The 2013 Enchanted Rock Extreme Duathlon was held on Sunday near Fredericksburg.
About 175 racers participated in the race, which required a five-mile run, a 16-mile bike ride and a 1.2-mile climb up Enchanted Rock. The race's motto was "No whining."
KVUE's Ed Sparks took photos of the event. Click here to view the slideshow.
