I am on a 19 day walking streak. I either walk outside or on the treadmill. I try for 2 miles but sometimes that always doesnt work. The girls love it when I walk on the treadmill becasue they always want to take a turn. Courtney walked for 25 minutes one day. Samantha decided she could run 8 mph and ended up falling and getting a treadmill burn on her arm. Ouch I dont think she will go that fast again!
