90/90 Running

Pegasus 90/90 Running

90/90 Running™ is a unique consulting service that combines very sophisticated measurements of running metrics with proven methodologies and coaching to improve performance.



There’s more to it than just your heart, mind, and logging miles. To run faster and reduce your chance of injury, know what your feet and legs are doing.


Ground Contact Angle

Land your foot at a 90 degree angle to the ground.
Ground Contact Angle (GCA) measures of the angle of the lower leg when the foot strikes the ground. Peak efficiency occurs at 90 degrees, which maximizes muscle elasticity and minimizes breaking forces.


Take 90 strides per minute.
Cadence is measured in the number of strides per minute. The optimal range is between 85 to 95 strides per minute.

Repeat Steps 1 and 2.

That’s Pegasus  and 90/90 Running™

Let the Pegasus Smart Training System guide you to what nature intended. 

It’s that easy!

“Pegasus allows runners and their coaches, of all levels, to fine tune their training, while being able to avoid injuries because they’ll be able to monitor the forces that might lead to those injuries before they happen. It’s unlike anything we’ve ever had in running before. Contact us to learn more about how to benefit from 90/90 Running, and see a redacted evaluation for improvement to see what is involved.”

Pegasus Performance Metrics


Ground Contact Angle

Measures the angle of the leg when your foot strikes the ground and tells you if you’re landing at a neutral position, overstriding or understriding.


Measures the number of strides per minute.

Ground Contact Time

Measures how much time, during the running stride, your foot is on the ground rather than in flight. Lower ground contact times indicates you are spending less energy each stride.

Kick Dynamic

Measures the speed of motion associated with lifting of the foot and lower leg during the back kick. Efficiency increases at higher KD values due to reduced energy required to advance the leg and foot forward.


Measures the change in angle of the foot from initial contact to midstance (where the foot is pressed flat against the running surface). Studies have shown that pronation angles of 5 to 8 degrees are observed in elite athletes.
