My first marathon was the London many years ago - pre ipods; sports gels etc etc
Finished in 4.12 and had trained for a year before hand by doing 3 HM's. Sitting watching the marathon the year before and decided I'd love to do it, so bought a ticket through the local travel agent (how things have changed!!).
really enjoyed it, never 'hit the wall' and am considering applying for the ballot this year......
