Description:

Form Coach shows you how to improve your Running Economy, provides the real-world performance benefits you could see and guides you through the process by creating personalised form workouts.

Working on your Cadence can help you improve your speed and run more efficiently. It could also reduce the impact on your body as you make contact with the ground, potentially reducing your injury risk.
Running with optimal Step Length can help you run more efficiently and boost your speed. Runners who overstride – when the foot lands too far in front of the body – can suffer recurring injuries, so working on your Step Length could help keep your running strong, too.
Control your running despite external factors changing. Running Power is a measure of real-time effort and the rate of energy being expressed at any given moment.

NURVV Run’s Pace Coach guides you to run to a chosen pace by optimizing your cadence and step length – the two metrics that together determine your pace. Simply choose the pace you want to run at, and Pace Coach will create a workout with cadence and step length target zones based on your unique running form.
