About the race
2025 HARRA Warm-up Series Bundles is a Houston, Texas-based fall training series designed for runners aiming to complete a full or half marathon in January. The program offers a progression of races and distances, including Space City 10 Miler, UTHealth Houston Half Marathon and 10K, Houston 25K & 10-Mile, and Coach Andy Stewart's 30K & 10K. The four races form a structured buildup toward the Chevron Houston Marathon and Aramco Half Marathon.
Bundles let participants sign up for all events at once at a discounted, fixed price, even though each race maintains its own signup pages. The series has a charity-minded history, with proceeds supporting local causes such as Memorial Park lighting. The series is not directly affiliated with the Chevron Houston Marathon.
