We’ve all heard that if you want to improve your running game, you should target a stride rate of 180 steps per minute. We’re not convinced. Our favorite example is our head of engineering. At 6’5” we’re pretty sure a 180 stride rate is a physical impossibility. We took a look at data we captured at the 2015 TCS NYC Marathon to look into … Read More

We discovered flight ratio is much more strongly correlated to finish times than the infamous 180 … Read More
