I was planning on doing some experimenting next week to try to ascertain what running cadence feels "right" for me. I have short legs and I feel that I need to run at a high cadence to feel comfortable when running and much of the Podcasts and running music available is way too slow for me. I have a Metronome App in my Android phone as well as some music of different BPM's from Podrunner and I was going to use them in my experiment.
But now I have discovered RUNZI
It uses the phone's accelerometer to (among other things) monitor the beat of the feet and also measures the physical impact resulting from those footstrikes. This enables a more objective analysis of what impact my running form at different BPM's has (as well as the subjective feel that we all have when running)
Has anybody used it??
