    • I've been internally debating if I should get a power meter to improve my running technique. Being a triathlete it is super helpful to have a power meter on the bike. I've had one for the last 3 years and at the time it was a hard decision to justify spending $1K on power meter pedals. But looking back at now it seems like a no brainer. Pretty much every single pro uses one in their training and racing to pace themselves and to track their performace.

      There are a few articles about running with power meter that I've read, but I wanted to see if anyone has any experience beyond just demoing it. I love trail running and this is where I feel it would be the most beneficial since elevation and terrain vary so much that it is hard to evaluate my pacing strategy.

    • The coach of Germany's world cup soccer team (they won) wrote a book I loved, Every Day is Game Day. They put power meters on the players and were able to show the players that power came from the hips more than the ankles, so they really worked on their cores.

      I saw a number of articles about them from people like DC Rainmaker in mid-2006, but I didn't hear much about them after among ultrarunners or their coaches. So I just assumed that for endurance runners, they didn't provide much value.

      Would love to hear other opinions.

    • The main concern I would have is how they measure. It is a relatively easy thing to equate power to performance on a bike, as you can just calculate rotational force, which is a direct input into the drivetrain.

      Running isn't quite the same though, discounting the fact that you use way more muscle groups for stabilization and support, footfall and stride could change how effectively your power translates into forward momentum. Not to mention variation in uphill / downhill. I suspect that you could get a pretty good equation of power to performance if you don't change your stride, and test on a consistent surface like a track; but I'm not sure how that translates into interval training like it does in cycling.

      A skeptic I am, but as an aspiring runner it would be cool if it magically works how I want it to :)

    • Power meters for running focus on helping you reduce your overall power exersion over the same effort. The power output numbers supposed to highlight when and where you are wasting energy with poor technique. In cycling the power meter measurements are much clearer to translate to real effort so the more power you can produce for the given effort, the better you'll perform.

      To sum it up: Running power meter focuses on power efficiency, while cycling power meter focuses on power generation.

      I would recommend you to try Stryd foot pod. Heard good things about it.
