Cross train bike

I was very stiff and sore this morning from yesterday's long run.  I planned to ride my bike today because I knew I would need a day or two off because of how hard the run was.  So I took my mountain bike on the paved trails for a nice and easy ride.  My only goals were to get my heart rate up, get my legs pumping and loosened up and do it for at least 30 minutes.  Mission accomplished.
