At the penultimate control of the CSU Orienteering Weekend Middle Distance course, I leapt over a tangle of green briar, rolled my left ankle, and landed with all my weight on it. I paused for about twenty seconds, then hobbled to finish the course. The ankle swelled up moderately and running is difficult.
I do not have a full range of motion in my ankle, and rotating it causes slight pain. I have elected to stop running for some days and spend my time biking gingerly instead.
Rest, ice. I avoided running on it for about a week.
