Greenhorn Adventure Race

Welcome to Adventure Racing!  The Greenhorn AR, now in our 9th edition, was created to offer competitors a gateway into the sport of adventure racing. This 4 hour sprint adventure race was designed with the beginner in mind, but fun for everyone no matter the skill or experience level! While there is significant challenge built in, this event is fun and highly achievable for the novice racer. The navigation is straight forward and the maps that we provide are excellent. The mountain biking takes racers over gravel roads, some pavement, and semi-technical singletrack trails.  Finally, the paddling takes place on a clear lake.

See who is racing!
