My wife and I are getting on, but getting back into riding on the road. We were nervous about the speed and closeness of traffic and the longest ride we had done was about 8 miles - until we discovered the local U3A (University of the Third Age) cycling group. All "getting on", welcoming and experienced. The first ride we went on was 22 miles, the speed of the group being the speed of the slowest rider, with an hour for lunch, and we had a great time. So now, once a month, we do a 20 mile plus ride in company which we really enjoy. Motorists seem a lot more careful if there are 10-15 of you, and I have yet to see anything like the close overtakes I have experienced when riding alone. We are near Malvern, but there will be a U3A near you, they are a great idea and often have a cycling group..
