What is Stryd?

Stryd is the first wearable device to give runners an accurate measure of power.

Stryd uses revolutionary sensing technologies to measure a runner’s movement through 3D space and track the environmental conditions of the run. From that, it gives runners an accurate, real-time power number.

For the first time, runners can accurately measure workout intensity across any terrain. From that, the possibilities are endless.

Why did you build Stryd? What problem are you taking on?

More than 20 million US runners will train using some kind of data this year. Pace tells them how fast they’re going and heart rate helps to evaluate effort. But, both of those metrics vary widely based on conditions and terrain.

Without an objective measure of performance, runners of all abilities struggle to stay on track. Poor pacing leads to “blow ups,” overtraining leads to injury and lack of measurable progress leads many beginner runners to give up running all together.

How is Stryd different from what is currently available?

Stryd is the first device to give runners consistent data to help them run better. Using power, the only consistent, terrain-independent measure of run performance, Stryd eliminates the guesswork from run training and racing.

Power-based training is already the gold standard for improving performance in cycling, but until now it has only been available on a bike. Stryd uses patent-pending hardware and algorithms to determine power. It provides runners real-time data on the watches and mobile devices they already use in their training.

Tell us your founding story. Was there an “ah ha” moment?

Three years ago, Stryd started as an idea to improve the metrics athletes use to train and compete. We quickly found that runners had a data problem. While they’re getting more and more data about their runs, they lacked a consistent baseline to understand all that data.

Over and over again runners, coaches and experts told us that there had to be a better way, but they hadn’t seen it. So, we went in search of a better metric, and we found cyclists who told us power had changed how they train and race. That’s really the “ah ha” moment for Stryd.

Calculating power for the human body was hard enough. Doing it on a small, durable device runners would actually use was harder. So, we began working with a select group of advisors from the running and triathlon community. We built devices, tested them, re-built them and re-tested them.

A lot of things had to be pushed to the limit: dense sensor integration, signal processing algorithms, heroic battery power management techniques, and sophisticated signal processing algorithms capable of running a computer smaller than your thumbnail.

A half dozen prototypes later, we had it. Tiny, unobtrusive power for runners.

Tell us about your founding team and their backgrounds.

]Success in wearable technology requires a unique blend of expert engineers and domain-specific business leaders. Stryd has paired proven engineers with successful business leaders to bring this unique product to market.

On technology side, Robert Dick is author of more than 100 research papers, with his technology used in NEC smartphones, he is an expert on embedded systems and a professor at the University of Michigan, Ann Arbor.
Li Shang is the former chief architect for Intel, and one of the premier embedded systems engineers in the world and a professor at the University of Colorado, Boulder.

On business side, Eric Olson has held executive roles at three successful early-stage technology startups, including Active.com and currently works extensively in the triathlon and running space. Gus Pernetz was both an elite coach and a successful sports entrepreneur, and has been responsible for engaging the running industry in the development of Stryd.
