SF Marathon 5K — F60-64: OHara Dominates in Dominant Fashion

• Katie OHara, 1st — 30:44 (9:54/mi), nearly three minutes clear of the field
• Min Chang, 2nd — 33:35 (10:49/mi); Gangzhen Zhang, 3rd at 35:41 (11:29/mi)
• Tightest battle of the day: Eileen Chen (10th, 48:11), Iris Wong (11th, 48:12), and Monica Ordonia (12th, 48:14) — three runners separated by just three seconds
• 22 finishers completed the F60-64 race, spanning from 30:44 to nearly an hour

Katie OHara of Redwood City set the tone from the start and never let up. Her 30:44 finish at 9:54 per mile was a commanding performance — nearly three minutes faster than anyone else in the F60-64 field. At 62, she owned this race outright, and the gap she built speaks for itself.

Behind her, Min Chang (33:35) and Gangzhen Zhang (35:41) locked in a solid top three, with Chang running 10:49/mi to Zhang's 11:29/mi — a meaningful pace difference that kept second place secure. Joanne De Castro followed in 4th at 36:29 (11:45/mi), rounding out a clear lead pack before a significant time gap opened to 5th-place Eiko Shirakawa, who crossed in 42:58 (13:50/mi).

The mid-pack drama belonged to the trio of Eileen Chen, Iris Wong, and Monica Ordonia. Chen crossed 10th in 48:11, Wong 11th in 48:12, and Ordonia 12th in 48:14 — three women, three seconds, three places. That's a genuine photo-finish cluster in a 5K, and all three earned it on a breezy San Francisco morning with 15 mph winds and 70% humidity adding friction to every stride.

The back half of the field showed the true range of this group. Béatrice Duffaud-Thiriet (15th, 51:51) made the trip count — all the way from Rochemaure, France — while Saroj Choudhary wrapped up the individually listed finishers in 20th at 59:57 (19:18/mi), just shy of the hour mark. Twenty-two women showed up to race San Francisco's hills and wind in their seventh decade. That's the real story.
