Challenges are easier with friends!  We have a couple weeks to practice the idea of cold outdoor workouts.  Robin and I don't get much physical activity so she invited me to go walking with her in the mornings after she drops her kids off at school.  It was pretty cold out, we made it 25 min.  We have a couple weeks to work on lasting longer in the cold!  I don't think I would have a chance of meeting this challenge without having friends by my side!  Let's hope that by March my bladder adjusts to all the water I have been drinking, uptaking my fluid to a gallon a day!
