bikeriding or walking (question)

[Guest guest]

Hello everybody in the different groups:

I have a question. How many calories does

bikeriding at a fast-hard speed burns in 60 minutes (one hour)? I just wanna

make sure i am right, because I went so some web sites with calorie

calculators that claim that bikeriding burns between 500-700 in one hour.

Is that true? And how about walking? Which exercise is better to lose

weight walking or bikeriding? Consider that walking burns a lot less about

300-500 per hour.

Please answer me as soon as possible ;-)
