Weightloss plateau - do you do any resistance work? Medium-weight/high rep weight work (like the famous Bodypump we keep going on about ) is FANTASTIC for giving your metabolism a kick up the booty, AND it will help with the running because the stronger your muscles get, the more energy they can store, and the farther you can run (i ran for a year without bodypump and a year with and i am shaving MINUTES off my race times). Maybe you can pick up a class at a local gym?
