Without an impossible challenge to rise to, man would have never have walked on the moon, decoded the human genome, or alphabetized the color wheel. Test your inner Ajax with today's Groupon: for $84, you get entrance for one to Tough Mudder's SoCal event at Snow Valley Mountain Resort in Running Springs on either Saturday, May 28 or Sunday, May 29 (a $160.75 value). This Groupon includes registration and insurance fees.

The challenging 10-mile Tough Mudder obstacle course was designed by British Special Forces to test all-around strength, endurance, mental determination, and camaraderie, with all sponsorship proceeds benefitting the Wounded Warriors Project. Over the course of an estimated 2.5 hours, rugged participants weave their way through a diverse terrain that boasts 21 demanding obstacles, including muddy trenches, water obstacles, high walls, slippery slopes, live wires, and a gauntlet of fire. Tough Mudder challenges the fittest of fit athletes, demanding mental toughness to match physical prowess, but emphasizes the course as a personal challenge, and not a race. Times are not kept, and it's about conquering the course rather than besting fellow Mudderers. Hardened course finishers enjoy a post-contest party with live music and a 48-hour glow of invincibility.

• Mudder's inaugural US challenge is the brainchild of two Brit buds who designed the layout based on their own terrifying real-life experiences: hunting down terrorists in the Middle East, and...being a lawyer! – Thrillist
• Their Tri-State event was full of serious obstacles, challenging terrain, and on-course camaraderie you won’t find anywhere else. – TRAVLETE
