The Thunder Dash, Comfort

The undulating landscape of Texas's hill country isn't just for gazing at or journaling atop—it's also for conquering. That's why The Thunder Dash descends upon the postcard-pretty and cardiovascular-challenging stretch of land for a hybridized fitness challenge. Participants meander on winding paths for a 5K obstacle course, where they'll sprint through natural mud pits and climb into 30-foot quarries. They can also tackle the 5K fitness challenge, which pairs racing with a series of calisthenics—such as burpees, jumping jacks, and Electric Slides—performed at stations every half mile.
