We would add:

It’s a good idea to develop your group riding and bike handling skills by joining a club that offers either structured training sessions on one of the region’s closed circuits or outdoor velodromes. Or by taking part in cyclo-cross. Most of the region’s Go-Ride clubs offer structured training and group rides on the road, which are an ideal way to hone your skills. These can be found via the British Cycling club finder or via this website’s club finder.

It’s a good idea to get some bunch time at one of the region’s three closed circuits,  while the Thursday evening handicaps run by the SSSCCRRL http://www.sssccrrl.co.uk are an excellent introduction to racing on the open roads for beginners as the riders compete in smaller groups, based on ability. So there is time and space to build your skills and fitness before taking on a Sunday road race.
