon 2024: Qi Lu Runs Away with the F45-49 Title

• Qi Lu wins in 1:43:33 (7:54/mi), finishing 4:29 clear of runner-up Crystal Culhane — a dominant margin in a 152-runner field.
• Podium spread: Culhane 2nd in 1:48:02, Cynthia Mercede 3rd in 1:49:00 — just 58 seconds separating 2nd from 3rd.
• Places 4–7 in a 2-minute cluster: Julia Mallon (4th, 1:50:53), Alicia Morales López (5th, 1:50:59), Sophie Viaud (6th, 1:51:01), and Melanie Tremblay (7th, 1:51:05) — 12 seconds covering all four.
• Biggest mover: Morales López started 150th among women and climbed steadily to 117th by the finish, logging the 122nd-fastest women's split on the 7.12M–10.65M stretch to fuel her charge.

Qi Lu made this race look controlled from start to finish. Running at a 7:54/mi clip through the hills of San Francisco, the Milpitas 45-year-old moved from 56th among women at the first checkpoint all the way up to 44th by the end — and held that position through the final miles. Her strongest segment came in the 7.12M–10.65M stretch, where she posted the 37th-fastest women's split in the field, a surge that effectively sealed the win. At 1:43:33, she finished nearly four and a half minutes ahead of second place, the clearest statement of superiority in this entire race.

Crystal Culhane ran a steady race from San Diego, sitting 67th among women through the early miles and finishing 75th — a consistent if unspectacular position — but her 8:14/mi pace was good enough for a comfortable 2nd-place finish in 1:48:02. Cynthia Mercede of New Canaan was the story of the back half, posting the 80th-fastest women's split on the 10.65M-to-finish leg to close hard and secure 3rd in 1:49:00. She had dropped as deep as 111th among women at the midrace checkpoint, making her final podium spot a genuine late push.

The most entertaining subplot was the four-way scramble for 4th through 7th. Mallon, Morales López, Viaud, and Tremblay finished within 12 seconds of each other — all clocking 1:50:53 to 1:51:05 at an 8:28/mi average. Mallon had led the group early, sitting 49th among women at the first check, but faded to 114th by the finish. Morales López, meanwhile, made the opposite journey, climbing from 150th among women all the way to 117th. The story of the race's middle tier was a slow-motion swap that ended in a near-dead-heat.
