Thanks for the post, Mark, and the added insight, Coach AJ.
High running cadence is something I’ve always struggled with (averaging low 70s pre-training plan). I’ve been using a metronome (Pulse app) on one run per week and am focused on/tracking my cadence on most other runs. I started my metronome at 85, since 90 felt way too fast and weird, and am up to 87. I am slowly but surely seeing some improvement and even averaged low 80s in a 10 mile race last week. Little changes applied consistently have definitely helped me!
