Negative split

A negative split is a racing strategy that involves completing the second half of a race faster than the first half. It is defined by the intentional setting of a slower initial pace, followed by a gradual or sudden increase of speed towards the end of the race. Alternate strategies include even splitting (racing at a steady pace) or sit and kick (also known as a sprint finish). Conversely, the act of completing the first half of a race faster than the second half is known as a positive split. The strategy of negative splitting has been documented in competitive running since the early 20th century. Runners such as Steve Prefontaine, Wilson Kipsang, and Galen Rupp have used it in races. Negative split strategies are also used in swimming (including Janet Evans's 1988 Olympic gold in the 400 m freestyle) cycling, triathlon and horse racing.

It takes self-restraint to allow others to run ahead and not be pulled along. Starting slow allows the runner's body to compensate for the lactic acid production and low oxygen levels that result from exertion. Lactic acid buildup may cause a runner to slow down unintentionally. Progressively increasing speed in any race allows the runner to focus on passing each person running directly ahead. ==References==
