Our race takes place in beautiful Estes Park Colorado at the YMCA of the Rockies. 
The Backyard Ultra is a form of Ultra Trail race where runners must complete 4.167 miles in less than one hour, every hour, until only one runner remains to complete a lap.
This runner is crowned the winner and only finisher, while all others will be marked as DNF. There is no predetermined end length or time - we go until only one remains.....

Rocky's Backyard is hosted at the YMCA of the Rockies campus which offers family fun and adventure. Kids of all ages will have plenty to do while your athlete competes for a yet unknown number of hours. We recommend staying on campus at the YMCA or at any Estes Park lodging establishment. Our preferred lodging partner aside from the YMCA is the Estes Park Quality Inn - friend's of the race, locally owned and operated
