Afterwards I jogged for about a half mile up hill and it was the most glorious feeling I've ever felt. I could feel muscles in my legs that I haven't used in months start to warm up. It was almost like layers peeling off as I ran. It's hard to describe but it was an awesome feeling.
Sometimes I really do find it quite strange to be a 22 year old with atrial fibrillations (fast &irregular heart rate) but that's okay. I think I was just born with the heart of an 80 year old man. ;)
