Signing up for a gym or joining a running club is great for staying in shape, but when it’s time to take body to the brink, a few extra curls just won’t do. Whether it's racing up a skyscraper, paddling the Pacific, or stepping into the ring, these are the best 12 ways to push yourself harder.
Try a Mudder
Distance: 3 to 4 miles
Intensity: Mild. "You're going to get muddy, you're going to get wet – but you're going to have fun," says Brett Stewart, creator of the mudrunguide.com, a resource for OCR fans.
Obstacles: 12, including wading through deep mud, climbing rope ladders, and leaping through fire. [warriordash.com]

Intensity: Mild. "Slightly more difficult than a Warrior Dash," Stewart says, "and definitely a lot muddier and dirtier. They're not afraid to put obstacles in water just to make them harder."
Obstacles: 25, including underground tunnels, a 50-foot waterslide, jumping through fire, and climbing towers of shipping containers. [ruggedmaniac.com/locations]
