SF Marathon Half: Rosaldo Owns NB45-49

• Jesus Rosaldo finished in 2:37:49 — the sole finisher in NB45-49, and the only one who needed to be.
• Averaged 12:02/mi across the 13.1-mile course through San Francisco.
• Logged the 15th-fastest women's split in the field on the 6.62M→7.12M segment — a half-mile stretch where Rosaldo was clearly moving.
• Climbed from 20th to 19th among women by the second checkpoint and held that position all the way to the finish.

Jesus Rosaldo made the trip from Queretaro, Mexico to San Francisco and got the job done — crossing in 2:37:49 at a 12:02/mi pace to claim the NB45-49 field outright. With no one else in the category to push against, the race became a personal challenge against the course itself, and Rosaldo saw it through to the line.

The most telling moment came on the 6.62M→7.12M stretch, where Rosaldo posted the 15th-fastest split on that segment among the women in the field — a genuine burst of speed in the back half of the race that stood out against the broader women's field. That effort also corresponded with the one positional move of the day, climbing from 20th to 19th among women by mile 7 and locking that place in for the remainder of the race.

A solo effort, yes — but a completed one, over 13.1 miles of San Francisco's demanding streets, with a competitive split tucked inside it.
