Trying to make my recovery rides count

Sunday I averaged 9 mph for 13 miles and rode in to work to play catch up from being off of on Bike to Work Day. My right knee is acting up so I spun in very easy gears. I popped some Ibuprofen yesterday and today and have been taking Glucosomine for about a week in hopes it will help my rapidly aging body. This morning's ride into work the knee felt a little better. I am putting some Speedplay Frog pedals on as soon as they come in from the LBS. They are supposed to be knee friendly with 20 degrees of float.

I am going to try to make it to the Kernel's recovery ride tonight if I can make it off work in time. The owner is in so I can not plan anything but work for now.
