Did my longest ever cycle ride (without stopping) today: 34 miles at about average 15 mph. I've put this in the Beginners areaas it is small beer to the more experienced cyclists. I was on a single-speed/fixed wheel and cycled anti-clockwise around Richmond Park a few times. I have plans to cycle commute to Brighton when I have a meeting there (and return the next day) so need to know how comfortable I would be. At the end of my session the area just below the back of my neck REALLY hurt; my hands REALLY hurt: my knees started to hurt when I braked with my legs. I couldn't have carried on. But I feel so pleased at completing the session, though I am still aching. My legs are developing muscles galore. And it means I can have a decent drink today as well now, with a clear conscience (I'm off to Twickenham to watch England vs Barbarians). Guess carry on practising is the mantra. And maybe get something to support my knees as well.
