Notes
Virtual Birkie Fail.
I skied about 7 miles between breaks, and I took it easy on my breaks (plenty of water, gel, snacks). I could feel some minor onset of cramps during the 3rd leg. When I headed out for the 4th leg, I was extremely exhausted and crampy; I made it about 1.3 miles then quit. I had nothing left. Only went 22.6 miles, not even close.
