Matt explores the question, 'What Happened?' at this year's IRONMAN World Championships.  Performance predictability and all other signs pointed to a magical day on the Big Island for Sarah Piampiano, a fierce competitor who is coming off her best year of almost a decade in professional racing.

There are no guarantees in sport, which is what makes it so beautiful and painful at the same time.   Copyright 2019 All Rights Reserved
