Running for Winter
Winter running exposes you to cold weather but if you keep your calves warm your flexibility keeps to a maximum and injuries to a minimum. If your calves are cold it causes your ankles to tighten and so your agility reduces increasing your chances of injury. In fact your whole body tightens (including your anti gravity system) if your calves are cold so make sure you wear long trousers or at least leg warmers that you can roll them down when your hot (if you get hot enough!).
