7. Nike
In 2016, Nike featured Sister Madonna Buder in one of their TV ads, who at the time was an 86-year-old nun who had completed 45 Ironman competitions. She ran her first Ironman at the age of 65, and the clip follows a bewildered narrator that watches her enter the triathlon, telling her to turn back because it would be too vigorous for her. She chuckles and answers, "It wasn't the last 44 times."
