Sometimes when you set a schedule, you have to accept it when things don’t go the way you expect. Instead of dropping off the face of the earth, you can accept that you had a reason for not running. Mine was my calves. Goodness gracious, my calves were sore and I don’t usually get sore calves from running. I think it had to do with the shoes I was wearing or with the fact that I ran nonstop for 20 minutes.
I usually end up doing a few walks during my runs so that way I can relax a bit and then start up again. The point in me running the full 20 minutes was to help me get used to running longer periods of time. It’s okay to take a few days off but get back on the horse as soon as you can and focus. Today I am doing two different work-outs so that way I can make up for missing my work out yesterday. One is to be TurboFire which is my cross training, the other is my wednesday run.

Way to go in only taking 2 days off! My knee was bothering me and I took a whole week off! Best thing to do is to get back at it and you’ve certainly done that with your TWO workouts!
