Fascinating listening to Steve Way on the latest Marathon Talk episode talk about how he only had the heart rate fiend on his watch & how he was pretty much a slave to it throughout the race. It certainly worked for him & it's certainly something I'm going to consider for this years Snowdonia marathon!

Should have typed field (although on 2nd thoughts, for some...!?)

I've often considered the idea of doing something similar in a race, but not yet dared so far! That is, aim for a certain heart rate (something I know will give me a good time in a race), and not drop below it or go above it. There's the idea that if you're only running at, say, 90% of your HRmax and could be running at 94% (like in a 5K), you could push up the HR until you're running at the target rate, because you know your body is capable of it (from am HR graph from a PB race, for example).
Having said that, though, I've definitely come across 'central governor' issues, where because of tiredness or whatever, I have not been able to attain my normal heart rate for a race (my central governor brain is presumably protecting me). So there are issues with using heart rate.

John Kynaston is a very successful Ultra runner and he is absolutely obsessed with keeping HR below a certain figure, I think it is 130 but could be 135 bpm.

I have done this, for my half marathon PB. Stuck to 145 bpm for the first ten miles.

Especially at St. Neots, where the last three miles are downhill.

And then you sped up and dropped to 140?

The trouble with racing to HR is that you'd have to account for heart rate drift. Your heart rate for the same pace and effort level will always rise due to core temperature rises, particularly after, say, 12 miles. If you adjusted your heart rate you'd end up slowing down unnecessarily and under performing

I'm not a marathoner, so can only quote Parker's suggestion, for those unsure of their training level, of keeping WHR below 75% for the first 20 miles. Taking your points on board SSLHP, this probably means letting it gradually drift up to that level, reaching it at 20 miles. After that you should be in good shape, so go for it.
