By MyRace AIJuly 26, 2026Official site ↗
  • Mariel De La Jara-Smith took the win in 2:00:44 (9:13/mi), posting the fastest non-binary split on the 8M→9.6M segment.
  • Ara Warren crossed in 2:19:53 (10:40/mi), clocking the 5th-fastest non-binary split on the 4M→6M stretch.
  • A 19-minute, 9-second gap separated the two finishers at the line.

Mariel De La Jara-Smith, 19, from San Francisco, controlled this race from the opening miles. Holding 2nd in the non-binary gender standings through the early checkpoints, De La Jara-Smith settled into a steady 9:13/mi rhythm and delivered the fastest non-binary split on the 8M→9.6M segment — a clear sign of strength in the race's middle miles. Despite some shuffling in the gender standings through the back half, De La Jara-Smith held firm to finish 1st in the under-19 field and 3rd among non-binary competitors overall, crossing in 2:00:44.

Ara Warren, 18, from Vacaville, brought a different kind of energy to the early going. Warren posted the 5th-fastest non-binary split on the 4M→6M segment, showing genuine pop in those miles, and held a steady position in the gender standings through mid-race. The back half proved tougher — Warren's gender place slid from 6th to 9th over the final miles — but the 18-year-old saw it through to the finish in 2:19:53 at a 10:40/mi pace, a solid result for one of the youngest competitors on the course.

With only two finishers in the under-19 field on a breezy San Francisco morning, every mile counted. De La Jara-Smith's 19-minute cushion at the line reflects consistent pacing from start to finish, while Warren's strong 4M–6M split hints at real potential as the miles and experience accumulate.
