Napa Valley Marathon F30-34: Centner Defends, Battles Through to the Finish

• Ann Centner won the F30-34 field in 2:43:06 (6:13/mi) — one year after setting the women's course record here with her 2022 win (2:38:29).
• Lauren Ross led among women at the halfway mark before fading to 3rd among women by the finish, crossing in 2:45:58 — just 2:52 behind Centner.
• Sarah Gulli ran the 4th-fastest women's split on the final stretch (20M to Finish), climbing from 5th at halfway to 3rd in F30-34 at 2:51:12.
• Melissa Gioe was the race's great mover, surging from 14th among women at the opening checkpoint all the way to 10th by the finish (3:00:18, 6:53/mi) — posting the 10th-fastest women's second-half split in the field.

Ann Centner came back to Napa as the defending champion and the holder of the women's course record, and she made it a genuine title defense rather than a coronation. She didn't lead the women's race at every checkpoint — Lauren Ross of Portland grabbed the lead at the 10K mark and held it through the half, posting the fastest women's split on that opening segment. But Centner responded on the back half. She ran the fastest women's split from 13.1M to 20M, reclaimed the lead, and never surrendered it again, finishing in 2:43:06 at a 6:13/mi clip to win F30-34 and the women's race outright.

Ross, who had been so strong through the first half, couldn't quite hold on — she crossed in 2:45:58 for 2nd in F30-34, a gap of 2:52 to Centner. That's a clear catch-up story: Ross built an advantage in the first half, Centner erased it and then some in the second. Behind them, Sarah Gulli of San Francisco ran a quietly excellent back end, posting the 4th-fastest women's split from 20M to the finish and landing 3rd in F30-34 at 2:51:12. Estelle Richardson of Superior rounded out the top four at 2:54:50.

The most dramatic trajectory in the field belonged to Melissa Gioe of Belmont. She was 14th among women at the first checkpoint and still 11th at halfway — then she turned it on, running the 10th-fastest women's second-half split to finish 10th among women and 5th in F30-34 at 3:00:18. Nicole Zanardi (3:00:55) and Jennifer Tetrault (3:02:16) completed a tight cluster at the top of the middle pack, with all three finishing within two minutes of each other across positions 5 through 7 in the F30-34 standings.
