I'm now in my sixties, my pace has dropped off a bit, though my endurance is still good, the clubs medium paced ride that was my regular ride is now on the upper limits of my abilities and what I want from cycling has changed, I know how fast I can go and I'm not interested in testing that, if I was I'd turn up on the club TT, I no longer want to spend my Sunday mornings blowing out my arse whilst hanging on to a wheel at high speed, I want to see the country side a bit. I still like a challenge now and again but these days that challenge would be successfully completing an event, I still train a bit in the winter, but I'm not as serious about it as I was and its more about keeping my fitness when bad weather is restricting cycling than making improvements.
