Can I change from one day to the other?

All participants can request a transfer of their registration to another day at the same event! Transfers must be requested at the very latest by 11:30pm local time the week before your event weekend. 
Participants may change Event days by emailing the Tough Mudder Customer service team at and requesting a change of days. In your email, please include your full name and event you are registered for, as the day change and new wave time preference.
