I just came back from a short-ish run, which I found agonising (because I generally find running unpleasant.

In any case, I Strava told me I averaged 7 km/h for 29 minutes, which (again, according to Strava) means I burnt 406 calories.

Myfitnesspal, on the other hand, tells me it was only worth about 310 calories.

I can handle a bit of a difference, but that’s a 25%. I prefer the Strava number, but want to be realistic. So what’s your scientific opinion? Between the two, which tends to be closer to reality?

Did I burn 400ish or 300ish?

358

200ish

Do both apps know your weight?

Which one was using your HRM?

These tools have no idea how much energy you’ve used up, they are just guessing. The real value varies wildly based on so many things.

All I know is that when I let Strava “guess” calories used during exercise, as opposed to feeding it heart rate as well, it reads much higher than reality.

200ish

Calories or STW pages?

THAT’S the kind of thing I was looking for. I wouldn’t have expected anything accurate; just hoping that I did better on the activity versus intake than I have for the last few days!

You’ll be using up energy afterwards to recover too.

Nice! Sounds like I can have another piece of cake. 8)

Roughly 100kcal per mile is what I use.

Soooo you ran 2.1023 miles-ish, so 200kcal.

Remember, it’s better to underestimate, than overestimate. The latter just makes you molgrips 😉

We seem to do this about once a week…

We seem to do this about once a week…

So I got this week’s allowance.

I will await next week’s with self-satisfaction.

Consider yourself lucky. The older Garmins overestimate by a factor of 2. Newer ones seem much better if they have your proper weight and hrm

But its still only an estimate

Buggerall.

You need to run for at least an hour before you burn anything.

Stored fat stays with you until you run out of that slimy stuff in your muscles, once that’s gone you burn fat.

Build slowly, walk if joints hurt, lay off if sore, back on it once soreness has gone then build until you can run an hour at pace before trying to estimate calorific usage.

See you in a week when your joints give up and you start another thread called “ouch, why..??”

I will await next week’s with self-satisfaction.

I have last week’s copied and ready to paste 🙂

Depends on your objective.
