Event Info

The Course starts and finishes at Fort Boise Park in Boise Idaho.  The race is run completely on dirt roads.  This course is an out and back, meaning you climb to 3.1 miles and then turn around and descend back to the Start/ Finish Line.  The course is challenging but is a great trial run for training for trail running.  The race utilizes the Military Reserve Area behind Fort Boise Park.  Runners will “follow the Rules of the Road” meaning the dirt road will not be closed to the public.

Community Partnership

The charity of choice for the Les Bois 10K is The ARC. The Arc was founded in 1956 by a small group of parents and other concerned individuals. At that time, little was known about the condition of people with developmental and intellectual disabilities or its causes, and there were virtually no programs and activities in communities to assist in the development and care of children and adults with developmental and intellectual disabilities and to help support families.

As its primary funding source, The Arc operates a Donation Call Center and pick up service that solicits clothing and household goods to fulfill contracts with the Savers thrift stores.
During its 50+ years, The Arc has grown to offer a comprehensive array of services and supports. Over 600 people with intellectual or developmental disabilities in Southwest Idaho receive services through our vocationalresidential, recreational, and developmental programs.
