Imagine sprinting toward a wide mud puddle on the trail. If you stop to jump with both feet, you lose all your speed and get soaked.
Instead, your body naturally stretches into a leap—taking off from one foot and landing smoothly on the other without breaking stride.
How do elite athletes turn raw sprint speed into a massive, floating leap across open ground?

The Three Phases of a Leap

A great leap is an extended running stride with a prolonged flight phase, where both feet are off the ground at the same time.
The entire movement breaks down into three key moments: the takeoff plant, the flight extension, and the rolling landing.
What keeps you from crashing into the ground on that one-foot landing?

Converting Speed into Distance

In 1687, Sir Isaac Newton showed in his third law of motion that every push against the ground creates an equal push back into your body.
When you plant your takeoff foot, driving down and backward produces ground reaction force, which launches your body forward and upward.
To get maximum distance, you need a shallow takeoff angle between 20° and 30°—too high wastes energy going up, while too low cuts your airtime short.
