Are you an uphiller or a downhiller?
Uphillers live for a good climb, attack it with relish, the steeper and longer the better, and then they rest while coasting down the other side as a well-earned reward.
Downhillers tolerate the uphills and live for the thrill of vigorously attacking the downhill. It's all about attack position and speed. Uphills are merely the price to be paid.
