Stryd
Stryd is a passionate company of runners who are scientists, developers, designers, and athletes who want to help you get the most out of every run. They developed the world's first powermeter for running that measures running effiency and offers personalized performance-enhancing training.
Stryd is a small portable powermeter that you can click on your shoe. It measures more than twelve different values such as performance, technique, muscle strength and fitness, just like the external environment, and adds these values together in one given power. The power is the key to monitoring training intensity (effort) and efficiency. Power has been a fixed value for years in cycling. Stryd now brings this revolution to running!
