Just got home. Ran home from Chester. My legs feel really tied. I must be on the edge of an injury. I decide not to do intervals this pm and instead to run a Tempo run (30 mins at about 5:50 pace). This is because I am reading Daniels' Running Formula at the moment and it recommends these types of runs so close to a marathon. If you are looking for a good running book then I can highly recommend it.
