What if there was one number that could finally help people run BETTER?

Every day, millions of people run. We run to stay healthy. We run to compete. We run for the love of running.

Yet, run training can be frustrating. While runners have metrics to guide them – from pace, to heart rate, to perceived excursion – the variability and complexity of those metrics leads to inconsistent results. Runners over-train. They fail to see progress. And they get injured at a higher rate than any other sport.

So, we thought…. what if there was one number that could finally help people run better?

And, we found it. Power, the only consistent measure of workout intensity, has long been the standard for training in cycling. A bike’s drive train is consistent, though. A human body isn’t. So, while measuring run power has long been viewed as “the holy grail” for runners, it has been elusive. 

Until now.

Created by Princeton engineers, Stryd is the first wearable device to give runners an accurate measure of power. So, for the first time, runners can accurately measure workout intensity across any terrain. From that, the possibilities are endless.

To use Stryd, runners simply clip it to a pair of short and run. It's tiny, out of the way and it automatically syncs with BOTH the sports watches and mobile phones people use to train every day. 

From the first run, you'll see new ways to improve your run. And, you'll quickly...

What People Are Saying:

At Stryd, we’ve been lucky enough to have support from some of the biggest names in endurance sports. It’s really exciting to us – and to them – that the triathlon and running community shape how this technology is used day-to-day in training and racing.

Stryd: The World’s First Wearable Power Meter

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.

Synced Up. Ready to Go.

Stryd is easy to use. Just clip it on – and go. There aren't any buttons to fiddle with. Instead, it's simply always working. Stryd automatically captures your run and syncs data with all the devices and applications you already use to train.

  • Sports Watches (Stryd uses both Bluetooth Smart and ANT+. Stryd supports sports watches that support power, e.g., the Suunto Ambit series, Garmin XT series, and Megellan Switch series. For sports watches do not support power, Stryd can display the running power through other channels, e.g., heart rate or cadence, but is a little harder to use than watches that directly support power.)
  • Mobile Devices (iOS, Android)
  • Computers 

Set Goals. Get Guidance. Track Success. 
Stryd connects you to the world's best coaches and training platforms and athlete communities, track your data, compare yourself to friends and watch your progress. 

Lab Tested. Real World Perfected.

Stryd has been tested in top sports science labs and used in the real world by elite coaches and professional athletes. When you support us on Kickstarter, you become part of the community that will shape the future of power-based run training.

Stretch Goal #1: 1000 backers

Power-Based Training Programs from Top Coaches

When you support us on Kickstarter, you support the community that will bring power-based training to the running world. 

The next step is building power-based training programs for all triathlon and running distances. We’re working with top coaches to do exactly that, and your support will get us to the goal event faster.

  • Triathlon programs for sprint, Olympic, 70.3, and Ironman distances.
  • Running programs for 5K to marathon distances.
  • Two- to Six-Week programs to improve sport-specific strength, form, and fitness.

Inside Stryd

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.

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. Stryd was built with the help of this passionate running community. Now, we’re ready to expand our reach and work with 1,000 more runners who will help shape the future of power-based running. To be one of those people, just support us here on Kickstarter.

We Are Stryd 

Measuring running power isn’t easy. Doing it well required a unique team of talented embedded systems engineers and passionate endurance sports enthusiasts. Stryd was born in Boulder, a center for athletes and technologists, and it unifies these two callings. 

We’ve been lucky enough to have support of our amazing team and some of the biggest names in endurance sports. But, now we need YOUR support. Stryd is giving runners a simple way to run better. But, YOU will define what that means for the sport. Like any new technology, the people who use it will shape its future. THIS community will build the future of power-based run training. We need your help to pay for production and materials – and we need you to tell us how you’re training and racing with power. When you support the world’s first wearable power meter, you support the future of this great sport.

Production Timeline

Risks and challenges

This Kickstarter campaign aims to introduce power-based training to the running community. Even though it has long been the standard for training in cycling, power is new to the running world. There is no prior knowledge how to use power to guide day-by-day training and racing. Such knowledge needs to be created and then disseminated among the running community. We believe this is the biggest risk of bringing power, such a disruptive metric, to running.

This is also the reason why we launch this Kickstarter campaign. Over the past three years, we have been working with runners, coaches, and sports physiologists in the Boulder area. Kickstarter offers a great platform to reach the running community worldwide. Through this campaign, we would like to work with runners worldwide to collect and analyze running power data. We would like to support coaches and sports physiologists to investigate and develop power-based training programs. We would like to collaborate with third-party training platforms to disseminate power-based training knowledge to everyone who wants to run better, faster, and safer.

Another potential common risk in the wearable space is hardware fabrication. Our team has been working with multiple reputable manufacturers in China since 2011. Our hardware engineers spend many months of their time each year in China, working with the ODM/OEM engineers on the same manufacture floor. We do not foresee further challenges on the hardware fabrication side. We promise to do our best to deliver Stryd with high quality in the summer.

FAQ

  • If you want a Stryd device in 2015, Kickstarter is the only way to get it. We do plan sell through other channels, but not until 2016.

    Last updated:
  • Stryd uses both Bluetooth Smart and ANT+. Stryd supports sports watches that support power. For example all Garmin XT, Magellan Switch, and Suunto Ambit series watches, except the Suunto Ambit 2R (which doesn't support power).

    For sports watches that do not support power, Stryd can display the running power through other channels, e.g., heart rate or cadence, but the user experience with watches that explicitly support power is better.

    Last updated:
  • Yes. Stryd imports and exports training data using standard TCX and FIT formats. Stryd also supports third-party training platforms, such as TrainingPeaks, GoldenCheetah, Addaero, Final Surge, Suunto, Garmin, and Strava.

    Last updated:
  • Our position is one of openness. It is our goal to support the tools runners use now. We are open to collaborating with sports watch and web-based training platform companies and are in discussions with several now.

    Last updated:
  • In addition to power, Stryd has the capability to measure a range of running metrics such as cadence, impact, and running efficiency (economy to sports physiologists).

    Some metrics will be stored for later review, but not displayed on a sports watch, to keep the in-run user interface simple.

    Last updated:
  • We are collaborating with coaches and sports physiologists to develop power-based training programs. We will collaborate with third-party training platforms to make power-based training information available to everyone who wants to run better, faster, and safer.

    Last updated:
  • The current version of Stryd may be useful for any sport involving running, although our current focus is endurance running.

    Last updated:
  • Running power can be reported in unit weight power (watts/kg) and total power (watts). Stryd can report relative (watts/kg) power without knowing body weight. Relative power can be used directly in training, and for athletes with different body weights to compare their power numbers. Stryd needs body weight to report absolute total running power (watts).

    Last updated:
  • Yes.
