Tucson

Tucson's running calendar is anchored by the Tucson Marathon, a net-downhill, Boston-qualifying course that's been run since 1969 — 17.3% of finishers qualified for Boston in 2025. The rest of the calendar is filled out by the TMC race series (10K, half marathon, and 8-mile events through Saguaro National Park) alongside community staples like the Pecan Classic and Breeze in the Trees. Here are the upcoming races in Tucson, updated weekly.
