Next event: 2016 TBC
The Boston Marathon was inspired by the marathon run at the first ever Olympic Games in Athens and is regarded as the grandfather of marathons. This year it celebrates its 120th anniversary. What is more, it’s one of the few races that’ll require you to complete a marathon seriously fast (18-34 males need to run 3:05) to be able to qualify for entry.
However this is part of its appeal, and this is s a running event closest to racing at the Olympic Games!
