Before I ran the London Marathon on Sunday I was told that I would ‘enjoy the first 15 miles’ and ‘be buoyed by the crowd’. No such luck. It hurt from the start – I never hit the famous ‘wall’, just felt a steady increase of pain over time – and the crowd might as well not have been there, as far as I was concerned. I posted 3 hours and 37 minutes, which if I have some kind of memory lapse, I will probably try to better in the future. It would be ungrateful of me, however, not to recognise that it’s been a bit of a struggle in the last century for women to be allowed to compete in marathons at all. Women have fought for my right to feel that amount of discomfort. For many years it was felt that women’s bodies could not withstand the stress of 26.3 miles.
