Ran up and back in city creek to gauge how well my knees will tolerate downhill running. During the 3 miles up I ran 11:44/mile and average HR 171 bpm. On the trip back down I ran 10:35/mile with an average HR of 165 bpm. After that I walked a mile to cool down. While going up I only felt fatigue in my hips and didn't feel my knees at all. Going down I did feel some slight dixcomfort in my knees. I checked the change in altitude at the bottom and top of my run -the difference was 460 ft. Averaged on a per mile basis, this should be the gradient I will see at Bryce canyon. Is it better to lean slightly downhill or back into the hill when running downhill? |
