Training for my first Marathon - London 2010 by Clare350

I have been running for about 5 years now, I'm not a natural runner, but always try my best!  I have managed to gain a place in the London Marathon 2010 and have recently started training.  I have never run further than 13 miles and could do with some guidance between now and April 25th on routine and nutrition too.  Hopefully my blog will generate some helpful comments from 'professionals' in order to get me there fit and well and able to do my best on the day!  I'm 39, busy with a full time job ... but thats not excuse, we are all busy people these days!!
