Can anyone offer some advice on judging half-marathon pacing by monitoring heart rate?
I'm running in the Fleet Half (20/03/05) as prep for FLM and for once have been pacing myself sensibly by using a heart-rate monitor. I'd like this to continue but would also like to score some PBs, mainly to build confidence.
What I'd like to know is what is the ideal/ accepted heart rate, either in terms of working heart rate or maximum heart rate, that is 'most efficient' for racing a half? eg is it 80% of WHR, 90% WHR, less, more...aaarrrgh!
