Masters Men 10K: Marzolf Blazes to the Win in Fresno Heat

• Sean Marzolf won the Masters Men race in 34:42 (5:35/mi), climbing from 8th to 1st among men in the final stretch to claim the title.
• Courtney Curtis followed in 36:10 (5:49/mi), finishing 2nd with a similarly aggressive late surge — but Marzolf's closing split was faster, making the gap a 1:28 margin at the line.
• Jason Lienau, 56, delivered one of the day's best moves: climbing from 38th to 10th among men on the final segment to land 3rd in 42:17 (6:48/mi).
• The 62-year-old duo of Robert Boshart (7th, 48:25) and Chris Fiorentino (8th, 49:00) stood out as the oldest finishers near the top of a 138-man field.

With 74°F and clear skies in Fresno, the Masters Men 10K was never going to be a day for easy pacing — and Sean Marzolf didn't treat it like one. The 42-year-old from Sanger ran 5:35/mi to finish in 34:42, entering the final mile segment outside the top ten among men before surging all the way to the lead. His closing split ranked 5th-fastest among men on that segment, which tells the whole story: Marzolf didn't just hold on — he hunted.

Right behind him, fellow 42-year-old Courtney Curtis of Fresno made a near-identical move, going from 10th to 2nd among men with the 6th-fastest closing split. The gap between them at the finish was 1:28 — a product of Marzolf's faster final mile, not a difference in racing strategy. Both men ran the same race; one just ran it a little harder when it counted most.

Third place went to Jason Lienau of Clovis, who at 56 turned in arguably the most dramatic positional climb of the day — from 38th to 10th among men — finishing in 42:17 at 6:48/mi. Brian Kiler (4th, 42:49) also moved well late, going from 22nd to 11th among men. Between Lienau and Kiler, the gap was just 32 seconds after 6.2 miles of racing.

Deeper in the field, the competitiveness of the Masters Men group held up well across 138 finishers. Graham Joyce, at 67, crossed in 52:44 (8:29/mi) to claim 18th — a reminder that this field rewarded grit at every age. From Marzolf's 34:42 up front to the full field of 138, the Masters Men gave Fresno a race worth watching from wire to wire.
