For most elite ultra runners, a sponsorship deal provides a chance to focus solely on training and improving performance while increasing their profile and of course, helps with the cost of travel to compete in races. It's not an easy thing to give up, but world champion sky runner Francesco Puppi did exactly that when he parted ways with Nike recently.
In an announcement on Instagram, the Italian sky runner says he decided to leave Nike after watching an ad titled Winning Isn't for Everyone that aired during the Paris Olympics.
