Clydesdales/Athenas (200+ lb / 91+ kg) - how do i find out calories burned using cyclo computer?

I just got back from a ride. I'm wanting to have a fair estimate of what my calories burned are. The trip was 1.24 miles long and i went a max of 12.4 mph, with an average of about 8mph. The average speed might be a little higher but i'll just say 8 since i'm pretty sure i'm doing that all the time (reset my computer too soon to tell).

thank you

http://www.mapmyride.com/ has a calorie counting function.

Tom, what do you put in the "Power" category?

If you stay at the default setting, it will give you a speed of 14 MPH, so, that could be considered a light to moderate effort.

400 watt output gives you a 25 MPH on flat ground.

Most riders actually average around 250 watt output average with peaks and valleys of 100 and 400 respectively.

Even if you stay at the default setting,though, it will give you a starting baseline. I'll look for something to estimate the wattage output for a cyclist, though.

Default works for me. My bike has never seen anything over 22MPH even going down a bridge. I can't imagine doing 25 MPH on flat ground.

Thanks for the information. You are all-knowing.

I imagine the calories would be higher if you are on a heavy mountain bike compared to a light road bike. Do these calculators take that into account?

This calculator I set allows variables like bike/rider weight, tire type and size, etc.

Play with this one:

That's the one I normally use, but the link had been broken. It's good to see they have it fixed. You can bet I'll be saving it as an HTML document so I can host it on my internal network server for my own use now, in case the link tanks again. ;)

Just don't use the Garmin calculator, it's hideously high

They have some other calculators on the right side of the screen, like this one (http://http://bikecalculator.com/wattsMetric.html) for metric units, or this one (http://bikecalculator.com/wattsUS.html) if you want to use US units.

In these you supply speed, and it provides watts. The difficulty in all of these calculators, is what to do about grade, if I start and end at the same place, then effectively up and down hills match up, but I know that hauling butt up some of the big hills uses way more energy then you gain from going down the same hill. Wind is the same deal, a strong head wind is much more of a hindrance then a strong tail wind.....

When you have a single hill, I've always estimated the average grade by starting elevation vs ending elevation. That way, if nothing else, you underestimate the required output.
