indy - I've experienced the same thing you talked about. I'm still trying to find MY best way to make it up hills. Rollers - I attack. Hills - no way. I've done the hit them hard thing - I just blow up. I've done the spin like mad thing - I just blow up. I'm now working on just trying to keep a decent cadence and not downshift too quickly. The other riders in my group still blow by me but I am getting to the top more quickly than before and I usually pass them at the top as they slow way down trying to catch their breath and I just keep going at my speed. Hummm...maybe they are just waiting on me and not trying to catch their breath....no, I hear them breathing hard as I go by. Which is hard to do...it's hard to hear them breathing over my gasping for breath.
