How many calories an hour does a person burn if they are walking at a speed of 4mph?
...I'm sure there is a site somewhere for this but I was hoping someone just knew it.

In case anyone is interested in other calorie burns also, here is a Website.

Depends on weight, but somewhere between 275 (~120lbs) and 475 (~200lbs) calories per hour.

Sherasi-
Thanks for the site on calorie burns. Gives me a better idea on what/how I'm doing.

Thanks guys! Looks like walking really is a good thing for me to keep up. Now, if only the weather would warm up for good...
