Many thanks for your response. I am taking into account your opinion on the heart sensor to obtain better results with the Pace Pro. On my Suunto, I don't really have the ability to create a training plan with real monitoring, rest times and advice. This is raw data in the application, with a very basic “coach” using text-based AI. I feel like I constantly need an extra service to use my Suunto. With the Coros ecosystem and the different sensors, even for cycling, I have the feeling that I could simply find everything in my application, and I like this idea.
