We added one new race to the Ultra Cup series this year, Run Rabbit Run 50 in Steamboat, Colorado on September 18, 2010. This race has been full for a little while now. However, registration will reopen tomorrow, August 11th at 9am Mountain Time for 25 entries, and all remaining entries are contingent upon registering for the Montrail Ultra Cup. Register for the Ultra Cup series first, then register for Run Rabbit Run 50.
A major thanks goes out to the Forest Service near Steamboat Springs, CO and the Run Rabbit Run 50 crew for stepping up to increase the field size for the race this year.
