My coach has me training to Heart Rate levels.
My power meter allows me to get to, and maintain, the correct HR accurately.
it takes the guess work out of maintaining a level of effort.
With experience it can be done without a power meter, but not so easily or accurately.
Lastly, a power meter gets you bragging rights. I could see a team of same aged athletes using it to compare teammates performance to their own.
Not a useful or helpful comparison. But me and my 50+yr old friends are guilty of it.
It can be quite disheartening if you’re on the bottom.
PM me if you’d like a coach suggestion.
