Masters Women 10K: Williams dominates in dominant fashion on the Bay

• Tiffani Williams, 49, wins in 40:29 (6:31/mi) — more than 5 minutes clear of the field and the 4th-fastest closing split among all women.
• Liz Guerrini, 56, takes 2nd in 45:44 — the oldest athlete on the podium, moving up three spots in the women's field over the final 4.62 miles.
• Junaline Gines (3rd, 46:02) and Karman Guadagni (4th, 46:30) ran nearly identical races through the finish, separated by just 28 seconds across a 522-woman field.
• Cherry Ann Weber (5th, 47:06) was the only top-five finisher to lose ground in the women's field on the closing stretch, slipping five spots to 29th among all women.

On a cool, damp San Francisco morning — 57°F and 93% humidity hugging the course — Tiffani Williams of Los Angeles ran a race in a class of its own. Her 40:29 at 6:31/mi wasn't just a win; it was a statement, putting 5 minutes and 15 seconds between herself and the rest of the Masters Women field. She held 5th among all women from start to finish, and her closing leg was the 4th-fastest women's split of the day — a sign she wasn't just managing a lead, she was still pressing.

Behind Williams, the real drama unfolded in the chase pack. Liz Guerrini, 56, ran a composed and intelligent race, picking off three women in the women's field over the final stretch to claim 2nd in 45:44 (7:22/mi). Junaline Gines, 41, followed in 46:02, with Karman Guadagni, 43, just 28 seconds back in 4th at 46:30 — both holding their positions through a tight, competitive finish. Guerrini's 12th-fastest women's closing split and Gines's 17th helped them both move up; Guadagni's 20th-fastest was enough to hold ground as well.

Fifth-place Cherry Ann Weber, 51, crossed in 47:06 but was the one podium-adjacent finisher who couldn't hold her early position, fading from 24th to 29th among all women on the closing leg. Victoria Woo (6th, 47:51) and Chrystal Keller (7th, 49:05) rounded out a competitive top seven before a dense cluster of finishers — from Sviatlana Chebatar's 8th-place 50:43 through Andrea Frisk's 17th-place 52:14 — packed into less than 90 seconds across ten athletes. In a field of 522, that mid-pack compression made every second count.
