Running Stress Score

After each day’s workout, we all wonder — how was my workout today? Have I done enough? Did I push too hard? Indeed, consistent training with the correct load and variety spurs the best physiological improvement; the secret sauce to how top runners build fitness quickly, to run faster. This is why we designed Running Stress Score (RSS), a single number to help runners understand their day-by-day training. It quantifies how much you’ve trained and…

A look back at Kona 2016 : Alessandro Degasperi

We'll be watching the NBC broadcast of the 2016 Ironman World Championship on Saturday at 2:30ET. When you do, be sure to be on the look out for Bib number 35, Alessandro Degasperi. On a day when five athletes ran their marathon under 2 hours and 50 minutes, Alessandro quietly ran one of the fastest marathons of the day. He passed by more than 20 of his competitors during the marathon and completed it in…

Stryding to the Summit: Lionel Sanders sets the Ironman World Record

Lionel Sanders broke the Ironman World Record at Ironman Arizona in a time of 7:44:29, merely 5 weeks after his worst race of the year. His data from Stryd provides unique insights into his historic day.

(Phoenix, AZ) Lionel Sanders emerged from the water after 53+ minutes of swimming in 25th place. Next, after four hours and 112 miles in the saddle, Lionel entered the run in second place and within range of the Ironman World Record.


Lionel had been here before, however. Five weeks earlier, at the Ironman World Championship in Kona, Lionel used a strong bike to put himself into 13th place at T2. This was close enough that, with a strong

Run Faster with STRYD: Part Five

Supplemental Training

With the recent release of our new Stryd power meter, we are more excited than ever about the possibilities of helping people run faster. Our recently released white paper (download it here) discusses running economy – a measure of the metabolic cost of running – how it impacts performance and how you can use Stryd to help you run faster.

Many runners avoid the gym at all cost, so the mere words “strength training” are enough to make any runner uncomfortable. But what if we told you strength and plyometric training could make you faster? An abundance of research would agree -- many have found that the implementation of plyometric and/or strength training routines can improve running economy, Leg

Run Training

With the recent release of our new Stryd power meter, we are more excited than ever about the possibilities of helping people run faster. Our recently released white paper (download it here) discusses running economy – a measure of the metabolic cost of running – how it impacts performance and how you can use Stryd to help you run faster.

Last week, we talked about using Leg Spring Stiffness and Form Power as indicators of running economy. Here, we focus on how to improve LSS over time.

One of the most underutilized types of training by the majority of the running world is simply running fast. Incorporating short, fast runs of 100-600m in length are a great way to hone

Run Faster with STRYD: Part Three

With the recent release of our new Stryd power meter, we are more excited than ever about the possibilities of helping people run faster. Not only does Stryd measure how hard you are running, but it also measures how effectively you are running. In our recently released white paper download it here we discuss running economy – a measure of the metabolic cost of running – how it impacts performance and how you can use Stryd to help you improve it.

Leg Spring Stiffness and Form Power

In many ways, running economy has remained somewhat of a mystery due to the fact that it is effected by numerous biomechanical variables. We mentioned many of these in Part Two of this series. Reasearch

Run Faster with STRYD: Part Two

With the recent release of our new Stryd power meter, we are more excited than ever about the possibilities of helping people run faster. Not only does Stryd measure how hard you are running, it also measures how effectively you are running. In our recently released white paper (find it here) we discuss running economy – a measure of the metabolic cost of running – how it impacts performance and how you can use Stryd to help you improve it.

Biomechanical Variables and Running Economy

Our first post in the series looks at the concept of running economy. Running biomechanics have long been considered to play a primary role in determining one’s running economy. It is generally accepted that most trained

Running Economy

Runners are commonly categorized into “types”: THE SPEEDSTER, THE MEDITATOR, THE TRAILBLAZER... With Stryd, no matter your type, you can RUN FASTER. The recent release of our new Stryd Power Meter, has us more excited than ever about the possibilities of helping you to do just that. Not only does Stryd measure how hard you are running, it also measures how effectively you are running. In our recently released white paper (download it here) we discuss running economy (a measure of the metabolic cost of running), how it impacts performance and how you can use Stryd to help you quickly, and more effectively, make improvements.

For runners looking to improve their performance, enhancing running economy has been a

First Stryd Run With Matt, Triathlete & Software Developer

Overview of my Run: Power, Pace and Elevation

As a data geek, I liked the idea of collecting more data for my run. At least as a curiosity.
I collected a foot-pod - kindly lent by Stryd - a couple of days before the race, but I was only going to let it record data, and not attempt to change any settings on my watch to display any field that would confuse me during my race.

The pod wasn't perceivable at all on my shoe, and that unobtrusiveness is what convinced me to try it. I don't think I would have tried with the chest strap. It was only a case of clipping it on my laces and forgetting about

Stryd In Kona: Learn From Top Kona Pros To Race With Power

On October 8th, 2016 more than 2300 of the world’s most elite triathletes converged on the Island of Kona to compete in the iconic Ironman World Championships. Among them were a select few who were the first to run with the new STRYD power meter foot pod. The new STRYD power meter collected information about effort and efficiency that has never been recorded by athletes competing at the championship level.

After swimming 2.4 miles and biking 112 miles, the athletes run 26.2 miles—a marathon—in torturous conditions. Running in the mid-day Hawaii sun, temperatures surged to close to 90 degrees with high humidity and black volcanic rock lining the course only intensifying the heat. Not only
