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 or sit and kick. 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 them in races. Negative split strategies are also used in swimming cycling, triathlon and horse racing.
