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.
