The New Charles River Run is an annual running event consisting of three simultaneous races, 5 km, 7.5 miles and 7.5 mile relay, which takes place in Boston, Watertown and Cambridge, MA the last Sunday in June. Both courses are run entirely along the Charles River, making them extremely flat and fast. A post-race party at the finish line features awards in 21 divisions, music, raffle, beer, barbecue, and ice cream. The race has grown quickly, from 213 7 mile finishers and 126 5 km finishers in 2001 to 1097 7.5 mile finishers and 641 5 km finishers in 2008.
