Was a nice day for a ride, low wind 40 degrees the only thing missing were my legs. My legs didn't feel real bad until I got out on the road then I knew I might be in trouble. From last night's ride my legs were a lot more drained then I thought. To make matters worse my bad started to hurt really bad. My HR was very high even though I didn't feel as if I was pushing that hard. I know when my back hurts my HR goes up and when my legs are toast it also goes up. I cut my part of the ride short because my back was in so much pain and lower quads were cramping. It was nice to ride outside though. Thanks to Sid for doing all the pulling, I wanted to do my share but I was working way to hard from the back, I could only imagine what I would have happened to me trying to pull and maintain the pace...
