Back to Back days

When I decided to do this I wanted to have a couple of friends with me on this journey.  So, I asked my neighbor, Denise, who I've known now for over 6 years.  She is a few years younger than me and has run the Houston Marathon a couple of times.  Then I asked my boss - now she on the other hand is a whole lot younger than me and so much more in shape!  She also lives in the neighborhood.  This way no excuse - we just meet at the front and off we go.  David is our coach and has planned out the routes we take and makes me (at least) accountable.  So after our 10 mile ride yesterday we had this brilliant idea to leave our bikes at school and go on a ride after hours.  Great idea!  Uh....we did 6.7 miles with a head wind and my thighs were screaming!  We both decided that it will take us at least a "million years" to complete the MS150!  Can you tell I teach elementary students?
