About the 2026 HARRA Warm-Up Series
The HARRA Warm-Up Series is a progression of races spaced across the fall, each one longer than the last, designed to carry marathon and half marathon hopefuls into race shape by winter. The distances build gradually, so your long training weekends have a bib attached. Each race is run by a separate local organization, and a portion of proceeds from the series has historically gone to area charities.
Signing up through the HARRA bundle covers all the races at once at a bundled price, rather than registering for each event separately. The races are organized by different groups, so details like parking and packet pickup will vary by event. Houston Area Road Runners Association handles the bundle registration itself.
