One of the West Coast’s most vicious courses, our main mission in Seattle is to turn the Emerald City filthy Mudder-brown.

Tough Mudder Tattoos

Many Mudders like to get a tattoo of our logo to commemorate their achievement. We think this is great, so once you get inked, fill out a tattoo registration entry form to get free entry into a Tough Mudder event of your choice. Please note: our UK, AU and CAN venues don't allow tattoos on-site, so you'll need to find a local establishment that can oblige.
