The Head of the Charles Regatta is this weekend, when more than 9,000 rowers and 300,000 spec­ta­tors will flock to the Charles River for the two-​​day rowing com­pe­ti­tion. Races are all day Sat­urday and Sunday from 8 a.m. to 5 p.m. Here are five things you should know about the regatta and Northeastern’s participation.

1. The Head of the Charles started in 1965 and was spear­headed by Ernest Arlett, Northeastern’s first rowing coach. He was also the sculling coach for the U.S. Olympic team at the 1976 Summer Olympics. That same year Arlett was inducted into the North­eastern Uni­ver­sity Ath­letics Hall of Fame.

2. The regatta’s course starts at Boston University’s DeWolfe Boathouse on Memo­rial Drive in Cam­bridge, and ends about three miles upstream near Northeastern’s Hen­derson Boathouse on Sol­dier Field Road in Allston.

3. On Sat­urday, North­eastern will go for an unprece­dented fifth straight vic­tory in the Men’s Alumni Eights race, which the team has won every year since the race’s incep­tion in 2009. At the 2012 regatta, the North­eastern alumni crew set a course record with a race time of 14:49.25.

4. There are 55 dif­ferent races this weekend. In pre­vious years North­eastern has fielded teams in the Men’s Alumni Eight, Women’s Alumni Eight, Men’s Club Eight, Women’s Club Eight, Women’s Cham­pi­onship Four, Men’s Cham­pi­onship Eight, and Women’s Cham­pi­onship Eight.

5. It is strongly rec­om­mended that spec­ta­tors take public trans­porta­tion to the course, which you can get to from the BU Cen­tral stop on the Green Line and the Cen­tral and Har­vard stops on the Red Line. Spots any­where along the Charles River will give you a good view of the races, or you can watch from one of the many bridges that span the Charles River.
