Women's Half Marathon: Greenwood surges late to claim San Francisco

• Sarah Greenwood wins in 1:21:47 (6:14/mi), posting the fastest women's split on the final 10.9M–Finish stretch to move from 5th to 1st in the closing miles.
• Yuzuki Oey (1:25:10) and Jessica Nunez (1:25:47) both ran the 2nd- and 3rd-fastest second-half splits among women, catching and passing rivals to lock up 2nd and 3rd on the podium.
• Kurstin Kalisek (12th, 1:31:27) had already raced to 2nd among women in the Saturday 5K — backing that up with a 6:59/mi half is a standout weekend double.
• Hannah Ryan (19th, 1:33:02) returns to the San Francisco Half having finished 6th here in 2022 (1:27:19), a notable regression of nearly six minutes.

Through the first 10.9 miles, Sarah Greenwood of Osborne Park sat patiently in 5th among women — close enough to strike, but not yet showing her hand. Then she unleashed the fastest closing split of any woman in the 1,632-finisher field, reeling in the leaders and crossing in 1:21:47 at a 6:14/mi average. It was a textbook negative-split execution on a cool, overcast San Francisco morning, and it delivered the win by more than three minutes over the runner-up.

Behind Greenwood, the second half of the race was a battlefield. Yuzuki Oey (San Carlos, CA) and Jessica Nunez (Oakland, CA) both sat in 7th and 6th respectively through the midpoint, then each unleashed blistering closing legs — the 2nd- and 3rd-fastest second-half splits among the women — to climb to 2nd (1:25:10, 6:30/mi) and 3rd (1:25:47, 6:33/mi). Rebecca Wheeler (4th, 1:27:33) and Hannah Tecott (5th, 1:28:20) also moved up steadily through the field, with Tecott posting the 5th-fastest second-half split among women at 6:44/mi. The top five all arrived having passed multiple competitors — this was a race won and placed in the back half.

Further down the leaderboard, Erin McDonald (6th, 1:28:39) and 21-year-old Sierra Williams (7th, 1:29:24) rounded out a competitive top ten, with Daisy Williamson (8th, 1:30:54), Sarah Nelson (9th, 1:30:58), and Martina Festoli (10th, 1:31:00) separated by just six seconds across three places. Kurstin Kalisek's 12th-place 1:31:27 capped a remarkable weekend — she'd already stood on the podium in the Saturday 5K, and came back the next day to run sub-7:00 pace for 13.1 miles.
