Sydney McLaughlin described her relationship with Dalilah Muhammad as "iron sharpens iron." The two best 400m hurdlers in the world push each other to greater and greater feats, and that was put on display in the finals in Tokyo as they crossed the finish line 1-2, with McLaughlin taking home the gold and a new world record. The first person to embrace her afterwards? Muhammad, of course. "There is no bad blood," McLaughlin said. "It's just two athletes wanting to be their best and knowing there is another great girl who is going to get you there."
