I am a 14 stone 41 year old male. I run approx 2 times per week for about 45 - 60 mins per run, ride 1 time per week for about 1 - 1.5 hrs. I also play football 1 or 2 times per week.
Should the HR zone percentages change for base training on the run and on the bike. When I run I find that even on a long (ish) run of 60 mins, my HR is generally around 87% - 90% of my HR max. When the road goes up hill it goes above 90%, upto 95%, and when the road goes downhill it drops to about 82%.
My max Hr is based on the POLAR own zone calculation from the fitness test mode of my S210 HR monitor. (I have got within 1 beat of this on a long steep climb on the bike, so I think it might be accurate).
I don't run particularly fast, about 9min mile pace, but the HR rate does not seem to change much if I go down to 9:30. At the moment I am trying to put some miles in at steady pace, but never get close to lower HRs for aerobic runs or recovery runs. On the bike or turbo I can ride steadily at 70 - 75% comfortably. Am I getting the same benefit from my training runs, or do I need to run even slower. I know I can run 5 miles at sub 8 mins as I did at the start of the Great North Run last year (not over quick but faster than training runs) and single miles in sub 7 mins. So why can't I get my HR down on training runs at fairly moderate speeds?
Bit of a long winded post, but I hope someone can make sense of this.
