San Francisco Half Marathon: Alberto Campos Owns the 19-and-Under Field

• Sole finisher in the 19-and-under race, Alberto Campos, 15, crossed in 2:46:09 at a 12:40/mi pace.
• His strongest segment came on the 2.13M→6.43M stretch, where he posted the 6th-fastest split among the men on that portion of the course.
• He moved from 8th to 5th among men at his peak, before settling to 6th at the finish.

Alberto Campos of Indio, CA was the only finisher in the 19-and-under race at the 2023 San Francisco Half Marathon, which meant the title was his to claim — but the 15-year-old still had to earn it over 13.1 miles of San Francisco's demanding terrain, under overcast skies with 87% humidity pressing down on the field.

What made Campos's run genuinely interesting wasn't the uncontested title — it was how he moved through the broader men's field. He entered the 2.13M→6.43M segment sitting 8th among the men, and on that stretch he turned in the 6th-fastest men's split of anyone in the race, a sharp middle-miles push that vaulted him as high as 5th. He couldn't quite hold that position all the way home, finishing 6th among the men at 2:46:09, but the fact that a 15-year-old was trading places with the broader men's field speaks for itself.

At 12:40 per mile over a hilly San Francisco half marathon course, Campos crossed the line as the undisputed 19-and-under champion — the only one willing to show up and race it.
