Hi everyone, this Saturday night, with a few friends, I completed the 'Shine' Night Walk Half Marathon in London. Took us 5hrs 42minutes but I'm carrying a little more weight than I want and I'd twisted my ankle a fortnight ago. We also did very little training in the run-up to it. This is my third year in a row, I did around the same time last year and the year prior to that (when I weighed 4 stone less and had trained a bit better) we achieved 5hrs 16minutes. I really now want to try and do the Full Marathon for the same event next year, and my finger has been hovering over the 'book now' button all day. My worry, though, is am I up to it? I know some proper training is required and am willing to do it. I am also on the path to losing that weight I have gained over the last two years. Has anyone done similar, transitioning from a 13 mile walk to the 26 miler? If so, I would really appreciate some honest accounts, feedback and advice. Thank you.
