Meredith Fitzmaurice intended to run 13 miles (a half marathon) at the Run for Heroes in Amherstburg, Ontario on Sunday. She wanted to do it as a test run as she wanted to achieve a Boston Marathon qualifying time at a race in Detroit next month.
However, as she was running on Sunday, Fitzmaurice missed a turn for the half-marathon route and ended up running a full marathon. Also, she won.
Her time, clearly, qualified her for the Boston Marathon.
