Men's Ultramarathon: Herrera Rewrites the Course Record, Runs 52.4 Miles in Under Six Hours

• Isidore Herrera wins in 5:54:52 — a 6:46/mi average across 52.4 miles, besting the prior men's record set by Tyler Rocha (6:09:05 in 2025) by more than 14 minutes.
• Tight podium, then a gap: Spencer Fluetsch (2nd, 6:03:34) and Mayank Goel (3rd, 6:04:47) finished within 73 seconds of each other — but more than 36 minutes behind the winner.
• Biggest move of the day: Connor Guerrero started 9th among the men and climbed all the way to 4th by the finish (6:41:24, 7:40/mi), posting the 4th-fastest first-marathon split in the process.
• Mayank Goel's weekend double: Goel finished 5th in the Saturday 5K before coming back to claim the ultramarathon podium — a serious feat of back-to-back racing.

Isidore Herrera, 36, from Ventura, CA, delivered one of the most commanding performances this race has seen in the editions we have on record. Running 6:46 per mile — sustained across a 52.4-mile course that crosses the Golden Gate Bridge and loops through Golden Gate Park twice — he finished more than nine minutes ahead of the runner-up and shattered Tyler Rocha's 2025 men's winning time of 6:09:05. The 59°F morning with a stiff 16 mph wind off the Bay was no obstacle; Herrera led wire to wire, holding the top men's spot from start to finish.

Behind him, Spencer Fluetsch (26, Merced) and Mayank Goel (34, Boulder) ran each other into the ground over the final stretch. Fluetsch crossed in 6:03:34 at 6:56/mi; Goel answered in 6:04:47 at 6:58/mi — just 73 seconds the difference after more than six hours of racing. Notably, Goel actually posted the fastest first-marathon split among the men, while Fluetsch was third on that same segment — meaning Goel ran the first half harder but Fluetsch made up enough time across the full race to hold second. That's a genuine catch-up story in a very tight podium.

Connor Guerrero's charge from 9th to 4th is the day's best subplot. The San Francisco local (fitting, given the home course) ran 6:41:24 — a 7:40/mi average — and posted the 4th-fastest first-marathon split to climb five places and lock down the final near-podium spot ahead of 22-year-old Jaden Trujillo (5th, 6:44:55). John Nickerson (6th, 6:47:49) rounded out the sub-6:48 group at 43 years old, making him one of the older men near the front of a 107-finisher field.

Goel's story deserves its own beat: he raced the Saturday 5K, placed 5th among the men there, then came back to stand on the ultramarathon podium. That kind of double — speed one day, 52.4 miles the next — is exactly the sort of thing that makes a race weekend memorable.
