The Head of the Charles starts on Friday, with organisers expecting around 12,000 competitors on the river and up to 400,000 spectators along its banks between Boston and Cambridge over three days, supported by 2,400 volunteers. For many crews, it is a bucket-list event, but for first-timers it’s a lot to take in.
Row360 enlisted four experienced racers to guide you through the Head of the Charles weekend. Our guides are Olympic silver medallist Jess Eddie, Paris Olympic champion Sholto Carnegie, Tokyo Olympian and Cambridge coach Matilda Horn, and Oxford Brookes coach Morgan Baynham-Williams, a winning cox at the Boat Race, Henley Royal Regatta and the Head of the Charles.
Eddie has been coming most years since 2007 and describes it as Pairs Head, Scullers Head, the Head of the River and the Women's Head of the River squeezed into one week, with internationals and juniors on top.
Here is what you need to know, whether you are sitting in a boat or standing on a bridge.
The basics
When is the 2026 regatta?
Racing runs from Friday 16 to Sunday 18 October 2026 on the Charles River. The first regatta was held on 16 October 1965, so this year marks its 61st anniversary.
How did the regatta begin?
With an English idea. Harvard's sculling instructor Ernest Arlett proposed a head-of-the-river race on the Charles, in the tradition of those in his native England. Three Cambridge Boat Club members — D'Arcy MacMahon, Howard McIntyre and Jack Vincent — took up his suggestion and created the regatta, first held on 16 October 1965 with 237 rowers.
How does a head race work on the Charles?
Crews start one after another, typically 10 to 15 seconds apart, and race the clock over the full course. The fastest elapsed time wins. Overtaking is part of the sport here rather than an occasional event, and the bridges make it complicated. "There's lots of overtaking, there's lots of jeopardy, there's lots of going through bridges. Anything can happen," says Eddie.
"With head-style racing, there's a lot of overtaking boats. If you're more than ten seconds faster than the boat ahead of you, you'll be passing them," Harvard rower Olivia Sullivan told The Harvard Crimson last year. "There can be five seconds separating the top 10 boats."
Results are confirmed once the timing team has processed them, so do not expect to know who has won immediately from the towpath.
What is the course like?
It is 4,702 metres, nearly three miles, upstream from Boston University's DeWolfe Boathouse to the finish at Herter Park. That odd distance has a story of its own, which we told in HOCR 4702.
Crews pass under seven bridge structures: the Grand Junction Railroad Bridge and the BU Bridge almost immediately after the start, then River Street, Western Avenue, Weeks Footbridge, Anderson and Eliot. Between River Street and Western Avenue lies the Powerhouse Stretch, the only real straight. Weeks sits on a sharp 90-degree turn. The long bend that ends at Eliot is the big one, and from Eliot it is a sprint to the line.
Watching
Where are the best places to watch?
There is no single best spot, and the river feels different at every point along it.
- The start: watch crews queue from the Dr Paul Dudley White Bike Path, or look over the basin and the start from the BU Bridge.
- Magazine Beach: next to Riverside Boat Club and the singles and doubles launch, and the quietest stretch of the course.
- River Street and Western Avenue bridges: views down the Powerhouse Stretch and crews setting up for Weeks.
- Weeks Footbridge: one of the most popular viewing points, directly above the 90-degree turn. Good for watching coxes get it right or wrong.
- Weld Exhibition at Riverbend Park: the main food and vendor area, looking over the racing between Weeks and Anderson, about a seven-minute walk from Harvard Square station.
- Eliot Bridge and beyond: the big turn and the run to the finish, with Cambridge Boat Club, the regatta's headquarters, at the bridge.
- Herter Park: the finish line, Attager Row and the busiest crowds.
The closer to the finish you go, the busier it gets, and the bridges fill up as the day goes on.
Do spectators need a ticket?
Not to watch from the riverbank. Some hospitality areas require paid access. The Eliot Bridge Enclosure, upstream of Eliot Bridge, is ticketed and purchasers must be 21 or over. The Riverbender, on the Boston side between Weeks and Anderson across from Harvard Business School, offers beverages, DJs, lounge seats and games on the lawn. Community Rowing's spectator tent requires a badge, even for competing athletes. Badge sales closed on 13 October, with only a very small number potentially available on the day, depending on capacity.
What else is there apart from the racing?
Attager Row ("regatta" backwards) at the finish is home to athlete registration, the awards tent and the Rowing and Fitness Expo, with more than 40 rowing vendors. Next door, FALS Bar serves food and is open to all spectators; anyone 21 or over can buy alcohol there. USRowing's tent, on the bank between Eliot Bridge and the finish, is free to visit during racing, although some of its scheduled sessions need registration.
Sculptor Joe Brown created the Head of the Charles medal for the inaugural regatta in 1965, and its design has not changed, so the award ceremonies are worth catching.
When does racing start?
The first event on Friday, the Men's Grand Master Doubles, is listed for 7.35am. The schedule on RegattaCentral is marked tentative, so check it and the draw again on the morning of any race you want to see.
Among the British contingent, Cambridge University Boat Club is bringing six crews, and its men's Championship Eight A crew is chasing a third consecutive title. Last year's racing is in our 2025 regatta coverage.
Getting there
What is the easiest way to get to the course?
Use the T. Harvard and Central stations on the Red Line and BU Central on the Green Line's B branch are all within walking distance of the course. Bus routes 1, 47, 64, 66, 71 to 75 and 86 serve the area. From Logan Airport, take the Silver Line 1 to South Station and change to the Red Line. The regatta has also flagged construction work along the river this year, so check the current spectator information and live MBTA service before setting off.
Can I drive?
You can, but the regatta advises against it. Harvard Stadium, Gate 14, has about 500 spaces at $40 a day, cashless only. It is open from 6am to 7pm on Friday, 10am to 7pm on Saturday and 6am to 6pm on Sunday, and fills quickly. The Alewife garage at the end of the Red Line is a cheaper park-and-ride, but published rates differ, so check before you go.
Memorial Drive is closed between Cambridge Boat Club and Western Avenue from 8am to 7pm on Saturday and Sunday.
How should I plan to get around on foot?
Expect to walk a lot. Eddie's first piece of advice: "Get your walking shoes on."
The river bends back and forth through Boston and Cambridge, and it is easy to lose your bearings between Weeks, Anderson and Eliot. Following the bank is often the long way round. "So always look what the shortest path is. If you want to get somewhere, don't just follow the river. You might be taking a whole loopy loop," she says.
She also recommends a detour to the boathouses, from BU at the start to Radcliffe and Harvard's Weld. "They're huge institutions with incredibly unique rowing spaces."
What should I bring?
Layers and waterproofs, whatever the forecast says on Thursday. October weather in Boston varies enormously. "It snowed on me in 2009. It's been boiling hot for some years," says Eddie, who also remembers torrential rain a few years ago.
Grass gets wet and fingers get cold, so waterproof shoes and gloves are worth packing, along with a phone charger.
"Bring far more warm kit than you think you need. October in Boston can go from sunny to freezing in an hour, and you'll spend a long time sat on the water waiting at the start," says Carnegie, who first raced the Charles before going to Yale. "Fly with your unisuit in your hand luggage. If the worst happens and your hold bag goes missing, you can borrow almost everything else, but tracking down an extra unisuit is harder to do!"
He suggests packing your usual pre-race snack from home, because you may not find it in the US. Have a bag of dry clothes ready at the finish, too.
Racing
Which course rules catch visiting crews out?
The buoys and the arches. From the cox's seat, the Cambridge shore is on your right (starboard) and the Boston shore on your left (port). A continuous line of orange buoys marks the Boston-side boundary. Green buoys mark the Cambridge side in places: at Magazine Beach, the Eliot turn and the finish. Where there are none, the Cambridge shore is the boundary.
At the railroad trestle, the second arch from the Cambridge shore is the mandated lane. The centre arch is preferred at the remaining bridges, and at three of them the Cambridge-side arch can be used when the centre is congested. The exceptions are Anderson and Eliot, where the Cambridge-side arch is out of bounds. Going through the Cambridge-side arch at the trestle, Anderson or Eliot, or through any bridge's Boston-side arch, costs 60 seconds, on top of any buoy penalties.
Blades can cross the buoy line, but the hull, including the bow ball, must stay within it. Buoy penalties add up quickly: five seconds for the first missed buoy and ten for each one after that.
The regatta strongly advises every cox and sculler to attend its coxswains' clinic.
How should coxes approach the course?
Morgan Baynham-Williams, Oxford Brookes University Boat Club's lead men's coach, has won the Boat Race, Henley Royal Regatta and the Head of the Charles as a cox:
"It's a coxswains race. For every 200m extra you will need to go approx four seconds faster per 500m on average split to hit the same time as the course records."
"It's a race about driving the now for the future," she says. "You might be on the inside of the current turn, but are you going to get stuck in and be on the outside of the next turn?"
Matilda Horn, a Tokyo Olympian who spent six years as a GB cox and now coaches at Cambridge University Boat Club, emphasises the importance of planning ahead. "From a coaching perspective it's about preparing your coxes to think ahead and plan for a multitude of scenarios."
Arches have finite width, and the stretch between Weeks and Anderson is where crews tend to converge. Keep calm: it is better to ease off the pressure or even pause to avoid a collision than get caught up in a clash. Clashing costs more time than a few light strokes, and umpires can penalise it as interference.
You also need to be able to ask for room. "You've got to learn how to shout yield!" says Eddie.
What is it like to row?
Horn describes the race from a rower's perspective: "It's not long enough of a course to get comfy, but I'm not sure any race track is, there are some quieter patches to knuckle down through and grind and there are some eventful and exciting patches where it's imperative to stay process driven."
"Enjoy it!" says Carnegie. "The atmosphere along the bank is unlike any head race at home, and the noise under the bridges is something you'll remember."
What do crews need to know about launching?
Most visiting crews launch from the Finish Area Launch Site (FALS). The regatta requires a firmly fixed bow ball and, with traditional foot stretchers, heel ties. Have oars ready and gates open before you reach the dock. Keep shoes with the crew or its boat representative (thanks, coach): you may land at a different dock from the one you launched from. Only competitors and one boat rep may access the docks and launch areas, and volunteers run launching and landing.
The row up to the start is stop-start. Know your bow number so you can answer the marshals immediately.
Carnegie suggests leaving plenty of time for everything. "It's a huge regatta, with crowds, launching queues and logistics that take longer than at any British head race."
Are the events and boat formats different from home?
In places, yes. HOCR has its own Club, Collegiate, Alumni/Alumnae, Youth, Masters, Lightweight, Championship and Para/Inclusion divisions, each with specific eligibility rules. Institutions from outside North America must contact the regatta before applying for Collegiate events. Masters age is calculated as of 31 December. Rowers must be at least 30, with the crew's average age setting the category in doubles, fours and eights. Lightweight limits are 160lb for men's singles and 165lb for men's crew boats; 130lb for women's singles and 133lb for women's crew boats. There is no averaging.
For British juniors, the main difference is the quad. HOCR's youth quads are coxed, unlike the coxless quads J16 and J18 crews usually race at home.
The British in Boston
British crews are no tourists here. In 2024 Cambridge University won the men's Championship Eight and Leander the women's, the first time British crews had taken both, with 11 more British crews winning gold across the other events. Last year Cambridge successfully defended the men's Championship Eights title, and St Paul's School and Windsor Boys' School both won youth events. The 2025 regatta drew 2,685 crews from 852 clubs in 25 countries. Our coverage of last year's racing has the full story.
Expect the usual British mix again: university crews, schools, clubs, alumni, masters and the occasional family boat.
The course, bridge by bridge
The course passes under seven bridges, or six if you count the paired BU Bridge and Grand Junction Railroad Bridge as one. The regatta counts them separately.
The start and the BU bridges. Crews start just in front of the BU Boathouse and head straight for the railway and BU Bridge combination. There is no passing before the bridges. The railroad bridge's steel is covered in graffiti, and the red-and-white tag above the racing arch gets a motivational update each year from people in Boston's collegiate rowing community whose identities are unknown. The regatta says it is among only three places worldwide where a rower on the water can pass beneath a train, with a car above it and a plane overhead.
Magazine Beach. Out of the bridges the river bends. The river is wider here, but resist being pulled wide: set up for the inside of the turn and don’t get dragged towards the Boston shore through the turn and the Powerhouse Stretch.
River Street and Western Avenue. These two bridges span the Powerhouse Stretch, the course's only real straight. Crews may use the right or centre arch here, depending on traffic. The mile marker sits between the two, a painted stripe on the retaining wall.
Weeks Footbridge. The first big test: a sharp 90-degree turn that is hard enough alone and far harder with several crews jostling for it. Many coxes use the 'turning tree' on the approach, golden in October, as the cue to start the turn. With no boats nearby, the cox's ideal line keeps the port blades narrowly clear of the bridge's upstream corner, with the turn largely done before the bridge so the boat points straight at the centre arch of Anderson.
Anderson Bridge. The sixth bridge, beside Harvard's Weld Boathouse, and the stretch where coxes most need eyes in the backs of their heads. The right arch is out of bounds here. Crews hugging the Cambridge shore and crews that swung wide can converge on the far side of the bridge. Be ready for congestion and collisions: play it safe and stay vigilant.
Eliot Bridge. The big one: a long, sweeping turn that ends at the final bridge, in front of regatta headquarters at Cambridge Boat Club, and opens the last 800 metres. Get pushed out to the Cambridge shore and you take the long way home.
Eliot to the finish. The river widens again, and the Boston shore pulls at crews once more. Keep the starboard oars just off the Belmont Hill/Winsor dock, which will be heaving with spectators, before aiming between the two finish buoys rather than following the shoreline as it bends away in the last 100 metres.
See you on the Charles
Whether you're racing or cheering from the bank, leave time to enjoy Boston in the fall: the boathouses, the Halloween displays, pumpkin spiced lattes, clam chowder and the occasional lobster roll.
Row360 will be on the ground, so look out for our regatta coverage. In the meantime, enjoy the weekend — and mind the arches.
