Seriously? All we're talking about here is pulse, right? If watches can't do that, why are they getting away with claiming that they can?!Chest is the only accurate way to measure HR really.
Well, I took it pretty seriously in my youth (over 35 years and a sub 1:10 half-marathon ago) and that was with just a Casio or Timex on my wrist, a 3.5 inch to a mile map (at home!), some thread and a ruler to calculate the distance and a calculator (Casio again!) that did degrees so you could calculate hours and minutes per mile directly - it seemed that I had everything!Running with a phone is infuriating, and whilst an Apple Watch is a great all-rounder (I wear one every day), they lack the specific functions if you end up taking running seriously
I look at it and cut it in half to get an accurate reading and that's with a Garmin 820. It shows me burning around 40 calories a km, which I think is ludicruous. (Probably because I refuse to wear a heart monitor). I work on the basis of 50km gets me a bottle of wine. But I'm carrying 83kg so I will burn more.Just jumping onto the back of this thread, I've been doing a bit of cycling recently - mostly in an effort to improve general fitness, core strength and perhaps shed a few pounds.
I use Strava running on an iPhone attached to the bike, which seems to do a decent job, but I'd be very curious to know more about how many calories I'm really burning (I know that the answer is always "not as many as you think"). I'm told that Strava will massively over-estimate this unless you have a HRM.
I don't want to get into power meters built into cranks or anything like that, but if I could spend < £100 to get a more accurate idea of calorie consumption, that would be fun.
Any suggestions? Maybe a wrist-mounted HRM that talks Bluetooth to the iPhone? I'd rather avoid something around my chest.
Yes the Strava specials have gifted me a couple of world records too...The only thing that I find (mildly) infuriating about my phone (with Strava) is when once in 100 runs it loses the signal and you suddenly find you've run faster than world-record pace for a mile and a straight line appears on your strava course map - I delete those because people will just think I used a bike to attain a ridiculously fast time - as I assume with others' personal bests under 3:30 per mile ;-)
