PB&J Fuel Run 5K/10K/13.1 SAN ANTONIO

PB&J Fuel Run 5K/10K/13.1 SAN ANTONIO is scheduled in San Antonio, Texas, on October 31, 2026. The half marathon (13.1 miles), the 10K, the 5K and a one-mile family fun run all start at 7:30 a.m. on the road.

For anyone at the beginning of their running life, the 5K is the format that does the most good. Eight weeks of three runs a week, most of them easy and some of them walked, is enough to get you across the line comfortably, and finishing one tends to make the next goal feel obvious. Runners already covering thirty miles a week will get more out of the half, where the challenge shifts from covering the distance to holding a pace once the legs start asking questions around mile nine.
