I've just come back from running the Plymouth half marathon and for the first time I thought I'd keep a check on my heart rate for the duration of the race.
Imagine my horror to notice that for the full 1 hour 40 mins my heart rate bounced off 195 BPM... it dropped no lover than 188 BPM, is this normal?
I know that on the treadmill during a sprint finish I've had my heart rate as high as 213 BPM which again I find pretty astonishing...
Is there anything I should be worried about?
I'm 31, and reasonably fit (I believe)...
