From a cycling club's website: General Etiquette Ride steadily. Keep a steady line and constant speed while in a group. Any sudden change is magnified as it reaches riders at the back and so can have dramatic consequences. No racing. You can race to your heart’s content in organised competitive events but please not on group runs. Do not overtake the rider/riders at the head of the group. If you have to, then do not push your way back into your original position but rejoin at the back of the group as soon as possible. Ride two abreast where it as safe to do so but always be prepared to single out when necessary. Ride immediately behind the rider in front - do not overlap either forwards or sideways. Overlapping forwards gives you no chance to avoid the rider in front if he swerves or falls, and overlapping sideways results in the group presenting a three abreast profile. Never ride more than two abreast. When approaching a hill anticipate the gradient and change gear in good time. Missing a gear change on the steep bit can bring you to a sudden halt - not a good thing for the riders behind you! Ride safely at all times. Follow the requirements of the Highway Code as they apply to cyclists and guidance from your leaders. Treat members of the group and other road users with courtesy. Acknowledge with a wave courteous behaviour by other road users. (Many oncoming motorists will slow down or stop when they meet a large group of cyclists, whilst others allow the whole group to join or cross a major road). Do not "wave through" a following vehicle that is waiting to overtake - let the driver make this decision. This will avoid the risk of being held responsible if the overtaking results in any form of accident. Do not react to bad driving incidents with gestures or provoke retaliation. Remember a road rage motorist has a one ton weapon! Ride with the group which best suits your ability. It is usually better (and less embarrassing) to start low and build up. If in doubt senior club members will be happy to advise. It is sometimes nice to try an easier group, especially if you are a bit off colour. It is considered bad manners to hold back a strong group when an easier group is available. Visitors and potential members are welcome to try the rides free of charge but should be encouraged to apply for membership. http://www.woolwichcyclingclub.org.uk/CyclingEtiquette.htm
