I just got back from a 5 mile run. If you asked me six months ago if I would be able to run for 5 miles without stopping, I would have thought you were nuts. I couldn't even run for a mile without stopping--I never have been able to. In high school, I was always "that" guy that would run for about 200m on the track and walk the rest of the mile. I could actually keep up with everyone for that 200m, and even sometimes be in the lead. I think I have started a conversion from fast twitch, sprinting muscles, to slow twitch, endurance muscles.
To me it's odd to feel good after a run.
Up next in my training, short 1000yd "recovery" swim today and a 45 mile bike ride tomorrow.
