I desire so much out of life, mostly activities that I can do.  Stand-up paddleboarding, kayaking, just one triathlon, using a non-stationary bike, and running.  Running so much, oh I do miss it.  When I stopped running, my weight shot up to higher than it had ever been before, so much so that I couldn't run anymore.  That's what my doc told me.  She said I had patella-femoral syndrome.  She sent me to physical therapy, where the workouts I wanted to do to lose weight were restricted, and I was so frustrated with the seemingly menial movements I had to perform daily to get my knees back in shape.  I was allowed to swim, so swim I did. 

After six months of physical therapy, I graduated to riding a stationary bike, and I am just now moving on to an elliptical (a far cry from running on an open road but still a great workout). 

By the time I graduate to running, there will still be run shoes in stores and paddleboards and kayaks to find.  The key for me is patience and perserverance.  One day at a time.  One month at a time.
