I'm wondering whether this happens to anyone else. It seems so weird to feel so cold from biking, even hours later!
Yes, this sometimes happens to me too! I've figured out that the cause is metabolic. I've either not eaten enough, or my body has prioritized digestion over staying warm. It has been mentioned that digestion can stop during hard exercise. Presumably it restarts post exercise.
