NK50k - Greenbush, WI

NK50k is a trail event on the Northern Kettle Moraine Ice Age Trail near Greenbush, WI. The event offers multiple distances:

  • 50K
  • 25K

The 50K is a point to point course that runs along the Ice Age Trail, with the finish at Greenbush Group Camp and the start at Ridge Road Trailhead near Sunburst Ski Hill. Transportation from Greenbush Group Camp to the start is provided. Aid and drop bag access for 50K runners are scheduled at Mile 3.5 and Mile 25, and additional water is available at or near backcountry shelters along the course. Aid station supplies include water, sports drink, Coke, Mt. Dew and assorted typical ultra aid station foods. After the run, food and refreshments are available at the Group Camp Shelter.

The organizer describes the event as a fun run rather than a race; no results will be posted on UltraSignup.com. The event notes limited availability and that it may sell out. A finisher sticker is offered and the listing indicates a registration fee of USD 24.58 with two offers shown. Registration closes on Thu, Apr 1 at 11:59 PM CT. Participants should expect to be largely self-reliant as aid locations and availability can change. Visit the organization's website for the most recent information.
