I'm not sure if this one belongs here or on the Garmin thread so bear with me.
For the past 6-8 weeks I've been running about 2 hours a week (over 2-4 runs) and trying to run at such a pace that my HR stays below my recovery ceiling (in my case 154). I usually have the HR alarm beeping at me quite frequently to tell me slow down. My average pace for these sort of runs is around 14 min/mile (slow I know...)
This morning I went for a 30 minute recovery run the stats from my 305 tell me that I ran with an average HR of 121 and average pace of 13:30 mins/mile. I think the readings that the HR monitor where giving me were wrong. The only reason that I'm not sure about it is that I've changed a couple of other things and wondered whether they are having some sort of impact on my heart rate/endurance/something. Last week I stopped drinking alcohol. My normal weekly intake used to be in excess of 20 units and a day without alcohol would be a very rare thing.
Secondly, I've started introducing a speed session into my weekly milage (in addition to the <70% stuff) and last night did a 50 minute pyramid session (told you I'd start with that one Gobi ;-)).
So, I'm quite skeptical that the reason my heart rate was so low this morning was because of these positive changes that I've made. I think, realistically, it's likely to be dodgy readings from my HR strap. Thoughts anyone?

Does your Garmin log software show any spikes or just a straight line as if it was not working properly?

 didn't realise there was a limit on post length. That should have finished with:
(in addition to the sub 70% runs) and last night did a 50 minute pyramids session (told you I'd start with that one Gobi ;-)).
I'm skeptical that the positive changes that I've made have had such a dramatic impact so quickly and I'm inclined to think that the HR readings I got were dodgy for some reason. Any thoughts?

been trying to import a copy of my Garmin output but I can't for some reason so I'l try to describe it:
It appears to have picked up readings all the time I was out because there definite spikes (4 occasions over 154) but the bulk was between 90 and 130 bpm. definitely looks like it was reading something all the way - there are no flat lines at any point (good job, I might have thought I'd died ;-))

With HR training you do, from time to time, get runs which throw up unexpected numbers. There is something odd that seems to happen where fatigue actually suppresses HR and the day after a harder session you can struggle to get the HR up. There are so many factors that fixating on individual results is fairly meaningless. Overall trends are more important. The stuff you are doing will almost certainly be having some positive effect though

That's interesting what you say about fatigue after hard sessions Chunky. I'll bear that in mind next time.
I've been enjoying the slow sessions because I don't feel wiped out and usually finish thinking I could do it all again but I didn't feel that my pace was improving. Maybe this is a mini breakthrough

What did it feel like? Once you've been training for a while you should be able to feel roughly what HR you're at.
I had a break through today too, much faster for the same HR, able to sustain it over a long run, and able to keep HR lower than usual on inclines. Not sure if it's an effect of training, better technique/cadence or a few faster runs/races. Ot perhaps huts a good day.

Not wanting to rain on your parade susie, but I think there must be at least some problem with the HRM readings - a drop of 10bpm during a run when you don't expect it is possible, but not 30bpm or more. Mine(*) behaves a little like that when it (the HRM strap) needs a new battery - but I generally am getting 9-12 months of running relatively high mileage between battery changes. Perhaps the battery could do with re-seating.
*I assume we're talking about a Garmin here, but perhaps there are other issues with other brands that I'm not aware of....

sounds like you're doing well Meglet
I think that's why doubted the numbers I saw. Some bits were quite hilly and I usually only have to look at one for it to be beeping at me to slow down. this time I was plodding up the hills and still seeing 103 at the top and I certainly felt as if I was working harder to get to the top. I can normally get my heart rate to reach 103 by standing up and walking across the room. I think Chunky's statement about fatigue suppressing the HR might explain it. or maybe it really is a breakthrough. Looking forward to my next run to find out!
