Men's Napa Valley Marathon: Mason Frank Seizes the Lead and Never Looks Back

• Mason Frank wins in 2:17:55 — the fastest men's time at Napa Valley in the editions we have, eclipsing Andrew Bauer's 2:24:04 from 2018, and just 1:26 shy of the 1987 course record.
• The mid-race surge decided it all: Frank posted the fastest men's split from 10K to the half, moving from 2nd to 1st — a lead he never surrendered.
• Dan Nestor's closing kick: running the fastest men's split from mile 20 to the finish, Nestor climbed from 5th to 3rd, finishing in 2:23:01 to edge Brandon Krage (2:24:30) by 34 seconds after Krage had led early.
• Depth at the front: nine men broke 2:37, and 40-something Michael Oliva (2:40:36, 12th) and Adam Henderson (2:41:20, 13th) made the top 15 in a men's field of 720.

A cold, still March morning in Napa — 39°F, near-calm wind — set ideal conditions for fast racing, and the front of the men's field delivered. Brandon Krage came out boldest, holding 1st through the opening 10K, but Mason Frank had other plans. Frank uncorked the fastest men's split of the 10K-to-half segment, moving from 2nd into the lead and running away from the field at a 5:16/mi clip. By the half, the race for the win was effectively over.

Nicholas Tsotu was the closest pursuer throughout, running the second-fastest split on that same middle stretch and locking in 2nd place by the halfway point. He held it all the way to the tape in 2:22:27 — a composed, consistent effort that kept him clear of the late charges behind him. Krage, who had led early, faded to 4th in 2:24:30 as both Nestor and the clock caught him in the final miles.

The most dramatic late movement belonged to Dan Nestor. Running out of Boulder, Nestor was as far back as 6th at the half but unleashed the fastest men's split of the final 10K-plus stretch, reeling in competitors one by one to claim 3rd in 2:23:01. Bobby Peavey, also from Boulder, mirrored that late charge with the 3rd-fastest closing split to finish 5th in 2:26:52 — two Boulder runners making their presence felt exactly when it mattered most.
