Right, last night I got over the 'running nerd' stigma and wore my HRM to bed. Now it stopped recieving a signal after 2 hours, due to the bedding getting in the way, but I'm pretty sure I hit REM by this point anyway. The lowest HR reached was 35. Now, I'm no expert on HRM's... is this the value I use as my resting HR when calculating my HR reserve? If so, the values I would have to use are:
Max HR: 225 (Not a fault, measured on several occasions! Once when nearly ran over, twice at the end of a race)
Resting HR: 35 (obv.)
HR reserve = 225-35 = 190
Therefore easy run = 158 to 170. This doesn't feel like an easy run!
Wheres the error? Are the 225 (I'm 21 by the way) readings artifacts? The highest I got in my Mile reps yesterday was 185, but thats no a good measure either. Should I use 200 as my max value?
Brain hurt. Must stop thinking!
