PB&J Fuel Run 5K/10K/13.1 MIAMI

PB&J Fuel Run 5K/10K/13.1 MIAMI takes place in Key Biscayne, Florida, on October 31, 2026, with a half marathon (13.1 miles), a 10K, a 5K and a one-mile family fun run all starting at 7:30 a.m. The event is deliberately low-key and open to every pace and age: timing is optional, either through an app or with help from the organizers, entries are capped to keep the atmosphere manageable, and each participant receives a swag bag with a race shirt and a finisher medal mailed out to them. A virtual option is also available.

A small field and no timing pressure make this a sensible place to try 13.1 for the first time. Build toward a long run of about eleven miles, walk through the aid you need, and treat finishing as the whole objective. The clock can wait for the next one.
