Running is a lifelong sport, empowering passion and improvement for everyone, every day.
We invented Stryd, world’s first wearable power meter eco-system for running, to empower everyone to train effectively, run efficiently.
Go beyond barriers. Run faster.

Power is the direct measure of an athlete’s physical capability. It is the objective quantification of energy output regardless of body type and external conditions.

Using a tiny device clipped onto the shoe, Stryd measures data at lab-grade power when you run. Using power as a metric, Stryd understands how fast you can run (fitness), how long your can run (muscle endurance), and how well you run (form and efficiency). It then guides you through purposeful training, efficient running, and faster racing.

Run Faster

How fast you can run is governed by key fitness metrics, in particular, lactate threshold and VO2Max.

Stryd offers accurate measurements of your running performance at both lactate threshold and VO2Max. It then automatically derives personalized training zones tailored to your fitness level, and further adapts the training zones as you progress. With this data, you can train consistently and purposefully, lifting your limits and enabling you to run faster.

Run Efficiently

Running efficiency is defined as the energy expenditure at a specific running pace. Power over time is energy, hence the direct measure of how efficiently you run.

Stryd quantifies your total energy demand and the energy that you can recycle due to your form, muscle control, strength and condition. Follow the prescribed workouts, plyometrics, drills and weight training, and you can run faster with less power to go farther!

Run Longer

How long you can run is governed by muscle endurance, or the length of time your muscle can handle the step-by-step impact of running while consistently producing power without reaching fatigue.

Stryd quantifies your muscle endurance by measuring the change of your power output and identifying the level at which you reach fatigue. It then prescribes workouts that guide your muscle endurance development step-by-step so you never push the envelope too early or too fast. This prevents injury so you never quit before reaching your goal.


Running consistently while aligned with your threshold is the secret to reaching your new personal best.

Stryd makes your race day simple. Using power, the optimum racing strategy is to follow a number that remains constant regardless of the terrain condition. When you run guided by a single, targeted power number from the start of the race to the finish line, winning your own race cannot be simpler.

Stryd has become a key part of my training, perhaps the central part. Running with power has helped me to know myself better as a runner, and to set and train towards appropriate goals.

A recreational triathlete/runner, who trains himself and reads a bit of training, can benefit a lot from using Stryd. I am also overwhelmed with the enthusiasm and responsiveness of the Stryd team.

I paced by power - numbers I trained with and expected to see, and had near perfect mile splits. And as a result, I never hit the wall.

Running with Stryd helped me to keep my early efforts in check, and as a result, I was still running strong late in the race.
