On a cold February day in 2012, Mike McKnight’s running career was almost snuffed out before it got started.  Mike, then 21, and his friends were skiing at Beaver Mountain near Logan, Utah, and set up to hit a table-top jump in the terrain park, one Mike had hit multiple times in the past. But previously, Mike had carved his way into the jump, taking it at a conservative speed.  “I decided to go off of it skis pointing forward, as fast as I could, and see how far I could go.” As soon as the jump ramped up, Mike realized “as fast as he could” was way too fast.  “I panicked, and foolishly I started leaning back to fall over,” he says. “I launched off and landed flat on my back.”  It was an icy day, and the impact was the equivalent of landing on concrete.
