Starting and ending on the historic State Fair of Texas fairgrounds, the Big D Texas Marathon proves that everything is bigger (and better) in Texas. Runners will pass Dallas notables, including State Fair Circle, White Rock Lake and the Santa Fe Trail. With only one true hill on the course and average temperatures in the 60s, this race provides a perfect opportunity to qualify for the Boston Marathon and achieve a new 26.2 PR at the same time. In true Texas fashion, celebrate your achievement with a "Big D" post-race party, complete with plenty of food, libations and Texas-sized activities.
