It took Jason Kenny, the Olympic gold medalist in the track cycling, about 90 seconds to complete his first lap. That's about how long it would take you to jog the same distance. It's not that Kenny can't bike faster: in full sprint he travels nearly 50 miles/hour. So why does Kenny go so slow at the start?

Explanation:

At the beginning of a long race, if one starts running or cycling too hard, the body will go into an anaerobic state. This process produces lactate. This causes fatigue sooner and in order for Jason to get his body into an aerobic state, he would have slowed down dramatically in order.

This justifies why the professional marathon runners start relatively slowly and once their body gets adjusted to aerobic state they start to sustain consistency and begin accelerating.

A situation whereby the body has sufficient oxygen to provide to all the necessary muscles in the body is referred to as Aerobic running. This is crucial for a long sustainable race. This is why Jason Kenny begins relatively slow.
