Work Run

This afternoon i went for a 4 miler in the hills not far from a Quarry i was working at today. Does running in the hills make you a better a runner on the flat? Anyway it certainly makes me work a lot harder. This weekend me and the wife are going for a 12 miler which consists of running around the Great Orme twice. We did this in November last year but we only went round once. This is going to be a training run in preparation for her Snowdon Marathon attempt this year.
