Correct. Less burning, longer/harder efforts before it gets nasty. That's my impression. Confirmed somewhat by my ride up Hook Mtn. last Sunday. I put down a perceived effort that to me was quite similar to what I've done in the past on the climb. But I hung close to guys who typically ride away from me.

Based on that Erik YOU should be able to climb with T. Danielson soon. I will keep you posted.

Is this Optygen? I don't know. But it helps to believe it of course : ).
