... because I finished 10km in 58 mins 53 seconds!
Well, due to a technical hitch it was actually 10.27 km.
Between 1km and 9km I thought I could just keep going for ever. Obviously not really "for ever", but I think I was in what is known as "the zone". I felt fine in the last km, but I think I was just thinking a bit too much about just finishing that last km.
Beautiful warm sunny day - ran down on the sea front and it was lovely running along an almost flat route.
