Clarke was one of the world’s top shot putters for several years, winning four NCAA champions at Arizona State and becoming the only Alaska to break the 70-foot barrier. He won a gold medal at the 2014 Pan Am Games and placed third at the 2015 U.S. championships with a person-best throw of 70-6. At Bartlett High, Clarke set two state records that have never been threatened — 192-3 in the discus and 71-3 in the shot put (set with a 12-pound shot; a 16-pound shot is used in college and beyond).
