I am working on getting in shape for our local MS 150. I did 43 miles this morning with one of my buddies. Took 2hrs 28 minutes. Still gotta work on getting in better shape, but I can definitely tell the difference that 3 weeks on the bike has made. Not really sore, and just called another buddy and will be doing another 30 tomorrow morning. I am trying to lose weight and I have to keep biking.
