High heart rate but feel fine...
I used to run a lot 5-10 years ago in my early to mid 40s and recently got back into it at 51.
My concern is when I run my heart rate gets pretty high even tho I feel fine. My max hr should be 169 according to my age.
I start out at 5.8mph and at 7 mins I am @ 168bpm, 12 mins @ 170bpm and then it stayed there (up to 172bpm) until I hit 22mins at which I go back to a fast walk.
However, at 22 mins I still feel fine and feel like I could go on much longer but the high HR freaks me out.
At 43 years old I was running 6mph for 1 hour.
Should I trust my body or my heartrate?
Thanks.
