Great Tool
I have come back to K1 racing rather late in life and realised that nobody wants to coach an older guy. So I looked and looked for a tool that would utilise all the amazing tech of my iPhone and provide me with real time and recorded workout data for post analysis of my progress ... This tool is really great and tuned correctly can pick up every stroke and heart beat .... I use it with iPhone 8 and the Scosche Rhythm+ HR armband. The phone is placed in a waterproof pouch attached in front of my cockpit using Velcro and I keep it attached to me via a lanyard. Great simple affordable! I use Trainingpeaks.com to view and analyse all my workouts and progress. Great App! Thanks to the developers!
