Best Races Near San Antonio

This page covers every race we list within 30 miles of downtown San Antonio, which takes in Boerne, Helotes and Bulverde along with the city itself. Most of them are 5Ks, and about half fall between October and December, when the heat finally breaks.

Only a few races here have enough public data for a composite score, so read this list for what's on rather than as a final verdict. Below the scored races, the ones whose age we know are ranked by how long they've been run. San Antonio's long-running themed 5Ks show up there: Día de los Muertos in October, Be My Valentine in February and the Lotería Run in April have each been held for well over a decade.

The biggest race of the year is the San Antonio Marathon, with a half and a 5K, on December 4, 2026. It's the city's own event, launched to replace Rock 'n' Roll San Antonio after a 16-year run, and its first edition, in December 2025, drew 3,335 marathon finishers.

Listings come from RunSignup, so a race that registers somewhere else won't appear unless it's added by hand. If a San Antonio race is missing, suggest it at bestraces.com/suggest. Scores use public data only and are never sold.
