M55-59 Half Marathon: Amendt dominates while Celum and Duerksen stage a photo-finish duel for the silver

By MyRace AINovember 2, 2025
  • Joe Amendt (56, Clovis) won the M55-59 group in 1:28:41 — a 6:46/mi pace that put him more than 21 minutes clear of the rest of the field.
  • John Celum and Darren Duerksen both clocked 1:49:50 — same time to the second, with Celum edging 2nd and Duerksen taking 3rd by the finest of margins.
  • Sergio Arzate was just 25 seconds back of that pair in 4th at 1:50:15, making the 2nd-through-4th spread a tight 25 seconds across three men.
  • Amendt's second-half surge was decisive: he moved from 120th among men at 10K all the way to 26th among men by the finish, passing hundreds of runners over the back half.

Joe Amendt turned this into a one-man show. Running 6:46 per mile on a warm November morning in Fresno — 74°F and clear — he crossed in 1:28:41, a time that rendered the rest of the M55-59 group a separate race entirely. His movement through the men's field tells the story: 120th among men at the 10K checkpoint, 40th at the next marker, and 26th at the tape. That kind of sustained, progressive surge over 13.1 miles in the heat is the mark of a runner who ran his own race and ran it very well.

Behind Amendt, the real drama belonged to Celum and Duerksen. The two Clovis and Fresno locals — both 58 and 57 — finished in 1:49:50 apiece, with Celum claiming 2nd and Duerksen 3rd by a margin the clock couldn't display. Celum had the stronger back half, posting the 131st-fastest 10K-to-finish split among men, while Duerksen's 147th-fastest on that same segment tells you the gap was razor-thin all the way home. Sergio Arzate (56, Atwater) was right there too, finishing 4th in 1:50:15 — just 25 seconds separating three men across three podium spots.

The rest of the 33-man M55-59 field spread out from Manoj Khadka in 5th (1:54:51) through a cluster of sub-2:00 finishers — Marcos Martinez, Javier Hernandez, Alan Vong, Lance Little, Daniel Hernandez, and Silvester Kagunye all landing between 1:55 and 1:59:47 — before the field stretched past the two-hour mark. Thirteen more finishers rounded out the group beyond the top 20. It was a deep, competitive age group on a warm day, even if the winner made it look otherwise.
