Katherine - in response to your follow-up question, there are a few form factors to consider: for uphills, your stride should become shorter, and somewhat quicker. Depending on the grade, arm and knee drive up the hill should be more exagerated(porportionate to the grade). Your torso should not be hunched over, but should lean into the hill somewhat. For downhills, avoid overstriding - this usually is indicated by landing with a nearly fully extended knee (not good for the knees and it tends to decelerate you instead of allowing you to roll down the hill). Concentrate on a mild forward lean and bent knees. Oh, by the way, downhills are where side stiches tend to happen - also remember to relax your arms, torso , and breathing.
