And it isn't the 5k I mentioned. Posted in a hurry and didn't think it through.

I use an old Polar T31.Basic. Chest strap. Until recently it had been consistent over a period of four years and pulse shown on screen and average pulse seemed to fit perfectly to my pace/how I was feeling. The sudden spikes I have had recently and foolishly only just recalled, might be down to the fact that I had to tamper quite a bit with the body of the watch in changing the battteries, after which it took an age to start reading at all! And of course sudden spikes occasionally happened when I ran in certain places--again consistently! Forty years ago I used to stop after a mile and count my pulse against the sweep hand of my wind up watch. And did it periodically and at the end of a run. It was a good enough indication at the time (excuse the pun!) of whether I was pushing myself or not. |

I'll maybe post a pic of mine. Mine is actually as your words described and like your picture (even though your two don't match up Badger!) I run a consistent effort or possibly gradually rising effort. I get HR showing steady or slightly rising 150s-160s, then a big jump to 170s-180s. The big jump is probably as Larkim described, a change in the algorithm the software is using to interpret the input it is getting. But it means what it is giving me is rubbish. I'll try and post a pic later. On "chat" to Garmin Support now... I'll keep you posted!  G

Hi all I am looking for a HR Master to help me with a plan.... I have 'ran' for a number of years now, but I kind of just go and run without any structure and I am thinking I really need a proper training plan - you know the intervals, hills, long slow runs, shorter faster runs. But what I also think I need to do is start with some proper foundation stuff and get HR training and build from there. My ultimate aim is to overall get some pace back but also the stamina to do the long stuff having signed up for another couple of marathons next year (March and May) I broke my foot in March this year, took 10 weeks off and since have been building back up but I'm slow, my legs feel like dead weights and its all knocking my confidence.... What I am after is some thoughts on whether this is the right thing to do, and if so where the heck do I start to do it properly? any help will be gratefully received. Thanks |

Don't match up, HG? For the most part they're within a few bpm, bar a couple of spikes, and they match pretty closely even in the jump at half way. The left scale is for the difference, the right for both the HR traces. Let me be clear; my point is that, for heart rate (not HRV), the problem is not the optical technology itself, it's the way it's implemented in the back of a watch. Wrong part of the arm for good signal, too badly affected by arm swing. I agree with you that watch HR is rubbish for hard runs, but then I said that a couple of pages back. |

Garmin Support said "... try a hard reset..." The equivalent of PC support telling you to switch it off and on again. Sigh. Oh well, will try. Badger, I meant that your words (a hard 5km) didn't match the picture that you posted (the HR graph(s) ) I think that's what you said, wasn't it? I do think the optical HR technology is fundamentally flawed, or limited. And that if it works occasionally for some people, they are lucky, at best! As you say, top of wrist isn't great for either blood pumping or for arm swing effects! What they need to invent is a waterproof, hygienic, long term, chest sited (or whatever location is best) HR sensor. e.g. a paper thin, stick on sheet or strip, wash and shower proof, that would not rub or come off or get dirty. Reapply once a year or something. G

Sorry, that was "wrist based, optical HR... is fundamentally flawed..."

Sadly have to agree with you G. Also more worryingly the Vivoactive 3 is consistently long when measuring miles (so my races are now always coming up short) and against the old Vivoactive. I'd read it's altimeter measuring was more accurate, but if you look at a run earlier this week it shows a 100m difference in altitude between the same space of road run on an out and back course. And then I read on Garmin forums: reddit.com So a more expensive watch (presumably because of optical HRM), doesn't actually measure HRM properly or mileage or altitude. This will presumably feed in to its VO2 Max calculations and its stress testing (based on HRV) as well. |

GG - if you are going to use heart rate to build a base then the first thing you need to do is calculate some ZONES approaches - GUESS(226- age) , not great really and people like me at 48 with a max of 187 make a mockery of this approach run a hard 5km and really go for the line, you should pretty much max out your HR, will be better than above hill reps x 3 - run hard for a minute up a hill all in death and honour after 60 seconds jog straight back down taking no longer than 2 mins , turn and go again. etc. If you notice that your heart rate at the top of rep 3 is higher than rep 2 turn and go back down doing a 4th rep. Back in the day we used to do 5 reps but lots of analysis said most people get the best effort out in REP 2 a few in rep 3 as the effort is so hard you go bang and although you try hard you just cant push as hard in the later efforts. This gives you the max , over a period of a fews days (same time each day) take your resting heart rate. From these numbers use the Karvonnen approach to set your zones. To build base spend a month below 75%, vary it though so work out all the zones in 5% chunks and mix the days So sub 60% (will feel very slow) sub 65 sub 70 sub 75 sub 70 sub 65 sub 60 etc..... This will build a good endurance base All the best Gobi |

With you, HG, agree entirely!
