So, I was nice and warm riding today. No problem.
But when I came in, I was suddenly cold and could not warm up! I ended up being in sweats and a robe under 2 down blankets and a quilt in front of a fireplace and slept all day until 4:30. Now I'm up and about, not cold, except for my hands and feet. It's not just a sensation...they are literally ice cold.
Did I get cold and not know it? That seems like a bad deal. When doing other winter sports, I've always been able to judge my temperature, so maybe there's something different about biking?
