Spare me your "advice".
Who the hell sprints on a recreational ride anyway???

I have never in my life been close to my max heart rate, and there's no reason for me to be either.

I want to be able to ride long distances. Max speeds is not a bit interesting in this context. My dream is to one day be able to ride 200+ km in a single day.
Halfway there now.

I'm just curious about what my values would be. If they can't be found without maxing out my poor old heart, then so be it. I'll just have to live without that info.
