The world's oldest annual race of its long-distance kind, first staged in 1897 after the first modern Olympics. It takes place on Patriots' Day, the third Monday in April, from Hopkinton to Copley Square in the Massachusetts capital. Most runners must meet qualifying times. Heartbreak Hill, near the twentieth mile, is its most famous climb. In 1967, Kathrine Switzer became the first woman to finish as an officially registered entrant.
