As each Endurance Challenge race reaches maximum capacity, runners will have the option to sign up for the event wait list. If a registered participant cancels, race entry will be granted to wait listed runners in the order their registration was received. The wait-listed runner will be contacted when race entry is granted. Upon acceptance into the event, entrants must confirm their intent to participate and submit their registration payment within 24 hours to secure their spot.

*The Marathon Relay registration fee is PER TEAM. The Team Captain must pay the fee in full. Although we recommend four participants per team, you may register two or three participants per team if you so choose.


All registered participants receive nutrition and hydration support at the Start/Finish Area. In addition, each distance receives the following:

 5K  X  X    X
 10K  X  X    X
 50K  X  X  X  X
 50 MILE  X  X  X  X


All race participant purchases are final. If, for any reason, you cannot participate, the entry fee will not be refunded; however, race gear will be available for pickup at anytime during regularly scheduled Packet Pickup hours and location(s) and on race day.

The North Face Endurance Challenge will take place rain or shine. Only a "force majeure" will be cause for cancellation. In the event of a cancellation, no refunds or credits will be applied to future events. Cancellation race gear will NOT be mailed.


If you wish to transfer your entry to another race distance or location, click the link on the registration page to change your distance or event. Have your confirmation or account number ready and follow the instructions. All transfers will incur a $10 Transfer Fee along with any incremental registration fees. Participants may not defer their registration to the following year.

All transfer requests must be received no later than the day of the race for which you are registered. No transfers will be accepted post race.
