it is not based on speed.

The main factors used to determine calorie burn are your weight, speed and activity type.

But, is it possible that in a 75min ran at a low speed of 22km/h (cycling) and in a flat terrain I can burn more than 1000 calories?

measurement is done by global average.

for instance, walking 5km/h for 30minutes with 75kg of bodyweight averages a certain number.

look for METS for specific numbers in relation to kcal

it all comes back to; labour=times *distance
this calculation does not incorporate height gain or loss!

Actually, one thing that can be used to get a very good estimate of calories burned (< 5% error) is the heart rate.

It's really important to me to understand the calories figures on SP since my first exercise goal is weight reduction. Im 91 KG now (reduced 8 KG in the past 6 weeks with dieting and regular intense cycling).


I have 2 examples to compare: Ride A is all on local small roads in mountain area. I'm most of the time climbing and obviously when it descends I go full steam down.. Ride B is longer but flat all the way. I dont push my heart so much as on ride A and try to keep a more regular speed. Now here comes the question and the help: Ride A makes me noticeably more tired and definitely need more effort to accomplish it. However the calorie counter is lower than on Ride B. How we explain this and what's the way to solve this? I'd love to have a heart rate monitor function supported by the app. Is this the only way to improve the calorie function? What about inclinations?

Steep climbs and descends, 31 km ride,1hr 44 min: 1138 calories

Flat terrain on a bycicle path, 38 km ride, 1hr 52 min: 1400 calories


Thanks for the comments!

That's my point Itay.. the method for counting calories is too simplistic and I really need (prefer/would like) to count them more accurately since im on weight losing mode..

Anyone has experience with the garmin forerunner 405? includes a heart rate monitor.. but i was not convinces since it's supposed to be designed for runners rather than bikers.

of course i'd love to have a wireless heart rate monitor paired with my phone and the sporty pal aplpication running but so far is science fiction.


Thanks for the comments, Alan

I wouldn't start adding the climb/decent values in to the calculation either as they're a little off - most of my routes are loops starting and ending at my home yet sometimes I've climbed over a hundred foot more than I've descended - trust me, my house ain't moved that much in a couple of hours ;)

As mentioned if you're that keen on counting calories burnt you really need a heart monitor - SP does its best to give you an indication but no matter how complex you make the calculation it's never going to be spot on for everyone in all conditions.

My main focus of cycling is to lose weight too - shifted a stone and half in five weeks thanks to a few miles cycling and cutting down on snacks but I take the calories burnt with a pinch of salt - the routes I do I will re-do if I feel like they were a good work out and tested me - more often than not though I'll do a different route just to keep the scenery interesting.

Like today, took the train out for a thirty mile jaunt home - few wrong turns made that forty three, unfortunately I can't show you as SP crashed on me - first time it's done it mid-ride for me but a tad annoying it was on a "biggy".
