Combination of HEAVY wet snow and a grade that got steeper as I went higher. As you can see, the sled just started slowing down towards the top and I turned out before I got stuck.
Wonder what a few more pounds of boost would have done for track speed.
Later that same day I went up a much steeper climb and just BURIED her 4ft into the snow when I wasn't able to turn out before the tunnel dug in hard.
