M50-54: De Simone Dominates Napa in 2:40

• Flavio De Simone (age 52, Boulder) won M50-54 in 2:40:02 at a 6:06/mi clip — more than 20 minutes clear of the field.
• Jon Erskine (age 52, Soquel) held 2nd in 3:00:34, with Paul Wakefield (54, Santa Rosa) and Sean Coady (53, San Francisco) separated by just one minute across 3rd and 4th.
• Simon Zarur (51, Guadalajara) ran the 75th-fastest men's split on the final stretch from mile 20 to the finish — the strongest closing leg among the top finishers — to move from 150th in the men's field at the 20-mile mark all the way to 114th by the line, vaulting to 5th in M50-54.
• 69 men finished in M50-54, with the top 20 ranging from 2:40 to 3:30.

Under cool, crisp Napa skies — 42°F and a light breeze — Flavio De Simone put on a masterclass from start to finish. The 52-year-old from Boulder ran 6:06 per mile across 26.2 miles, sitting 12th in the men's field through the first half and never wavering, holding that position through the finish. His 2:40:02 wasn't just a win — it was a statement, putting more than 20 minutes between himself and every other M50-54 finisher.

Jon Erskine (52, Soquel) claimed a clear 2nd in 3:00:34, though his race had a different arc: he sat 48th among men at the 10K mark but gradually faded to 72nd by the finish — a sign that the back half of the course extracted its toll. Behind him, Paul Wakefield (54, Santa Rosa) and Sean Coady (53, San Francisco) ran remarkably parallel races, finishing 3rd in 3:10:44 and 4th in 3:11:44 respectively, separated by just 60 seconds after 26.2 miles.

The most dramatic story in the top ten belonged to Simon Zarur (51, Guadalajara), who looked like he might fade into the mid-pack after sitting 150th in the men's field at both the 10K and the halfway point. Instead, he uncorked the 75th-fastest men's split on the final 6.2-mile stretch, climbing from 133rd at mile 20 to 114th at the line — and 5th in M50-54 in 3:12:27. James Obrien (51, San Francisco) finished just seven seconds back in 6th at 3:12:34, making for one of the tighter battles of the day.
