This is was my 2nd Tuscobia Ultra Run. I’m in Rice Lake, WI It’s a 80-mile foot race on frozen snow-covered tundra, held on the Tuscobia State Trail in Northern Wisconsin. I do this event a month prior to running Arrowhead 135. It gets me acclimated to the cold, I learn a lot as to what I need to do and is a health and fitness barometor!
