Apple Blossom Races


May 15, 2016

Celebrate Spring with Carpenter St. Croix Valley Nature Center’s Apple Blossom Races. The 5K uses all paved surfaces, walkers are welcome on the 5K only.  The 10K uses some of the same route but breaks off and follows almost 4 miles of the Nature Center’s trail system overlooking the St. Croix River. Some of the trails are not paved. The hilly 1/2 Marathon follows some local roadways near the Nature Center and passes many of the area’s apple orchards that promise to be at or near full bloom.
