Shelby Houlihan, an American Olympic runner who competed at the 2016 Rio Games and later faced a hotly debated four-year ban, was back on the podium on Saturday.
Houlihan won a silver medal at the World Indoor Championships in the 3,000-meter event in Nanjing, China. She was unable to compete in the Tokyo Olympics and the Paris Olympics because she tested positive for a performance-enhancing drug. Houlihan claimed at the time the positive test was a result of a tainted pork burrito she bought from a Mexican food truck.
