Hi ,
It looks like you're using an ad blocker.



The revenue generated from the adverts on the site is a critical part of our funding - and it's because of these ads that I can offer the site for free. But using the site for free AND blocking the ads doesn't feel like a great thing to do, which is why this box is so large and inconvenient. Some sites will completely block your access, but I'm not doing that - I'm appealing to your good nature instead. Did you know that you can allow ads for specific sites, whilst still blocking them on others?

Thanks,
Ian Williams aka Fetch

How do you log an ECG from a chest strap?

It has to be a Polar H10, which can transmit ECG over a Bluetooth channel at 130Hz; there are phone apps that will log it. Other chest straps don't, just use the ECG internally for R wave timing.

Very different distribution from the H10, over 80% zeros.

As Badger says, you need a Polar H10. What I use with it, somewhat surprisingly, is the Polar Equine app, an app for tracking the heart rate of horses! It gives a nice clear ECG. Having said that, a year or so ago it somehow gave a false alarm, an abnormal wave pattern, which resulted in a rushed trip to A and E, as I had a heart attack in 2023 and continued to be very twitchy about heart issues. They did a 'proper' ECH there and found there was no problem. So since then I have treated it as something of interest rather than 100% medical validity.

Does anyone else have reservations about proving increased fitness? All my metrics for heart rate on similar runs suggest I should be able to run pretty quickly at the moment but for some reason I'm pretty reluctant to put that to the test.
I've been listening to a lot of people who train a lot at their LT1 threshold.
I've never been measured for lactate but I'm pretty certain that for me this is around 131 bpm (my max is high 160s - If I were to guess a number it would be 167).

So my runs lately have been a mixture of *Easy/recovery - sub 110bpm
*Steady - around the 131bpm mark
*parkrun - mid/high 140s average (maybe ending low 150s)
*a weekly block of short intervals.

*longer runs (either easy or sometimes ending as steady).

What I've not done is really let my HR go much over 150bpm. It should be there if I need it, but I'm worried that if I go there I'll end up sacking it off when it gets harder.

Do I throw caution to the wind and try to prove myself in a 10k or maybe just a full beans parkrun, or keep doing what is showing HR benefits and enjoy that training seems to be working.

I've not got a marathon booked in, but it's definitely something I'm thinking of, and Boston (Lincs) would be the place I'd go if I decided to run one. I ran 2:52 last year and I'm pretty sure I'm in better shape now than I was this time last year and dipping under the 2:50 before I turn 50 (October) definitely appeals.

I mostly trusted the training paces and efforts when training, but still wanted to test myself in occasional races. The odd race effort parkrun or 10k won't interrupt your training too much, surely?

I reread you post which means I edited my initial reply hopefully my re-read means I picked up what you meant correctly.

I think racing to see where you are is fine. If you don't think you should be racing yet though, then stick with what you're doing. There's also the fact that racing can help with fitness but that's why I like XC for the winter as I get the effort without the 'I was 5 seconds a mile slower than I'd like to be' issues that can creep in during the summer season. In addition, as they are usually monthly you get time to train and progress for each one. My 5th metatarsal avulsion fracture means I'm avoiding XC this year and I did my first indoor track race this year to get the racing benefit. Can't avoid comparison with track but still felt the benefit of the racing the week after the race.

Thanks both, I think I’ve got a bit of a mental block that’s come on after a couple of bad races.

That 10k pain you need to go to if you’re wanting to have a good time has got the better of me too often.

Another thing that might be playing into it is that I don’t work on Fridays so I can get a decent longer run in then, so park runs have been a bit fatigued and I’m probably using that as an excuse not to go to the well.

I’ve never ran cross country SPR (even when I was a member of a club), but that might be a good option for a Sunday race effort.

I’ll probably shuffle my week around a bit and give either a parkrun or a 10k a blast in the next month. I do need to try that harder race effort again, and the longer I put it off the harder it might be to do.

Everything you need to know about training with a heart rate monitor. Remember the motto "I can maintain a fast pace over the race distance because I am an Endurance God". Mind the trap door....

A quote:

"The area between the top of the aerobic threshold and anaerobic threshold is somewhat of a no mans land of fitness. It is a mix of aerobic and anaerobic states. For the amount of effort the athlete puts forth, not a whole lot of fitness is produced. It does not train the aerobic or anaerobic energy system to a high degree. This area does have its place in training; it is just not in base season. Unfortunately this area is where I find a lot of athletes spending the majority of their seasons, which retards aerobic development. The athletes heart rate shoots up to this zone with little power or speed being produced when it gets there." Matt Russ, US International Coach
