Cycling Time Trials is the bicycle racing organisation which supervises individual and team time trials in England and Wales. It was formed out of predecessor body the Road Time Trials Council in 2002.
A time trial tests a rider not against other cyclists but the watch. Other than in team events, which are less numerous, competitors race individually, starting at intervals of a minute or more. Riders may not ride together when one catches another. The order of start is often organised so that the fastest riders are spaced apart. In that way they are less likely to catch each other while, when they catch lesser riders, they will pass that much faster that neither will be helped or hindered.
UK races can be organised over any distance but in practice they are most often run at standard distances of 10, 25, 50 and 100 miles with occasional races at 30 miles. The winner is the fastest over the course, routed so it finishes close to the start to lessen the effect of hills and wind. Longer events, lasting 12 or 24 hours are also held, the winner covering the greatest distance.
There are records at all distances, for riders on conventional bicycles, tandems and tricycles (and teams of individual riders, calculated on aggregate times or distances). There are championships for men, women, riders younger than 18, and competitions for veterans (riders aged 40 or more). The British Best All-Rounder competition, run by the RTTC since 1944, combines performances across three longer distance events.
In 1890, the National Cyclists' Union banned racing on UK public roads in fear of a ban not just on racing cyclists but all cycling. The legal position of cyclists was not secure. The cycling historian Bernard Thompson said: "Events organised by clubs in the 1880s, although taking place on quiet country roads, were constantly interrupted by the police. Often horse-mounted policemen charged at racers and threw sticks into their wheels."
The NCU asked clubs to run races on closed tracks, known now as velodromes. But few existed and so rebel races began, under the influence of men such as Frederick Thomas Bidlake, to continue racing on the road but in a way they believed need not bring police attention. Riders would start at intervals, usually a minute, and race against the clock. Riders meeting on the road were not allowed to race against each other. Unsure of the legal situation, riders dressed from neck to ankle in black to make themselves less conspicuous, never wore numbers but always carried a bell. Races started in the countryside at dawn on courses referred to only in code. Even the cycling press was asked not to say where a race was taking place and details to competitors were headed "private and confidential" up to the 1960s.
