SF Half Marathon F50-54: Dulchinos Runs Down the Win in 1:50:14

• Alexandra Dulchinos topped the F50-54 field in 1:50:14 (8:25/mi), nearly a minute clear of runner-up Martina Steffen.
• Steffen finished 2nd in 1:51:06 (8:29/mi) — the two leaders ran well clear of a 3rd-place finisher nearly nine minutes back.
• Helen Molloy and Catherine Jude staged a tight battle for the final podium spot, finishing 3rd and 4th in 1:59:03 and 1:59:36 — just 33 seconds apart.
• Joanie Loh rounded out the top five in 2:02:34, posting the 260th-fastest women's split on the 2.95M–5M stretch — a bright early segment in her race.

Alexandra Dulchinos of Newton, MA ran the most dynamic race at the front of the F50-54 field. She entered the middle stretch — from mile 5 to mile 10.9 — sitting 110th among women, then surged to 91st on that segment, posting the 90th-fastest women's split across that stretch. She faded slightly to 98th by the finish line, but the damage was done: her 8:25/mi average held up for a convincing win in 1:50:14 on a cool, humid San Francisco morning.

Martina Steffen of Los Altos Hills, CA gave chase but couldn't match Dulchinos's mid-race surge. Steffen ran a steadier, more conservative line — her gender position drifted from 96th to 107th across the race — and her 109th-fastest women's split on the 5M–10.9M segment tells the story of the gap between them in that decisive phase. She crossed in 1:51:06, good for 2nd, but Dulchinos had already built the cushion she needed.

Behind the top two, the race for the podium was genuinely gripping. Helen Molloy, running her home city's course, held off Oakland's Catherine Jude by just 33 seconds — 1:59:03 to 1:59:36. Jude actually ran the 145th-fastest women's split on the final 10.9M-to-finish leg, clawing back ground late, but Molloy had enough of a buffer to claim 3rd. The remaining 65 finishers stretched out across a deep field, with Tracy Mora (10th, 2:11:31) and Jenny Winter (12th, 2:13:16) among those adding to a strong showing across all 70 F50-54 finishers on the roads of San Francisco.
