Mine's a Garmin 405 - maybe it's a bit more primitive?

I've said it before on here, but I'll say it again, for newer readers...I used to get the problem quite often with the HR reading something excessively high like 175-180 for the first mile. It's caused by static and the figure is actually your running cadence. However, I don't think I've had it once since I got into the habit of running the strap briefly under a tap before putting it on.

Saliva on the strap work for me, slightly minging I know but gives a good connection with my chest 😀

It's not my running cadence. Mine guess all over the shop from 230+ to low 80s. Neither of which is cadence.
I agree that it is likely to be static though.

I should perhaps have said it's my, rather than your, running cadence, as that's what it is with me.

My original Garmin strap always had similar issues in the first mile plus the fabric edges chafed and had to be taped. It has 3750 miles on it and the rubber is perished. I've replaced it with a Garmin Premier strap (£34.99) which has rubberised edges and doesn't chafe. It has 5 or 6 runs on it and HR comes up smoothly on each one. Early days but very pleased so far.

Just out of interest, has anyone noticed differences between various training logs re the average heart rate on runs. My FE log has my average for this morning's gentle run at 125, Garmin has it at 126 and strava at 127!!

Just looking at your log on here, and on strava (tracked you down and followed you!), the whole run was a bit stop-start wasn't it? strava shows moving time of about 27 minutes, running time about 22 minutes. I think strava / Fetch / Garmin all deal with pauses in subtly different ways, which would probably explain that.

There's been some discussion about heart rate variability (HRV) on here recently. I just thought I'd report back on a couple of interesting findings. A few weeks ago I started taking regular HRV readings again, as I had done about 18 months ago, this time though using Elite HRV, which seems to me to produce more consistent and reliable readings than what I was using before.
I've observed before how when you're feeling run down or tired, your HRV tends to go down and when you're feeling refreshed it goes up. But this doesn't really help you much if it just gives you a number to assign to what you already know, can already feel. A couple of times in the last week, though, the HRV has been rather more interesting. One day I took my reading in the morning, feeling tired and badly slept and expecting a reading at the lower end of the scale. To my surprise, the HRV came in at the higher end of the scale, with the accompanying message "Compared to your recent baseline, you should be able to train harder and handle more stress today". Sure enough, when I went out for a run later on, it all felt surprisingly easy - perceived effort suggested a pace probably 15 seconds per mile or so slower than what I was actually running.
Then a couple of days ago, the converse happened. In the morning I was feeling reasonably fresh and expected a high-ish HRV reading, and was surprised when it came out really low. Then when I went for a run later on, it all felt rather more of an effort than it should have done. I kept
So HRV seems to be tracking something about my preparedness which I can't necessarily feel - and that is very interesting and potentially useful. I'm using HRV to inform my training now, one day shelving plans for a tough efforts session if my HRV is lower than expected, and another day working a bit harder if the HRV is higher than expected. Ultimately it's only ever going to be fine-tuning, because I take a common sense approach to training anyway and almost never run back-to-back hard days. It's early days yet but I'm intrigued to see where this all ends up.

Thanks for that. The treatment of the "stop-starts" would explain it. My easy early morning ones are with my 4 year old Border Collie and there are quite a few stop/starts - the main one being when I have to wait for him/pick up his morning deposit!
