Molly Seidel has run a lot of loops.

Four loops on a course that wove through Atlanta in the Olympic trials when she qualified for the Olympic Games in her first-ever marathon of February 2020. Nineteen loops in October 2020 as part of the elite-only London Marathon that circled Buckingham Palace (again, and again, and again). And the three loops of the Olympic marathon course in Sapporo, Japan, when she won a bronze medal.
