Ha, that sounds like me running, but when I ride it's considerably lower. I love it when my HRM says I'm 28 years old

But since you sound knowledgeable about this... is there any point to zone training when the zones are so narrow? Especially when I'm running. I'm not working at all below 150, and I've never seen higher than 195 - all out, unsustainable, ready to pass out 195. There are supposed to be five zones in there. Does a "zone" 9 bpm wide have any relation to reality whatsoever?
