How does a fuel belt work? I am drawn to this belt but I am not sure what to put in the cute bottles. I could have used this for water many times in the past but I am not sure about the idea of carrying it. Does it chafe? Does it bounce? Would it freeze in the winter? Also, I think most of my future running in the heat will include a jogging stroller that holds water just fine. I am contemplating asking for this for Christmas. That way its something I want but maybe not something I need to spend my own money on. That way if it bonks I will not have to think about the fourty dollars I have wasted. I did buy some yaktrax because living in Michigan that seems like a totally needed purchase if I plan to use the outdoors as my personal gym.
