Texas is home to more than just cattle, oil, the Cowboys football team and the Alamo. The Lone Star state also hosts a ton of triathlons. The Tri Raider Sprint, which is held at Buffalo Springs Lake, is one of the classics. Athletes begin in a spring-fed lake, head out for a 17.6-mile out-and-back bike that contains three climbs and finish with a 3.1-mile run on flat, somewhat shaded roads.
