The Dirty Dog is back for 2021! We are so excited to see everyone again. Things have improved rapidly and the mask mandate has been lifted so it looks like we will be able to run mask-free and we can have our finish line taco truck party!
Please feel free to wear a mask if you want to though, we want everyone to feel safe and comfortable.
The Dirty Dog Trail Marathon and Half Marathon races return for the 5th year 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!
Aid Stations for the Half Marathon are at miles 4.5, 6.8 and 8.9 and Aid Stations for the Full Marathon are at miles 4.5, 6.8, 14.5 and 21.5
If you register after Tuesday, June 15th, you will not be guaranteed a shirt, as the order for the tanks need to be made by this date.
