i thought this would be easy as I've done a few 10ks on and off Road. That will teach me for being cocky! It was lovely, long, up and down and tough. The up and downs were at each lock, some with steps some just a little hill but my goodness when you've done a couple you feel it. Needless to say I loved it, will definitely book it again for next year. One water station, excellent marshalls, lovely medal and goody bag and a bus back to start - perfect!
