I had a chance to follow some sled dogs on a training run. I was on a snow sled to help stop the team as the snow was to fluffy to hold a snow hook. We went 38 miles at a 10.5 mph pace, it impressed the h=== out of me. That included stops for tangles and a longer stop for snacks supplements. Friend said next runs will be 3 days in a row at 50,60,50 miles before tapering for January race. Side note snow is crotch deep north of Two Harbors.
