120th Boston Marathon on April 18, 2016. DISTANCE: 26 MILES, 385 YARDS (42.195 KILOMETERS). The Boston Marathon is the world's oldest annual marathon and ranks as one of the world's most prestigious road racing events. The Boston Athletic Association manages this American classic, which is sponsored by John Hancock Financial Services. The Boston Marathon has distinguished itself as the pinnacle event within the sport of road racing by virtue of its traditions, longevity and method of gaining entry into the race (via qualification).
About the only thing known for sure is that the 119th Boston Marathon will be held on Monday, April 20, 2015. As for everything else, the initial discussions about next year are already underway. But itâs unlikely the race will return with a field of approximately 36,000 runners in 2015.
