While hiking on Saturday, we didn't realize how late it had gotten. All of a sudden, we had almost 2 miles to go and only 15 minutes until sunset. So we started trail running...downhill. We were going pretty fast, and I rolled on my left ankle, twisting it. Had to limp all the way back and made it off the trail after dark. We put ice on it when we got home and I took an Advil. My ankles are the weakest part. I've sprained each ankle once - one while stepping off the curb, and one while doing a flying sidekick over a bunch of punching bags in kung fu class. It's been years since I've twisted it this badly. Now it's wrapped up in an Ace bandage.
