Half Marathon NB55-59: De Loza Goes the Distance Solo

• Sole finisher: Javier De Loza, 58, of Cotati, CA, completed the NB55-59 field in 2:34:57 (11:49/mi avg).
• Best segment: De Loza posted the 7th-fastest women's split on the 8M→9.6M stretch — a standout effort on that leg.
• Steady presence in the men's field: He moved from 20th to 18th among the men by the second checkpoint and held that position through the finish.

Javier De Loza owned the NB55-59 race from start to finish — because he was the only one in it. That's not a knock; showing up and covering 13.1 miles through San Francisco's famously rolling terrain, in 14 mph winds and 78% humidity at 59°F, takes real commitment at any age.

De Loza ran a measured 11:49/mi pace to clock 2:34:57, and the most telling detail of his day came between miles 8 and 9.6. On that stretch, he turned in the 7th-fastest split among all women on that segment — meaning he was moving with genuine purpose when it counted, not just grinding to the finish. He also climbed from 20th to 18th in the men's field by the second checkpoint and never ceded that ground the rest of the way.

The NB55-59 title is his, uncontested but fully earned on a blustery San Francisco morning.
