I chose to do an exercise that has been around since the beginning of time, but just not around much if my life. I jogged outside. Certainly not a difficult concept but difficult for me to get the courage to do it. This challenge gave me the courage. Twice I jogged in the morning just before daylight. Twice I jogged just after dark. If you can't tell, it's really not something I feel comfortable for the folks outside to see. It was nice. Not great, not mind blowing-it was just as the challenge requested: different.
