I once competed in a one-hour track race on a cinder track. They used to be quite popular many moons ago. Being a lot younger and ftter than I am now I ran 17221metres (just over 43 laps, 10.7miles) - though I spent much of the race in Lane Two. I often used to do 5x1mile on the track back then and never got bored, but I rarely do track stuff these days.
