Join us for a point-to-point tour of the Northern Kettle Moraine Ice Age Trail!
It's time to welcome Spring to the Northern Kettle Trail Running Community ... which means it will most likely be snowing!

At 7:00 AM, we will start at the Ridge Road Trailhead, just southwest of Sunburst Ski Hill. Transportation will be provided to the start from the finish (Greenbush Group Camp), leaving at 6:00 AM.

After we're done, we'll enjoy some food and refreshments at the Group Camp Shelter.

There will also be a 25k option that will start at Crooked Lake. Again, this run will be Point-to-Point, finishing at the Greenbush Group Camp.

The 25k will start from Crooked Lake. This stop is also where Aid will be provided to the 50k runners. See the map below for details.

Aid and access to drop bags for the 50k runners will also be provided at Mile 3.5 and at Mile 25. There is water available along the course at additional spots as well, at or near the backcountry shelters.
