I love the Virgin London Marathon Facebook page, there's always loads of inspiration on there :)
Over the past few weeks, to psych myself up and get in the zone, I re-read lots of running books and articles that I read during the marathon training last year. When you're tired and flagging and can't be arsed going out for yet another training run (!) it's great to be reminded that anything can be done if you're willing to commit, put in the hard yards and don't give up!
Have a happy Monday! :D
