Karissa Schweizer comes from a family of collegiate runners: her parents, Mike and Kathy Schweizer, ran collegiately, and so did her grandfather, who was a Division-II All-American. Karissa Schweizer was named the most decorated female athlete in the University of Missouri’s history. Schweizer’s PRs are roughly the same as her boyfriend’s—sometimes even marginally faster—which is impressive because he was also a Division I distance runner, for Gonzaga.
