I have been commuting 2 or 3 days a week for a little more than a month now. Today was the first time I rode in two days in a row. Yesterdays ride home was really hard because of the strong headwinds so I thought I would be pretty tired today. This mornings ride was really good but all day I felt like my legs were a little tired. I thought the ride home would be tuff but I made it home in record time. My legs felt really good and I was flying (well at least for me). I came close to that 16mph avg I have been shooting for on my round trip. Maybe next week.
