tjodit, have you joined over at www.bikejournal.com? You can see the mileage for the members and the organized rides they are planning on riding. This may give you a way to understand why some people are riding suge huge miles. I love to mtbike also, so my miles are never going to be huge like someone riding double centuries. My hours on the bike might be sizeable, but not the miles. You have to set your own goals and work to achieve those. Total mileage is secondary to that.

Basic membership at www.bikejournal.com is free but there are great advantages to premiuer membership. You can join the Team Estrogen team and contribute to its miles.

Most of all, have fun.
