On February 6, 2027, history will be made in the Dallas–Fort Worth area with the launch of the Lake Ray Roberts 100K, featuring the first-ever out-and-back 100K in the DFW area.
This isn’t just another ultra. It’s a new kind of challenge for ultrarunners. Runners will take on 100 kilometers of Texas terrain in an unforgettable out-and-back course, pushing deep into the distance before turning around and retracing every hard-earned mile back to the finish.
The out-and-back format creates a unique test of endurance, determination, and mental toughness. Every mile takes you farther from the finish, and every mile on the way back brings you one step closer. With full race support, strategically placed aid stations, and the relentless spirit of Texas grit, this event is built to push runners beyond what they thought possible.
