Flight Time Explained

In brief: Flight time is the part of the running stride when neither foot is touching the ground. It is what separates running from walking. More flight time generally goes with a springier, faster stride, but it also means a bigger landing to absorb.

What is flight time?

Flight time is the phase of each running stride when both feet are off the ground at the same time. It is the defining feature that separates running from walking, where one foot is always in contact. It pairs with ground contact time to make up the full stride.

Why it matters

More flight time usually reflects a springier, more powerful push-off and is associated with faster running. However, every period of flight ends in a landing that the body must absorb, so more airtime also means more impact to manage. It is a trade-off rather than something to simply maximise.

How it is measured

Flight time is measured by advanced running devices that detect exactly when each foot leaves and meets the ground. Comparing flight time with ground contact time gives a picture of how springy and quick your stride is.

What to look for

Flight time tends to increase naturally as you get fitter, stronger and faster, rather than being something you force. Strength and good form let you spend more time in the air efficiently without battering your legs on each landing.
