Started a 30 day run challenge today. Nothing too special but something to get me started and ready for spring. Nice winter night to get in a run so I couldn’t have picked a better night to get started. I finished up work at about 8:00. I ate some dinner and then headed out about nine. Felt pretty good then about halfway my knee started acting up. It only bugs me when I am out of shape so that is a good indication of my condition...
