Very similar to a bicycle time trial race, at the IOM TT the riders startn at 10 sec intervals indivdualy ( a few years they used to start in pairs ) and it is the time taken to complete the given number of laps that is the deciding factor in who wins. The fastest riders usualy start first for safety and spectators can tell who is making up or losing time as the riders pass them, the comentary on the radio from three points round the course also helps to keep you informed.
