Welcome to the Second Annual Runfield Texas Race Series, a 5 race series to push your limits through the year and have some fun while doing so! Thanks to our safety plan developed in conjunction with the University of Texas School of Public Health, we were the first in-person race to be safely held in the state of Texas last year. So while other races might be getting postponed or cancelled, you can be sure that we will safely hold our events because we run better together! This year each race will have chip timing, race medals at each event, and official race photos. 

The series will begin May 1st with a 5K and progress throughout the year towards a half marathon - that's 13.1 miles! You can register for the Whole Enchilada (all five races) for a discounted price AND get a handmade Texas flag medal hanger to proudly display your hard work. 

We will have an in-person event on the race date, but participants can also run a virtual option of this if they so choose. If the participant "missed" the race, either for personal reasons or they signed up for the entire series after the in-person race date, the participant can run the prescribed racecourse and submit their times to be included in the results and be eligible for awards. For more information, please see the FAQ. 

This race and any proceeds are 100% in support of Outsiders Anonymous - an organization supporting people in recovery through fitness and a sober community. To find out more, please visit Thanks to a wonderful donor we are proud to offer free registration to anyone in recovery. For more information, please contact
