Masters Women 5K: Kossar Dominates in the Fog

By MyRace AIJuly 26, 2025Official site ↗
  • Megan Kossar, 54, wins in 20:38 — a 6:38/mi pace that left the rest of the Masters Women field of 308 nearly four minutes behind.
  • Lydia Lacy takes 2nd in 24:32, holding off Melinda Cortessis (3rd, 25:04) and Delina Huang (4th, 25:18) in a tight three-way battle for the podium's lower steps.
  • Places 3 through 10 are separated by just 1:09 — from Cortessis's 25:04 to Katherine Swanson's 26:13 — making the mid-pack a genuine race within a race.
  • Clement Chin, 68, finishes 8th in 26:07 — the oldest athlete in the listed field and one of the most impressive results on the board.

Megan Kossar ran away with the Masters Women race from the gun, posting a 6:38/mi average through the damp, wind-whipped streets of San Francisco. At 54, she didn't just win — she won by 3:54 over the 2nd-place finisher, a margin that speaks for itself on a 5K course. The 56°F drizzle and 13 mph wind were the same for everyone, and Kossar simply operated at a different level, finishing in 20:38 while the rest of the 308-woman field was still working through the final mile.

Behind her, Lydia Lacy (2nd, 24:32) ran a composed 7:54/mi to secure the runner-up spot with a bit of breathing room over a tightly bunched chase pack. Melinda Cortessis (3rd, 25:04), Delina Huang (4th, 25:18), and Andrea Casson (5th, 25:27) were separated by just 23 seconds across three places — a real contest for the final podium positions. Lauren Kahn (6th, 25:53) and Kimberly Pittis (7th, 26:03) kept pressing, making places 3 through 7 a span of barely a minute.

The most eye-catching story outside the podium belongs to Clement Chin of Alameda. At 68, Chin ran 26:07 at an 8:24/mi clip to claim 8th — a performance that stands out in any company. Katherine Swanson (9th, 26:13) and Stephanie Peters (10th, 26:17) rounded out the top ten within four seconds of each other, capping a competitive back half of the top-10 that made the race interesting well beyond the winner's tape.
