Long run done, 22.25 miles. 3 hours 15 minutes with 1085 ft elevation gain so how the hell is it fair that I have only burned off 1850 calories.

For people who know about this stuff, I was wearing a heart rate monitor as I am told the data is more accurate with this. I am also 12 stone and medium build.

I just know I am going to spend the next two days hoovering all the scraps of food up in the house.

It's neither fair nor unfair. It's just the way it is, so suck it up.

What kinds of food are you refuelling this? That can make all the difference.
20/02/2012 at 15:06
@Keyboard - that sounds roughly right for me.... it all depends on your pace as well. Just enjoy and make sure that you're refuelling well

If you are 12 stone and you ran 22.5 miles then you will have used more than 1850 calories.

Basic approx. is 0.75 x weight in pounds for a mile. So 126 calories per mile roughly.

Being 13 and half stone I burn even more calories. Unfortunately I can consume them at even more impressive rate!

How do these heart rate monitors calculate calories?

Yesterday I ran  20.8 miles, in 2 hrs 51, and burned 2533 calories apparently. I weigh 11stone. I used Garmin 303 without using heart rate monitor.

I ate a lot yesterday after that!

I don't really know how wearing the heart rate monitor affects the calculations, I just know that the calories burned are always much less when I wear the heart rate monitor than when I do not.

Perhaps it works out how hard the heart is beating so can guage relative effort?

It is the same with me I only 'burn' half the calories per mile when I wear my heart rate monitor even when it's up in the mid 170's which must be getting towards max for me at 45yrs old! Not sure what my max is though but waking pulse is around 50 so there's a big difference surely it must take loads and loads of calories to beat that fast!

KW - computer says 2832 calories...

I just estimate about 100 calories per mile - you wont be far out, and I dont think theres any way you can do it precisely. Gym equipment is notoriously over hopeful in their estimations. Strange eh ?
20/02/2012 at 20:36
I'm not too precise about it really, I just think for that monumental effort (for me) I should be able to eat chocolate and ice cream for a week and still lose weight!

On a related note. Whoever came up with the 2000 calories a day was also having a laugh. If I ate 2000 calories every day I am certain I would put on weight. Who says we should be eating that much?
20/02/2012 at 20:43
Quite easy to eat 2000 calories a day. You seen the calorie count for meals in McDonalds?!
20/02/2012 at 22:53
Should be nearer 2500 calories I'd say.
20/02/2012 at 23:08
2500 cals a day is quite rediculous really, I run 70 odd mile a week (really hilly) and dont eat 2000cals but my weight barely drops below 11st so am pretty sure that "expert advice" is utter claptrap.

3 meals

3 snacks

Very little alcohol

Ready meals to a minimum.

Never eat the low fat , low sugar, low salt option, as they often are full of other crap to create taste

Just eat less of the full fat.

The majority of evening meals must be made from scatch.

Missing breakfast is punch in the face stupid

Toasted pitta bread and hummus after a run is wonderful.

Prunes

Porridge

No runner should even know where to get coco pops.

Pie and chips at least once every 2 weeks.

MacDonalds is just weird.

...and on and on and on......

Oh and lots and lots of tea.

None of that coffee

Foreign muck.

21/02/2012 at 07:06
Ah yes I often pass those English Tea fields on my long runs
21/02/2012 at 12:14
lol
21/02/2012 at 12:21
If you're near Truro you can actually run past a tea plantation ... tis true!
21/02/2012 at 12:36
Mutteley you are a legend.

I'm getting some of that tea.

May all your runs be swift.

Those sports drinks they have at races are dire, I would
support who ever had a tea and cake tent at a race.
Chelsea buns, Victoria sponge, Bakewell tarts.
Those give you energy!

I agree with Cougie. In Ranolph Fiennes training book which is supported by his expedition partner Dr Mike stroud who is a very respected nutritionist, he explains that a good guide is 100 calories per mile but that depends on how much effort you put it. He basis that on approx. running at 6mph or the same if you were doing approx. 15mph cycling and it is a good average for a variety of forms of exercise. Obviously the intensity and your body weight will cause slight variations. You must also consider that your device will not be a hundred percent accurate so you may have burnt a bit more calories.

Based on a 100 calories per mile you would roughly expect to burn 2200 for 22 miles so you are not that far off really. Maybe your intensity was high. They also explain that if you run to hard you will burn energy that is stored in your muscles through recently eaten food, which builds muscle and doesn't burn fat as effectively as lower intensity training. By going at lower intensity, you burn fat instead which is what allows you to run for longer and with less likelihood of hitting the wall as you are using your fat for fuel, which will carry you a lot father than using your energy stored in your muscles.

So if you are running to burn fat then try lower intensity/slower running. People often think they must max out or train at 80% of their maximum heart rate but the most effective fat burning range and good endurance training range is 60 to 70 percent (which in a 25 year old would be 117 to 137 beats per minute) of your maximum heart rate. Hopefully that way you may burn more calories for every mile you complete. For maximum heart rate and the training zones here is a link to a helpful graph:

Hope this helps
