To me, a hill is a golden opportunity on a ride to mix it up; get up out of the saddle, mess around at the extremes in terms of cadence, etc. Plus that, I LIVE for aerobic burn... so while it hurts to get there, I find peace, tranquility, and a real ability to massively process my problems of the day while in the highly aerobic fugue-state. Such focus. Such simplicity. Aaahhhhh.
OP: whatever gets you up the hill, is allright!
