It is not a stage race, the clock never stops from the moment the riders leave the start to the moment that they reach the finish, so it is a long individual time trial. Riders must therefore strategically choose how much time to devote to riding, resting, and refuelling each day. Being self-supported or unsupported means that drafting is not allowed, receiving any form of support from other racers is not allowed, nor is it from friends or family; all food, accommodation, repairs, etc., must be purchased from commercial sources.
