Until mankind first stepped outside in 1934, nature was thought to be a fanciful myth, like yogurt or the clutch hitter. Spend a few hours frolicking through the fresh air of truth with today's Groupon: for $30, you get entry to Warrior Dash Central Texas on Sunday, November 21 (a $60 value). The muddy mini-marathon is held in Cedar Creek, about an hour and a half from San Antonio.

The Warrior Dash is bringing its wild course to Central Texas this November, offering extreme athletes a chance to partake in a thrilling footrace across 3.2 miles of diverse terrain. Along the way, runners are met with 11 challenging obstacles, including a giant pile of hay bales, a jungle of sticky wolf spider webs, and hellfire. Though the Warrior Dash provides challenges to even the fittest of fit athletes, mental toughness is the greatest tool for success, and people of all physical abilities can have fun and do well as long as they bring a good attitude and their best guts. All participants should arrive at least one hour before their scheduled departure time with a photo ID, a change of clothes (whatever you wear during the race will get filthy), and a signed copy of the participant waiver.

In addition to the race itself, participants receive a number of extras, including a Warrior Dash T-shirt, a fuzzy warrior helmet and medal to don every day after the race, free water, post-race granola bars and bananas, and one beer ticket (for racers 21+) to cash in upon completion. Make sure to bring extra cash if you'd like to purchase additional beer or food, as outside sustenance is not allowed. Throughout the day, participants can catch the Cowboys game on the Jumbotron, and live music guides participants through the melee. Soon after the race, participant times and photos of the event will be posted on Warrior Dash's website. Peruse the FAQ page to learn more.

• Yes, it was fun. It was hard at times, but mostly fun. Runners from all over the area had different reasons to try the Warrior Dash from " I got talked into it, " to " I needed a break from the usual races out there," my favorite, " I lost a bet in a drinking game." Whatever the reason, most said they would do it again. – David Wallach, Chicago Now
• All-in-all, it was a great event…and one we will never forget! – Team Hargrave, The Running Couple
