Starting 'steady' and then winding it up requires discipline (too much for me)...nice one!
SSLP - glad to hear of the improvements, this HR training really works

Over the last year or two I've been wearing a heart rate monitor during races as well as in training. I never actually observe my heart rate while racing, but I find it interesting and potentially useful to analyse the data after the event. One thing I've observed a few times now is how tiredness prior to the race appears to affect my heart rate, and I've particularly noticed that the last 2 Sundays, when I've run slightly disappointing half marathons when feeling really tired (from lack of sleep, rather than physically tired).
Both these HMs were about 2 minutes down on my PB from 18 months ago. For the PB HM I averaged 92% of my HRmax for the race, whereas these recent 2 were 88% and 89% respectively. For all 3 races, though, I would say my perceived effort was the same. I'm wondering whether what's happening is that my brain as central governor is kicking in to limit my heart rate for protection when I'm feeling tired, and doing so rather less when I'm fresh. I know that the ability to sustain a high heart rate throughout a long race is also a sign of overall fitness, but I don't think that's what's going on here as I've observed the same thing when racing tired during a period of proven high fitness (i.e., lowered heart rate when in other races in the same period I can sustain a higher HR).
I have a target time I'd love to achieve before I'm too old (sub-1:20 - the recent 2 were 1.22.x), but to do so I really need to be able to access that upper range of my heart rate. Getting my lousy sleep sorted out would help a lot, I feel.

J2R, interesting post. I think you've a point about running when tired. It features quite heavily in the Hadd threads that I've read that when unable to get to the higher HRs it's often a case of lack of sleep, carbs, etc. to fuel the effort that's lacking.
As I've said (sorry prob too often), that I also struggle to get the HR up and keep it there, my central governor seems to be very strict about taking things easy...I've often thought maybe he knows something I don't, and that I need to listen to him?

Your central governor can be trained too, I think it's hard to defy, but yes listen. HR isn't the only measure, sometimes you can struggle to get it much over 90% I find and other times, keep it banging on happily at 91-92 for miles.
I'm seeing for me what are a record set of low HRs at low speed, and very good HR readings for me at high speed, but I'm not in pb form, and when I have pb'ed in past recently it's been preceded by a very average set of avg HR readings.

Ok same question as I put to polarised training thread, but I think more people follow this one:
here's a killer question - should walking time be counted as part of your training (ie walking for a mile at least kind of thing). If not, why not?
Last December - walking up a hill at average HR was 125.
Today running over a hilly 5 miler at 9.45 pace , my average HR was 129.
Therefore little difference... Big question as it makes a lot of difference to training miles. I walk 2 miles a day with the dog....

I'd change the question, why are you running to HR?
I've noticed the other athletic disciplines I have to work really hard to get my HR to the levels achieved by a relatively easy jog.
What is the training effect of walking?

Obviously you can log walking as cross training if you want. There's also nothing wrong with run-walk, although I advise keeping the walk breaks short so the HR doesn't drop too much.
Otherwise I would say it's a question of intensity - is HR above (say) 100bpm?

Answer - so I know my easy runs are easy. I have noticed that by doing one hard session and one tempo and the rest is easy, my heart rate drops dramatically for the same speed and consistently each fortnight (it will bottom out I expect). This didn't happen when I was doing 100% easy. My ratios change if I include walking from say 20-80 to 10-90

I've been considering asking that very same question, Chrisull. In fact I started a thread a while back here, 'Brisk Walking Benefits' (http://www.fetcheveryone.com/viewtopic.php?id=59693). I often push my HR up pretty high for walking, certainly into the slow jogging range (100-120), and occasionally much higher (I've managed to get to over 160 at the top of a slope taken at a fair lick).
So in aerobic terms, I reckon it's all grist to the mill. My concern would be that the physical action is sufficiently different from running for it to be considered more as cross-training than as running training per se. I don't count it in to my weekly running mileage as a result, although I'm sure it's beneficial. Mind you, the walking I'm talking about is pretty fast, 12:30-13:30 pace, nothing like strolling.
