Hi,

Is there an online calculator for this? Anyway, I just started cycling to supplement my running and I want to know how intense it is and if I am working hard enough. Today was my fourth day.

Can somebody give me a calorie estimate based on:

125 pounds
Trek 7200fx hybrid bike
relatively flat with 5 small hills, road surface
18 miles in 1 hour 10 minutes

How many calories? Also, how many calories would it be if I do 12 miles at same pace on the same surface?( I'm alternating every other day)

Thanks !

There are many more variables that determine this. I punched what you gave us into an online calculator and came up with 510 calories burned. If you ride the 12 mile loop you will burn 340 calories. Without knowing other variables like wind speed, etc., it's only a rough estimate.

A very, very very rough estimate.

Does it matter what kind of bike you're riding?

Yes, friction from the bike, from the ground and from the air.

A good calorie counter website, more detailed than any I've seen previously.

Looks to be quite hight.... no way I burn 953 calories avg. 16-19 mph in one hour. S/B 600-700 cal.

I have a stationary fancy bike which simulates biking. It tells me approximately 700 calories per hour at 18 miles per hour at 90 RPM for 195 lb. guy assuming no wind.

www.Kreuzotter agrees with that.
www.caloriesperhour comes up with 1100 calories per hour.

Calorie intake for (4) x 10 hour tour is based on 700 calories per hour. We would develop problems if the 1100 would be correct. With 7000 calory/day intake we had no weight loss.

Making a few assumptions, my CycliStats (http://www.cyclistats.com) program indicates that you would burn 627 calories on your 18 mile ride. Assuming similar conditions, your 12 mile ride would burn around 418 calories.

How in the hell are you going to ride a bike with no wind? Wind resistance is one of the most important parameters in cycling, along with body weight and distance.

Roody:
Not an exact science I will admit.
A circular track somewhat makes it wind neutral I think.
Going east to west and reverse does that too, approximately, I think. Assuming steady light wind.
A Watts meter lets you get an average and that can be simulated with drag on a stationary machine.
Close enough for my purposes.

Roody:
Did you read the definition of the www.Kreutzotter.de calculator?
It is quite sophisticated and does calculate wind resistance. Of course the added wind needs to be factored in but you can also assume side wind.
I checked it again and seems to be accurate within 10%.
