I am now a yearling cyclist. I started riding in the spring last year but only rode about once a week for 10-12 miles. This year I've decided to switch my major form of physical activity from running to cycling, so I'm trying to get somewhat serious about it. For various and sundry reasons I've JUST started riding this season and am LOVING it.

I'm also hoping to drop a few pounds over the summer. I would really love to have some idea of how many calories I burn when cycling. I've looked at various websites and have seen huge differences in the numbers they quote. I understand there are a lot of variables that make it impossible to know what a particular rider on a particular bike on a particular terrain might burn. But I'd love to at least get in the ballpark. The biggest question I have about this is what difference riding on hills makes. I live in very hilly country and can't help but think (hope!!) that I burn more calories than I would if I lived in the flatlands. Can anyone give me any insight into this topic?
