£11.45 when I bought it in Dec 16. Now at £21! There's inflation for you.
Good strap though and I've finally got rid of the raw wounds on my sternum by attaching a strip of insulating tape to the top and bottom of the strap.

I've read before that HR may be lower when you are underfueled. Could this mean that you can get a better pace for a given HR, or does it mean you won't be able to push the pace/HR up as aren't sufficiently fuelled for your effort?

The reason I'm asking is that on Sunday I had a 5 mile run around a lumpy local park and despite feeling good I was a little shocked at the pace I was getting for relatively low HRs.
I've just got back from a fortnight in Spain (tough running there in the heat) and just went out for a nice leg stretch and it felt great!

Here's my run

fetcheveryone.com/t-14057206

I'm struggling a little to think that I can have this sort of pace when during my marathon that is coming up (York on 8 Oct) I am hoping to have a good few bpm more to play with.

For a little context:
My max is 165.
My lactate threshold is around 145-148.

My plan for the marathon is to run it by pace (tbd nearer the time but somewhere iro 6:30-6:50 per mile - main target is to break 3hr), but keeping an eye on HR.

Broadly speaking I'd hope to keep HR around these sort of parameters:
135-140 for the first 10 miles.
Slight drift expected but under 145 for next 10 miles.
Prob 140-155 last 6.2 miles (or whatever I have left to get me over the line as quickly as possible)

Any thoughts/comments?

You are fit, you are relaxed, you've been used to running somewhere much warmer and you ran a good bit further last month.

Maybe you should have another week away before the marathon :-).

Sounds like a good plan Dvorak, not sure the missus will buy it as a reason for a holiday though 😀

Brunski, if you leave any spare heartbeats out on the course in York I'll pick them up for you as I follow you round noticeably more slowly!

Haha MarkyMark it's a deal.

I don't intend to leave anything behind in York, but at the same time I'm very conscious of setting off too ambitiously and walking the last few miles.

I've read that the HR average for a marathon is around 87-89% of max, just out for of interest is there anyone who tracks HR that wouldn't mind sharing their %ages from marathons?

I'd have more data myself but (as I've shared on here) my HRM I used before wasn't reliable but seems to show general rising between 140-155 bpm (ignoring the spikes where the optical hrm seems to have picked up cadence) throughout the race.

:-o I think that is 87-89% ave for a half marathon? Marathon around 5-7% lower?

Not that there aren't a few people might do that (and HM at around 91-92%) but they are exceptions.

Dvorak, I must admit that most of my 'knowledge' comes from a pretty old thread on let's run.com.

letsrun.com

Interesting thread for the heart rate geeks amongst us, but be very interested to get a but of a sense check from those on this thread.

I looked back for something about that (I'm sure there has been on the thread) and whilst I didn't find it I did find this: fetcheveryone.com/forum__3882__1828__heart_rate

Two things: Tipsku's posts make very interesting reading and ...

I realised I had not quite understood what you had posted. I always think of the percentages in terms of working heart rate, so that's the averages which I quoted. However, you meant averages of max heart rate, in which case your percentages are probably correct. Apologies.

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
