In my long running career marathons were never an appeal (although manage to run London twice in the 90's) but the half marathon has always had a magical distance. I feel that if I can just reach the ten miles I will complete. In my younger running days my goal was a sub 1.30 and I did achieve with the help of my trusty casio as I needed to be running at 6.50 mile pace to get under the magical 1hr 30 (no fancy garmin then!) So it's a thinking runners distance working out best strategy as the miles gradually disappear. I prefer half marathons that are a bit more challenging and my personal favourite is prob now the Fromehalf run on a hilly traffic free course in July....do you have a favourite?
