  • Daniel Renteria won the M35-39 age group in 46:47 (7:32/mi), finishing more than 1:15 clear of runner-up David Quenzer.
  • Quenzer, Ayzenshtok, and Schneider packed into a tight 29-second window from 2nd through 4th, with just 4 seconds separating 3rd and 4th.
  • Ilia Ayzenshtok made the most dramatic move of the race, climbing from 51st to 33rd among men on the final stretch — the strongest late charge in the top five.
  • The top five all ran sub-7:51/mi pace in 74°F heat, with Austin Spikes rounding out the group in 5th at 48:42.

Daniel Renteria put together the most commanding performance in the M35-39 field, crossing in 46:47 at a 7:32/mi clip to claim the age-group title by 1 minute and 15 seconds. That margin wasn't close — it was a statement. Renteria also posted the 27th-fastest split among men on the 1M-to-finish stretch, showing he didn't coast to the line.

Behind him, the battle for the podium was a different story entirely. David Quenzer held 2nd at 48:02 (7:44/mi), but Ilia Ayzenshtok was charging hard. Ayzenshtok, making the trip from Atlanta, GA, had been sitting 51st among men at the one-mile mark and clawed all the way up to 33rd by the finish — the biggest mover in the top five. His 48:27 was good for 3rd, with Daniel Schneider of Fresno just four seconds back in 4th at 48:31. Both ran 7:48/mi averages, but it was Ayzenshtok's faster closing split that edged the gap. Austin Spikes completed the top five in 48:42, running 7:50/mi in conditions that made every second of that final push feel earned.

Jose Abundiz took 6th in 49:38 to close out the sub-50-minute contingent, while David Alaniz (7th, 52:34) and Steven Si (8th, 52:50) led a second wave across the line. Forty-eight men in all finished the M35-39 age group on a warm Fresno morning — a solid turnout for a race where the heat had a say in every finishing time.
