We’ve electrocuted you, frozen you, thrown you through fire and even tried to tear gas you. Now it’s your turn to dream up the next twisted obstacle for you and your fellow Mudders to take on in 2018. We want YOU to unleash your inner mad scientist to design the next fear-inducing, pulse-racing test of mental grit. Take part in our 2nd Annual Extreme Obstacle Design Challenge. We dare you.

Submit and share your design for a chance to win a trip for two to Las Vegas to our top secret obstacle testing event where we will build your obstacle - and you can test it out for yourself. Maybe you’ll even see it on course in 2018...

Submit your sadistic sketches now through June 21st.
The top 10 finalists will be chosen to battle it out for the Grand Prize.
May the maddest Mudder win.
