The Head of the Charles Regatta returns to Boston and Cambridge this weekend, bringing thousands of rowers from around the world to Massachusetts.
The event runs from Friday, October 16 through Sunday, October 18, 2026.
It's one of the biggest sporting events in New England each fall. But even people who have lived in Massachusetts their entire lives might not know much about it.
Here are five things worth knowing about the Head of the Charles.
1. It's The World's Largest Three-Day Rowing Event
The Head of the Charles is the largest three-day rowing competition in the world.
More than 12,000 athletes participate in the event, which features 74 different race categories.
Competitors include high school students, college athletes, experienced adult rowers and some of the best rowers in the world.
The competition takes place on a course that stretches roughly three miles along the Charles River.
2. The Event Dates Back To 1965
The first Head of the Charles took place on October 16, 1965.
Three members of the Cambridge Boat Club founded the event after receiving advice from Ernest Arlett, a rowing instructor at Harvard University.
Arlett suggested holding a race similar to the traditional head races in England.
The event started much smaller than it is today.
It eventually grew into a two-day competition in 1997 and later expanded to three days.
The regatta has since become an annual fall tradition in Greater Boston.
3. Rowers Aren't Necessarily Racing Side By Side
Unlike some rowing competitions, the Head of the Charles uses a time-trial format.
Boats generally start about 15 seconds apart and race against the clock.
That means the first boat to cross the finish line isn't necessarily the winner.
Instead, officials compare how long each crew takes to complete the course.
The winding river also makes the competition challenging. Rowers have to navigate turns and bridges while trying to maintain their speed.
4. You Can Watch Without Buying A Ticket
One of the appealing parts of the Head of the Charles is that spectators can watch much of the competition for free.
People can gather along public sections of the river in Boston and Cambridge to see the boats.
The official spectator guide identifies several popular places to enjoy the event.
The Weld Exhibition offers food and merchandise. The Riverbender is another gathering place for spectators and rowing fans.
Visitors can also check out the Rowing and Fitness Expo near the finish line.
Some special hospitality areas require paid admission, but buying a ticket isn't necessary to enjoy the races from public viewing areas.
5. The Event Means Road Closures And Parking Problems
The regatta attracts tens of thousands of spectators, which means getting around parts of Boston and Cambridge can be difficult.
The Massachusetts Department of Conservation and Recreation has announced road restrictions for the event.
Memorial Drive will close in both directions between Western Avenue and Fresh Pond Parkway from 7 a.m. Saturday, October 17 through 9 p.m. Sunday, October 18.
Parking will also be prohibited along that stretch during those hours.
Organizers encourage visitors to take public transportation because parking near the competition is limited.
A Massachusetts Fall Tradition
The Head of the Charles has grown considerably since its first race more than 60 years ago.
Today, it brings athletes, families and rowing fans from around the world to the banks of the Charles River.
Whether you're interested in competitive rowing or simply looking for something to do this weekend, the regatta offers an opportunity to enjoy one of Massachusetts' best-known fall events.
