THE RACE

The Cross Timbers Marathon Series

The Cross Timbers Marathon is a USATF-certified event set among the scenic countryside and rolling terrain of North Texas. As a signature race series, it offers multiple distances — Marathon, Half Marathon, and 10K — designed to welcome runners of every experience level, from first-timers taking on their debut race to seasoned competitors chasing personal records. The event is built around a warm community atmosphere, attentive course support, and a distinctly local character that sets it apart from larger metropolitan races.

USATF certification means that the course has been precisely and independently measured to official standards, making your finish time eligible for use as a qualifying result — including Boston Qualifier consideration for the marathon distance. As a USATF-sanctioned event, all race operations are conducted under official road racing guidelines, ensuring fair competition and a credible, recognized result for every participant.
