Standing is fun - at least I like it - but, I agree, probably is not the best idea. I've noticed several times that I'll be sitting while climbing and another rider will stand to climb. I've noticed that I stick with him up the hill and I imagine that I've expended less energy by sitting. However, there are other riders that stand and can then leave me in the dust. So I guess it has it's place - especially for those that are strong and light and can recover quickly. I'd like to be able to do it 'cause it's fun but my strength-to-weight ratio isn't very good and it just wipes me out. More things that I need to work on...IF IT WOULD JUST QUIT RAINING. DOESN'T MOTHER NATURE KNOW THAT IT ISN'T SUPPOSED TO RAIN IN TEXAS IN JUNE AND JULY!?!
