It's meant to be the optimum cadence for the average run. I am only on wk6 (did R1 today), but tried to keep my stride fast and short, which is getting easier the more I practice. It makes the running much easier on my legs.
I can now breathe, keep my stride short, which keeps my pace fast, and remind myself to lean slightly forward all at the same time!
I am looking forward to running more to my own music, and already use a few tracks for my warm up. Is there an app which would help me organise the music I already have and find out which ones are 180bpm. Or is there some good running music anyone can recommend please? Thanks!
