Last run before Long Mynd (unsupported run)

Ran my last run of 6m before Saturday's unsupported attempt of The Long Mynd. Not a great run, but felt really tired when I set off so I'm not surprised. Had to stop at a 24hr garage to get a mars bar as my legs were very shaky - not had that for a while! Will make sure I load up on good food tomorrow before the long drive down to Shropshire.
