13,600? Yes in one day, I have managed to make 30,500 steps in one day but I think that is my limit, my feet were really sore that time, I think I can keep a daily routine of fifteen k a day easily if I wanted to. It appears to me you must have misunderstood the number I wrote, I do it in letters to be able to comply with the 100 character rule for Actifit posts.
