I believe the max. bpm heart rate is 220 minus age, for myself as 65 years of age this works out 155 max bpm. Recently I've reached 160/170 bpm while using a treadmill going by my personal HRM and the treadmill heart rate monitor, both gave almost the same reading. Is this safe and maybe normal ? I've always believed that when training for the threshold rate bpm should be approx 85%, approx 125/130 for myself. I have been running for over 30 years so don't think of myself as a beginner by an means.
Jeff, if your max is 160bpm then your 85% would be 136bpm.
As cougie says do a max test , you'll know for sure then.
As for threshold rate it might be a lot lower/higher than you think, but i would not guess it, try reading through the HADD thread lots of intresting info going on there.
