The Horseshoe trails are a minefield for ankle twists. I sprained my ankle really badly on those trails three weeks before my first race with Wild Rose. Grrr! Barely recovered in time, raced with a brace. And I've since rolled an ankle at least once more on those trails.
I hope your ankle isn't too bad and heals quickly.
Sending healing thoughts! Remember my bad ankle twist on the Hockley Loop when we were running together? Grrr, stupid ankles.
My ankle is not happy today....will do some stretches and hopefully it will help.
