The Boston Marathon, which began in 1897, is the world's oldest annual marathon. Each year, more than 20,000 people run the course that winds its way from Hopkinton, Mass. to Copley Square in Boston. Boston College, located on Commonwealth Ave, is at the Mile 21 mark, a critical juncture for runners because it comes on the heels of the race's most difficult portion, Heartbreak Hill.
A number of Boston College students participate in the marathon, many of them running to raise money for charity.
