Upcoming Races in San Marcos

The San Marcos race calendar is busiest in January, February, and March. It covers a range of endurance sports — you'll find races in Running and Trail Running — so there's usually a race near you. Distances span a wide range across those sports; you'll see 5K, 1 Mile, 10K, Half Marathon, and Marathon.

Weather on race day varies by time of year, so it lives where it’s accurate — each race page shows that race’s typical high, low, and rain chance from NOAA climate normals for its venue and date.
