M20-29: Derek Fearon Storms the Back Half to Claim the Title

• Derek Fearon, 2:35:14 (5:55/mi) — won M20-29 in a field of 648, posting the fastest men's split on the 22M→24M segment and charging from 20th among men at the opening checkpoint to 7th by the finish.
• Liam Bush, 2:36:21 — runner-up by 1:07, the steadiest mover of the top three, holding between 10th and 12th among men across nearly every checkpoint.
• Ryan Kachnowski, 2:38:19 — 3rd, fueled by the 8th-fastest men's split on the 6M→8M segment; rocketed to 8th among men at the second checkpoint before gradually settling back to 14th.
• Spots 6–9 compressed into 2:02 — Walter Chang (2:48:50), Richard McManus (2:49:50), Aidan O'Connor (2:49:53), and Vianey Ellison (2:50:12) finished in a tight cluster, with McManus and O'Connor separated by just three seconds.

Derek Fearon did not arrive at the front quietly. Sitting 20th among men through the early miles, the 24-year-old from Washington, DC ground his way forward checkpoint by checkpoint — 17th, 17th, 16th, 15th — before an explosive 22M–24M stretch, the fastest men's split on that segment, vaulted him to 7th among men at the line. In M20-29 specifically, that late surge was decisive: a 5:55/mi average over 26.2 miles through San Francisco's wind and hills is a performance that held up against a 648-runner field.

Liam Bush, the 23-year-old from SF itself, was the picture of consistency. He ran between 10th and 12th among men for virtually the entire race, backed by the 7th-fastest men's split on the 10.5M→12M segment, and crossed in 2:36:21 — 1:07 behind Fearon. It's a result that rewards patience and evenness over drama. Ryan Kachnowski was the opposite story: the Wixom, MI runner lit up the 6M–8M segment (8th-fastest men's split) to surge to 8th among men by the second checkpoint, but couldn't sustain that position, drifting to 14th among men by the finish while still claiming 3rd in M20-29 at 2:38:19.

Kaelen Ruder (4th, 2:42:35) and Ian Horsburgh (5th, 2:46:09) rounded out the top five, with Ruder also flashing early speed — 11th-fastest men's split on 6M–8M — before fading to 20th among men by the finish. Further back, the race at spots 6 through 9 was a story unto itself: two full minutes covered four runners, with 20-year-old Walter Chang of Fremont the youngest of the group at 6th (2:48:50), and McManus, O'Connor, and Ellison filing in within 22 seconds of each other between 2:49:50 and 2:50:12.
