2024 Outlook: Marks doesn’t get nearly the recognition she deserves. With five Paralympic medals (two golds), she’s one of Team USA’s most decorated active athletes. She also holds five world records and nine American records. And Marks had a stellar year in 2023, winning two World Championship medals and registering top-three times in all five disciplines. That gives her a realistic chance of equalling or exceeding her three-medal haul from the Tokyo Paralympics.
