I had a weird experience where my HR is no longer my redline gauge I've been on a spurt of getting in miles, long miles in on the roadie since I can't ride my MTB yet (ankle sprain last month). In return I've also nearly double my ride time since I don't have to drive to the trails anymore.
Last night after work I wanted to do some hills before the sunset, I did a 70mile ride sunday, recovery/rest day monday so thought I would be good for a "hammer" ride. I have a hill not to far from my house that I was on a mission to PR or blow up my heart rate trying. My max HR is 190, normally won't see anything over 184 unless I'm about to pop.
It's about 40mins til I get to the turn off at the base of the hill, So I hit the hill in big ring then shift down to hold leg speed up. My HR is only 153..WTF...ok 10% grade right hand switch and I gun it some more...158...WTF and my legs were getting tired & not limited by my heart rate being sky high. About 200yrd later it turns to only 4% grade so throw it back in the big ring and try to stay around 13mph through the power rollers. My HR was still 162 at this point then calmed down too 144 but legs were getting torn up. So I just try to keep it at the limit of my legs not my HR which is a very weird first for me....at least in a long time.
Here's the hill, previous PR was 15:42 , new PR is 14.40 w/ ave HR at 159
I then PR'd the next climb @ 13:46 vs 15:22

Is my conditioning getting better or am I just riding too much and wearing myself out? MTD is 330 miles so far.
