Registration begins on 2/1/2015 via a downloadable application from a pdf link on this page. There will be a limit of 150 runners. Preference will be given to those who have previously completed Manitou. You should also send a self-addressed stamped envelope with your application. After acceptance, you will receive an e-mail with a second USATF waiver and then detailed instructions.
The fee is $120 for the 50 mile, and $150 for a relay team (divided between 2 or 3 people). There is a 25% discount for first responders and military. This will cover your race entry, optional bus ride, t-shirt, all aid you get along the way, any other swag we can come up with, and your post-race meal for you and one pacer or crew. Additional meals probably available for purchase (will be a reasonable price).
