I've decided to run a marathon, probably next May. Haven't done much long distance running before, but for the last 3-4 weeks I've been doing regular runs. The aim is just to do it in under 4 hours. This week: Tuesday: 6.2km in 33 mins Friday: 8.2km in 42 mins Sunday: 10.4km in 63 mins (some hills on this run) Not that fast, but at the moment just trying to get the base mileage up. Anyone else done one?
