Common Goals:

The event is intended to be low key, inexpensive, and a good excuse for a Saturday morning gathering of friends... or friends-to-be! The course consists of gravel roads on and around Jump off Joe Mountain near Kennewick, WA and will provide participants with great views, once you get up the challenging hills that is. The race more closely resembles a trail run than a road race as the aid stations are spaced between 3 and 5 miles apart and offer real food choices like PB&Js, chips, cookies, and fruit. Please come prepared with means of carrying water as you may be travelling up to an hour between aid stations and it can get hot out there. Source
