​​The Backyard Ultra with the views.
Come run beautiful Lake Estes while supporting Childcare and Family Services in Estes Park.

The Backyard Ultra is a form of Ultra 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.....

All participants will receive a custom Fractel hat, stocked aid station, up to 10x10 space in the athlete village and a special DNF or finishers award.


4.252 miles 150' gain per yard
