I read meters all day so I walk usually 5-6 hours a day at a pretty fast pace with little or no breaks so there are days when I am beat and the last thing I want to do is get on a bike for 2 hours after work. Most of the time it isn't a big deal but there are some days where I just take the day off and take a hour long nap when I get home. I think if I had a different job I would get better results in my races but I love working outside in the elements and with dogs....
