Why do some events only have the 5K and 10K distances?

A big reason we created the new 10K distance for 2022 was to allow us to create the best courses possible at new and existing Tough Mudder venues.  For many events, we've had to really pack in some zigs and zags to get to 10 miles, leaving you running in circles and switchbacks. 

Our design team has worked to select the distances that work best for the venues we're in and ensure we can deliver amazing on-course experiences in every 2022 venue.
