Up until now, running power was practically only available to elite runners and would cost $10,000+ USD to measure in a lab. But we knew that performance-oriented runners would use power — only at an affordable price — so we decided to get the price down so low ($199) that Stryd will pay for itself 3 times in one year of running.

Yes, Stryd will pay for itself 3 times in just one year of running.

How? Here is our astonishing proposition:

  • - Stryd will ‘upgrade’ your GPS watch to an unseen level so you will have no desire to buy a new watch ($300+ value)
  • - You will satisfy your racing desire more frequently with ground breaking results with Stryd’s power pacing -- no more wasted races ($120+ value)
  • - Save time planning for a race course — no more fiddling with course recon, printing pace bands, or making special trips for practice runs ($75+ value)
  • - Your next running book comes free with Stryd: access expert form-enhancing run drills, race planning webinars, and training plans with your purchase ($161 value)

That is just the tip of the iceberg. If you promise to report your results to us in the first 30 days of running with power, we are prepared to ship you Stryd for just $199 today.


    Our one year warranty (two years in the EU) keeps you running with power.


    No worry returns. Just email us in the first 30 days!


    Stryd ships worldwide. Our technology is used in over one hundred countries. (No additional taxes for EU orders.)


    "At $199 I think that Stryd is good value for money, and it's one of the few devices that I would replace unhesitatingly if I lost it."


    "We like the simple number (power) that shows how hard you’re working."


    "A power meter can help you establish and maintain the correct pace, even on courses where establishing the right rhythm is difficult."


What is Stryd?

Stryd is a wearable that snaps on to any shoe.

It measures your running power and sends that to your watch (Garmin, Suunto, Polar, Apple Watch) when you are running.

What is power?

Imagine you are running on a track and you have a car driving at a constant pace in front of you.

The car is pacing you! If you follow the car, you will evenly split the run.

Now, imagine if the car began driving up hill.

Would the car keep going the same pace?

No, it would slow down.

You can see that the car is not trying to keep you at an even pace now.

It is trying to keep you at an even power.

It wants you to be able to evenly pace yourself up and down hills.

Even pacing is a lot more than just running the same speed in a workout or race.

Even pacing is actually about running at an even power.

Think of Stryd like the car.

Stryd will tell you a power number that you can keep up with on any terrain.

You can easily monitor your watch or phone to see if you are at the right power target.

With Stryd, you will never fall off or exhaust yourself during a workout or race because you will be running to your limit, but not over it.

How does it help me?

Do you want to run your next race faster?


Good. We can help.

Power is a direct measure of how much energy you use when you run.

We want to train your body to be able to access more power when you run.

If you can use more power when you run, you can run faster.

Stryd tells you a personalized power target for every run.

Each power target is designed to improve your endurance, strength, and speed in training.

Some runs are designed to improve your ability to run long.

Some runs are designed to improve your ability to run frequently.

Some runs are designed to improve your ability to run fast.

We identify your weak spot and instruct you to do specialized training to shore up that area.

If you followed a our training recommendations, you will consistently and predictably run faster.

What about race day?

We design a power target that pushes you to your limit on race day.

The power target will ensure that you evenly split your race so you have your best shot at hitting your personal record.

Overall, power is the best way to train and race because it trains you to your limit.

Why is power important? Can’t I just use pace?

Pace is very important. It tells you how fast you are running.

However, pace is not the best metric for training and racing.

To train and race effectively, you need more. It is not enough to just run fast.

You need to factor in hills, your fatigue, your speed, and your running form.

Power accounts for each of these factors so you train effectively when you:

- Have to run uphill/downhill

- Become fatigued late in a run

- Improve your running form and eficiency

What does this mean?

The answer is that you do need pace to train.

But pace offers a very one dimensional view into your run.

If you want a full view of your run, you need to measure your power.

Why is this better than heart rate and GPS?

GPS and heart rate technologies are good measurement tools, but they suffer from one fatal flaw.

GPS and heart rate are very good at telling you how your run went.

But they are not very good at telling you what you should do while you run.

Heart rate and GPS are not very responsive.

Heart rate lags.

GPS can be slow to respond too when you change pace or run up and down hill.

They are not effective at guiding your training in real time.

Stryd uses new motion sensing technology that transcends GPS and heart rate to give you instant access to information that you can you use when running uphill, downhills, and when fatigue starts to kick in.

This gives you access to real time information that your competition does not have.

You can make real time decisions during a training session or race to improve your training instantly.

This is the first time I have heard of this. Is running power new?


It has been around a long time, but this is the first time you can access it.

Scientists have been using running power in the laboratory for years to great effect.

However, they never figured out how to take it outdoors where people really train.

Stryd is the first to create a device that is small enough that you can run with.

A small subset have been using run power for years.

Now, it is available to everyone at a price affordable to runners.

When was the last time you felt like a million bucks at the finish line?

No, really. When did you truly feel like a million bucks? Think back.

Envision the perfect race day. You followed your plan religiously. You crushed your personal record by 20%+. The entire race day exceeded your expectations. You walked out of the finishing chute to endless high fives because everyone knew you had done it.

Has it been a while? A bit too long?

There are tons of runners suffering, just like you. You see tons of them every race. They are hunched over after the run, gasping for air, and barely able to talk. Totally burnt out of energy. Totally powerless.

They pushed themselves over the limit. They went way over their limit to the breaking point. Once a runner “breaks”, they cannot put themselves back together in a race. Their day is over.

Let's say it like it is: race day is chaos.

Injury risk skyrockets when you “break.” That is when you damage your muscles so much that you need weeks to recover. The discomfort of running is immense. You can barely salvage a gritty jog to the finish line to save face.

It is not your fault either. The excitement of race day will pull even the best runners into running over their limit.

It is time to get back to that “million bucks” feeling...

to close out a race strong...

to know you made good on your training...

to look at the clock at the finish line and fill with pride.

The solution? Stryd's power meter.

Stryd measures the exact amount of energy you exert at any given moment. You learn how to run to your limit, but not over it. Power adapts to any race course in real time, so there are no unexpected surprises. With Stryd, you can predictably turn in excellent race results instead of "breaking."



    "I used Stryd in training it really helps keeping in the right zone. Stryd provides great coaching guidance."


    "The holy grail in running has been to discover such a factor – measuring power in running as a unit."
