You're not kidding! I've never experienced an endorphin high before and it was really lovely! I tend to have a dark cloud hovering over my head at all times, and it was like someone blew that thing away and hung rainbows up in my sky. Very cool! I am not sure why I haven't experienced this with summer cycling, but I very much want to figure out how to reproduce it regularly.
