![]() ![]() In single seater, open wheel racing series such as Formula One and the Ind圜ar Series, as well as to a lesser extent in sports car racing, a technique known as slipstreaming is used. A Wired magazine report that interviewed various experts affiliated and unaffiliated with Nike found they universally expected more coordinated pacing efforts to occur in running after Breaking2, with two of the quoted experts predicting that behavior like "cooperative drafting," or races that incentivize cycling-peloton-like behavior could improve running times. Nike worked with the aerodynamics expert Robby Ketchell at the University of New Hampshire to experiment with and select a formation of pacemakers that would best minimize drag on the professionals it sponsored in the project it termed Breaking2. Generally the effect is much less pronounced than in cycling due to lower speeds. It can also be competitive or tactical: one competitor will try to stay closely behind another, leaving the follower with more energy for a break-away push to the finish line.ĭrafting behind another runner can conserve energy when facing a headwind. Drafting can be cooperative: several competitors take turns in the lead position (which requires the most effort and energy consumption). Successively, each cyclist leads the group. In order to ride very fast, a team of some skilled cyclists may form the "Belgian tourniquet". Each cyclist, except the first, is drafting behind another one. ![]() When cyclists ride fast they form a paceline. ![]() In road bicycle racing, the main (largest) group of tightly packed cyclists in a race is called a peloton where cyclists ride in a long formation with each (but not the first rider) drafting behind the others before them. In cycling, any time one bicyclist is riding behind another, energy is conserved, especially at higher speeds. It is believed, but not yet conclusively proven, that thoroughbred racing horses draft each other, especially in longer races. Drafting also occurs in competitive longboarding. In a competition pool a swimmer may hug the lane line that separates them from the swimmer they are abaft of thereby taking advantage of the liquid slipstream in the other swimmer's wake. Drafting occurs in swimming as well: both in open-water races (occurring in natural bodies of water) and in traditional races in competition pools. Especially when high speeds are involved, as in motor racing and cycling, drafting can significantly reduce the paceline's average energy expenditure and can even slightly reduce the energy expenditure of the lead vehicle.ĭrafting is used to reduce wind resistance and is seen most commonly in bicycle racing, motorcycle racing, car racing, and speedskating, though drafting is occasionally used even in cross-country skiing, downhill skateboarding, and running. Drafting or slipstreaming is an aerodynamic technique where two moving objects are aligning in a close group to exploit the lead object's slipstream and thus reduce the overall effect of drag. ![]()
