I believe only those atheletes/sportspeople who have a focused event, and have shown the determination to achieve such a goal can really appreciate the hard work involved. I ran the London Marathon last year, and I know just how how it was to be focused on the mornings of long runs, and when the weather was particularly bad during the winter. Overall, I never can back from training wishing I hadn't bothered. I've now done the marthon twice, I can tell you it is a brilliantly organised event, and the support the crowd give you is something that is hard to put into words. I've done many challenging things, but completing the marathon (in whatever time) was the most satisfying thing ever........what ever anyone says, this is an event not to be missed, perhaps not for personal bests, but for the shear guts and determination you will see from fellow runners........stick with it......good luck
