I'm the youngest in our CTC group by about 25-30 years. I think the oldest, J, is 76. they are all strong riders, but J recently caught Lyme's disease and has been very poorly, his pace has slowed quite a lot as a result. M is also not far off 76 and is a very strong cyclist. He can keep pace with me easily. He broke both his ankles when he was 68 rock climbing. His daughter has now banned him from climbing but he still sneaks to the climbing wall when he thinks she won't find out.
