Understanding Hills


Like Eskimos are said to have many words for snow, it seems to me that cyclists ought to have many words for hills. After all, what does it really mean when terrain is described as "hilly?" There are the short city hills that only seem like hills when I ride my upright 3-speed, there are the long and annoying false flats, the rollers, the twisty hills, the mountain passes.My perception of hills also changes over time. Rides I considered hilly a year ago, I now think of as "mostly flat," in light of some other hills I've ridden. And then I get annoyed at myself, because I remember when others described those rides as "mostly flat" and I felt bad, because to me they certainly seemed hilly. Hills are a fluid concept.





The more hills I ride, the more I realise that steepness and duration alone are not what makes them easy or difficult for me. More than anything, the pattern of grade change can make all the difference between enjoying the challenge of the climb and hating it. On a hill with a consistent grade, I can "settle into" the climb, whereas a hill with erratic grade changes drains my energy much faster. In the picture here I am standing atop of a relatively mild, but much despised hill after just having climbed it. It's hard to explain why I hate this stretch of incline so much, but it messes with my head. Starting immediately after a traffic light near the center of Lexington, it initially acts like a normal hill and as I near the top, I feel a sense of accomplishment: almost made it. But just as I reach what appears to be the crest of it - and this gets me every time - not only does it continue, but suddenly it becomes steeper. That last stretch, usually with my gearing already maxed out, just always manages to drain my morale. By comparison, the nearby Page Hill is a more significant climb. But I find it easier to handle, because the grade transitions it goes though somehow feel more logical.



Lat week I got a new computer and it has this feature that shows the grade percentage. This little toy has made me ridiculously excited and I am finally getting a sense for what different grades feel like. It also allows me to quantify my suffering. A climb starts to feel effortful at 6%, difficult at 10% and when I got the "Mommy can I go home now?" feeling I glanced down to see 14%. I was also surprised to learn that the "flat" Minuteman Trail reaches a 4% grade in a couple of the false flat stretches. Are you falling asleep yet at this fascinating information?



I am told that lots of cyclists start out hating hills, but then grow to enjoy them more and more. It could be that I am in that category... how else could I enjoy making a game of guessing the grade?
