San Francisco Marathon 5K — Women's 70–74: Ahn claims the crown in the City by the Bay

• Jong Young Ahn, 70, wins in 41:25 (13:20/mi), finishing a full minute ahead of runner-up Maggie Mount's 42:25.
• Mount, 74, holds second despite a slight slip in the women's standings on the back half, crossing in 42:25 — more than 10 minutes clear of third place.
• JoAnn Florendo and Nancy Lombardo battled through the second half, finishing 3rd (52:51) and 4th (54:00) — separated by just 1:09 at the line.
• Judy Thomas, 70, rounded out the six-woman field in 1:07:08 (21:36/mi), completing the course on a breezy San Francisco morning.

Jong Young Ahn of Bellevue, WA, made this one look like a controlled exercise in pacing. Running 13:20/mi across the 5K, she steadily moved through the women's field, climbing from 695th to 633rd among women on the back half — a gain of 62 spots. Her 567th-fastest women's split on the 2.5K-to-finish stretch confirmed she was still pressing in the closing stretch, and her winning margin of exactly one minute over second place left no drama about who was in charge.

Maggie Mount, 74, from Fate, TX, earned a strong second-place finish at 42:25 (13:39/mi), though the final 2.5K was a slight struggle relative to the field — she slipped four spots in the women's standings from 661st to 665th, and her 662nd-fastest women's split on that closing segment was noticeably slower than Ahn's push to the tape. Still, Mount's runner-up finish at 74 years old in windy, 60-degree San Francisco conditions is a genuine achievement in this field.

Behind them, the race for the podium's bottom step played out between two San Francisco Bay Area locals. JoAnn Florendo, 70, of San Francisco, crossed in 52:51 (17:01/mi) for third, while Nancy Lombardo, 73, of Lakewood, CA, finished fourth in 54:00 (17:23/mi). The 1:09 gap between them was the tightest margin of the day, though Lombardo actually ran the 2.5K-to-finish segment slightly better by the rankings — her 905th-fastest women's split edged Florendo's 915th. Linda Keaton, 72, of Stockton, CA, took fifth in 57:11 (18:24/mi), closing strongly enough to move up 13 spots in the women's field over the back half.
