I looked it up and I had the wrong event. Carbon's Offset rolled his ankle badly 3 weeks before Western States, then had a great run there.
Here is his month of training and physio for June 2013. He rolled the ankle on June 9 and raced WS on June 29. I'm sure he could tell you more about what he did.
