I did a 40 mile ride over the weekend with my snow bike and trailer. Everything was kosher until about five miles from home when a cold NE wind hit me and I felt my sails deflate. I was dragging all the way home. So badly that I had to stop and check my tire pressure to make sure it wasn't a flat. But the "flat" was me Routes that I ordinarily eat up and spit out were killing me.
Is there a trick to beating this "wall" of exhaustion? I tried stopping and resting a bit, but that only made me start to stiffen up and get cold. It was subfreezing after a day in the 30's and my sweaty clothes were like ice. Is it just a matter of more traning?
I also tried drinking some more and eating a power bar but both water and bar stuck in my gut like a brick. My digestion shut down.
I suspect part of it may have been hidden dehydration that was covered up to some extent by the cold air. When it's cold I have to remind myself to drink.
Ideas and suggestions would be welcome, though.
