Gorgeous day here in Chicago and was so excited to get outside and do my run (jog, very, very slow jog). I knew it was going to be challenging, but I had no idea how much. I barely made it through and honestly can't imagine being able to do W5R2 in 2 days. That just seem insurmountable. I do not want to fail, but what was I thinking when I decided at 62 that this was something to start. Any tips??
