    • Everyone knows it can be tough at the top, but this tough?

      Should tough guys — or even Tough Mudders — blub? And if so, should they share it with the world? It turns out that the answer is “yes”. Will Dean, for example, has embraced his new-mandom, despite building up the world’s largest obstacle course company and running very fast in an attempt to get back to a slower lane.

    • Good Morning Britain's Susanna Reid and Kate Garraway Get Down & Dirty in Pitiless Tough Mudder Challenge

      They're usually seen preened to perfection for their stint on daytime television. But it was a different story on Wednesday afternoon as Good Morning Britain's Susanna Reid and Kate Garraway swapped their on-set sofa for mud-infested park as they took part in the relentless Tough Mudder challenge.

Event Photos

Our photographers will be out there on the course taking action shots of you and your teammates. In the week after the event, stay tuned for an email with your photos and go to our Facebook page to view the event photo album. In the meantime, go check out our galleries on Mudder Nation.

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.
