Each athlete tries playing to his/her strengths. Some prefer to go early and attack from the front. Sir Chris Hoy, who started his uber successful career as a kilo rider, coined the term “Hoy Attack” by taking and never surrendering the lead. Other riders, however, may choose to sit in and accelerate with 1/4 to 1/2 lap to go. At the international level, top speed exceeds 70kph.
