2018 Tough Mudder Half Seattle’s got everything a wiley unicorn like you could ever ask for.

A 100-year old coal heap you have to scale if you want to reach the finish. And a feature so unique, it only exists at Tough Mudder Half Seattle - black coal mud. Put it all together and what do you get? The Coolest Event on the Planet (And Maybe the Universe) in the 2018 Season.

5 miles, 13 obstacles

So what’re you waiting for, Mudder. Gather up a gaggle of unstoppable unicorns and high-step your way to Tough Mudder Half Seattle in 2018 for your best weekend of the season.
