Concerns About Pilgrimage

In an attempt to build up endurance, I biked about 18 miles yesterday. I overdid it and my back is horribly sore and everything is foggy in my mind. I have degenerative disc disease, but have been taking very good care of myself and haven't suffered much pain in recent years. I am re-thinking the necessity to walk to Los Angeles and am considering alternatives such as: walking along every beach in San Diego, handing out postcards until I run out, with Alex filming this. I think pain always makes re-thinking a priority. I will continue the endurance training, however, with more foresight regarding the amount of exercise I do. Still no word from anyone regarding my request for time off.
