San Francisco Marathon F20-29: Wolfrum Surges to the Front in the Final Miles

• Jenna Wolfrum, 24, wins the F20-29 race in 2:52:10 (6:34/mi), climbing from 10th among women at halfway to 1st by the finish — the only runner in the field to post the fastest women's split on the 6.52M–10.89M segment.
• Liana Eisler closes fastest, posting the 2nd-fastest women's split on the final stretch (24.69M to finish) to move from 20th among women at the gun to 7th, finishing 2nd in F20-29 at 3:05:59.
• Emily Jackson makes the biggest positional move, surging from 96th among women at the first checkpoint all the way to 18th by the finish (3:15:29, 7:27/mi), with the 2nd-fastest women's split on the 10.89M–Garmin Hill Challenge segment powering her climb.
• Charlotte Kinchla (3:38:29) and Sarah O'Shea (3:38:33) finished 11th and 12th respectively — four seconds apart after 26.2 miles.

Jenna Wolfrum ran a patient, calculated race through the foggy San Francisco streets. Sitting 10th among women through the early miles, she detonated on the 6.52M–10.89M segment — posting the fastest women's split on that stretch — and never looked back. By mile 19 she had climbed to 2nd among women, and by the finish she had claimed the top spot in F20-29 with a commanding 2:52:10, more than 13 minutes clear of runner-up Eisler.

Liana Eisler, 23, told a different story with her legs. She ran conservatively through the middle of the race but unleashed the 2nd-fastest women's closing split from 24.69M to the finish, reeling in runners ahead of her to land 2nd in F20-29 at 3:05:59. Emily Orellana (3rd, 3:11:47) was steadier throughout, holding roughly 10th among women from the first half onward and finishing with the 9th-fastest women's split on the opening half to secure the final podium spot.

The most eye-catching journey through the field belonged to Emily Jackson, 23, of San Francisco. Starting deep — 96th among women at the first checkpoint — she ran the 2nd-fastest women's split through the Garmin Hill Challenge segment and kept pressing all the way to 18th among women and 5th in F20-29 at 3:15:29. Samantha Burke (4th, 3:14:19) and Paige Koeven (6th, 3:16:58) rounded out the top six in a field of 228 finishers, all navigating the city's signature hills in cool, damp 56°F conditions.
