The 8 Hour Adventure Race dubbed the Smith Rock Spring Sting is getting a lot of attention from the race watchers.
It got listed in Men's Journal as One of the 52 Best Races to Enter in 2015. The organizers call this the "perfect race for beginners as well as more experienced racers who are looking for a shorter race."
Scramble the trails and ford the Crooked River at Smith Rock State Park. With basic navigation skills, you get to run, trek, mountain bike, paddle and practice those orienteering skills.
