Unholy Grail 2022

We get it: travel is tricky this year. That doesn't mean that you endurance crazies are off the hook though.  If you can't make it to World's Toughest Mudder to complete the Holy Grail, you can still earn the Unholy Grail over the course of a single (albeit very, very long) weekend. Here's what you need to know.

What is Unholy Grail?

The Unholy Grail is an incredible feat of endurance, so buckle up. To successfully complete the challenge, participants will need to complete the following over the course of the same event weekend:

• Tough Mudder Infinity - Complete a minimum of 20km on Saturday
• Toughest Mudder - Complete a minimum of 40km
• Tough Mudder 5k - Complete the 5km Course on Sunday after 8:00am
• Tough Mudder 10k - Complete the 10km Course on Sunday after 8:00am

For those keeping track at home, there are two opportunities to meet these criteria in 2022: Tough Mudder North West (Sep. 10-11) in the UK and Tough Mudder Philly (May 21-22) in the US.

Can I use my Season Pass+ to register for the Unholy Grail?

Absolutely! The Season Pass+ includes access to all of our events, including the 4 formats required for the Unholy Grail. Register for each of them individually and we'll know that you're in the hunt for the Grail.

What will I receive for finishing Unholy Grail?

There will be a custom Unholy Grail medal. These will be awarded post event once we can confirm each element has been completed.

Do I need to let you know that I have signed up for all 4 events to be able to receive my swag?

No, once you have signed up for all events we will see you in our system so you don’t need to worry about letting us know.
