Dom I`ve never really cracked racing with a HR monitor. HR drift complicates things. Perhaps I should give it a go.
I just try to cap my HR at 165 from the outset. I know I can maintain this intensity for 26 mi. If my HR starts to head up to 170 in the 1st 20 miles then I`m buggered.
I've used the HR monitor in the past in the marathon to help me conserve energy. My maximum is in the mid 180s and I've had it up to mid 170s when I'm doing the dreaded track session with the club, but in the marathon I tend to start in the mid late 140s and expect it to gradually rise to the mid 160s by the end of the race.
165 is my half marathon HR and I generally go at that from the beginning and try to hold on, I don't do that in the marathon though- no way. To get the very best marathon performance out of myself , one day i'll have to gamble and try to run close to the edge without knackering myself too early. I think one has to know the body really well, and it comes with experience of running the distance.
Jimbo76 it definitely helped my last block of training. I tried to ease off the pace on quite a few of my sessions to conserve energy for other sessions. This helped me to build up the mileage and be more up for more long runs. Sometimes I would feel like maybe I'm running too slow, but then I'd look at the HR and see that I am keeping it under control. Other times I would try to hit certain HRs for different workouts. It became less about "mins per mile" and more about "type of effort". On the whole my sessions were probably slower that last year's (Spring Campaign) but my results from this year's campaign were a half marathon PB and marathon PB that were very near the top of my hopes and expectations.
