Well, since I personally know Kim and Jessica, one thing I can add is the mental toughness they and other ultra runners have. I’ve seen both of them looking like shit less than half the distance to the finish, but the keep going and finish. It may not be podium, but who cares? Sometimes they need a gentle nudge to get it off the aid station and other times they need a kick in the ass, but they keep going. These women, like other ultra runners know the sport is 60% physical and 80% mental, with a little help from their friends.
