Carpenter St. Croix Valley Nature Center near Afton is celebrating spring on May 19 with its annual Apple Blossom Races.
There are three races — a 5K, a 10K and a half-marathon — and they all begin at 8 a.m. at St. Croix Bluffs Regional Park north of the center at 10191 St. Croix Trail S. in Hastings.
All races finish in front of the Nature Center's interpretive center.
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.
A 2K Fun Run will start at the Nature Center at 11:15 a.m., or as soon as the last half-marathon runner finishes.
The hilly half-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.
More information and online registration is available at http://carpenternaturecenter.org/events/apple-blossom-race/. The registration area will be located in Carpenter Nature Center's parking lot. All parking is at the Nature Center.
