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

PB&J Fuel Run 5K/10K/13.1 SAN DIEGO takes place in San Diego, California, on October 31, 2026, with the half marathon (13.1 miles), the 10K, the 5K and a one-mile family fun run all starting at 7:30 a.m. It is a relaxed, come-as-you-are event where runners and walkers of every level are welcome, timing is optional and handled through your own running app, and every entrant receives a swag bag with a race shirt and a finisher medal. Both in-person and virtual participation are offered.

Self-timing turns the morning into your own time trial, which is more useful than it sounds: you set the target, you hold the pace, and there is nobody around you to drag you out too fast. Pick a distance that matches your training, start conservatively, and use the result as the baseline for your winter block.
