Dirty Dog Trail Marathon & Half

The Dirty Dog Trail Marathon and Half Marathon races will be held in the Boise foothills on the spectacular Ridge to Rivers Trail System. The marathon course is challenging with big climbs and fast descents filled with lots of great single track. The first man and woman to reach the top of the Hard Guy climb will find a $100 bill waiting for them! The half marathon course is challenging yet great for a first time trail race. There is a combination of single track trails and some dirt road sections. There will be plenty of well stocked aid stations with enthusiastic volunteers. Come enjoy the amazing trails in our backyard here in Boise!
