March 100 mile challenge

Hi, I'm new to the community boards, but i have been using MyFitnessPal for a while. I am starting a 100 mile challenge for March to add to my weight loss and health efforts. I run a little and do mostly power walking. My goal is to just get 100 miles in the books and challenge myself to maintain a regular exercise regiment. My miles will include running, walking, and walking my dog. I would love for other to join me in logging our miles on this journey.
