RASTA has established a 13.5k race course for the Boulder Mountain Tour (BMT) that explores the varied terrain of the Washburn Lake Silent Sports cross country ski trails. All racers will start from the Perch Lake Shelter and follow a well marked race course that leads skiers out into a undulating course that we are sure all skiers will enjoy. Upon finishing a lap, the racer then completes additional laps to complete their 15k or 30k race. GPS tracks of the course can be downloaded at http://rastatrails.org/events/
The Rhinelander Area Silent Trails Association (RASTA) maintains the Oneida County, Washburn Lake Silent Sports Trails Area cross country ski trails which are located adjacent to Perch Lake Park. The trailhead has a warming shelter that provides access to 20 miles of cross country ski trails that are groomed for both classic and freestyle techniques.
