Running clubs typically organise regular club runs, often with a social element, organise track training sessions and coaching, liaise with Athletics UK, inform members about events and races, enter teams in team events such as relays, provide information to members, organise social events, and organise races. Most of all, they link runners with other runners. Look around to find a club that suits you. You can look at a comprehensive list of London running clubs , and our links page has links to many of their websites. All clubs will welcome visitors - just show up for one of their runs and see if you like them.
Some clubs tend to be quite serious, some less competitive.
You do not need to join a club to enter a race. All races allow entrants who are not a member of a club, though there is a surcharge on the entry fee. But if you enjoy racing, remember that it is only because of the unpaid efforts of club volunteers that there are any races to run in. You might want to join a club to give something back to the sport. For most road races, clubs do not select a team.
