Boys U-19 at the SF Marathon 10K: Hupke Laps the Field

• Jacob Hupke, 17, ran 32:58 (5:18/mi) — winning the U-19 boys by a commanding 4 minutes and 42 seconds over 2nd place.
• Nico Navarro (37:40) and Nathan Jay (38:07) completed the podium, separated by just 27 seconds after 6.2 miles.
• 14-year-old Zephyr Rhew finished 5th in 44:04, the fastest among the youngest competitors in the field.
• Dash Jorgensen, age 12, crossed in 56:33 — the youngest finisher in the listed results, completing a full 10K on the fog-cooled streets of San Francisco.

Jacob Hupke didn't just win the U-19 boys — he ran in a different race entirely. The 17-year-old from San Leandro posted a 32:58 at 5:18 per mile, a pace that left every other young runner in the field well behind. His margin of victory over 2nd-place Nico Navarro was 4 minutes and 42 seconds — a gap that tells you everything about how dominant his morning was across 55°F, fog-draped San Francisco.

Behind Hupke, the real competition was between Navarro and Nathan Jay. The 16-year-old from South San Francisco ran 37:40 (6:04/mi), while Jay, 17, of Fremont came in at 38:07 (6:08/mi). That 27-second gap at the finish is tight enough to make the podium genuinely interesting. Sean Macdonald rounded out the top four in 40:37, running 6:32/mi — a solid effort, though he finished more than two minutes behind Jay.

The depth of the field brought some compelling storylines further back. Berkeley's 14-year-old Zephyr Rhew ran 44:04 to take 5th, followed closely by fellow Berkeley teen Dante Johnson (15) in 45:02 — two young runners from the same city pushing each other through the second half of the race. And Dash Jorgensen, just 12 years old and from Clovis, finished 18th in 56:33 — a remarkable effort in a field of 63 that stretched all the way to the finish line.
