That’s some serious zone 5 on a hot day! Nice effort!
I maxed out on the downhill from the reservoir. According to the formulas, a max HR of 181 is much too high for me. But I don't put much stock in those formulas.
Yeah, me neither. That’s about my max, tho! It’s really hard for me to get > 170 these days
Because your heart is super efficient from all that training.
