M55-59 Half Marathon: Williams Runs Away from a Deep Napa Field

• Jason Williams won M55-59 in 1:28:17 (6:44/mi), finishing more than four minutes clear of second place.
• Mike Mcmonagle held second in 1:32:40 (7:04/mi), while Bill Salacuse and Michael Bourquin staged a photo-finish battle for the final podium spot — separated by just two seconds (1:35:15 vs. 1:35:17).
• Weiming Wu ran the stronger second half to claim 5th in 1:36:09, overtaking James Semien (6th, 1:36:11) — a two-second gap that Wu earned by running the 6.9M→Finish segment faster than Semien, moving up 13 spots among men while Semien held steady.
• 63 men finished in M55-59, with the top 20 all breaking 1:52.

Jason Williams made the M55-59 race look almost uncomplicated in the 41°F Napa morning. Running at 6:44/mi, he built a lead that only grew as the miles went on — his 60th-fastest men's split on the 6.9M-to-finish stretch confirmed he wasn't just coasting to the tape. By the end, his 1:28:17 stood more than four minutes above anyone else in the field, a margin that speaks for itself across 13.1 miles.

Behind him, Mike Mcmonagle secured second in 1:32:40 at 7:04/mi, running a notably slower second half than Williams — a gap that widened rather than closed. The real drama of the day played out one place lower: Bill Salacuse (1:35:15, 7:16/mi) and Michael Bourquin (1:35:17, 7:16/mi) finished within two seconds of each other for 3rd and 4th. The timing finer than the displayed clock separated them — Salacuse edged ahead, but it was as close as racing gets.

Fifth place brought another compelling subplot. Weiming Wu came into the final stretch ranked 131st among men but surged to 118th by the finish — the 119th-fastest men's split on that closing segment — enough to pip James Semien by just two seconds (1:36:09 to 1:36:11). Semien, who faded slightly in the men's standings over the same stretch, will know Wu earned that place by running him down. From there, Thomas Wetter (7th, 1:38:20) through Paul Martino (10th, 1:41:18) kept the field tightly bunched, with just under three minutes separating positions 7 through 10.
