Rowing on Boston’s Charles River: HOCR and its Winter Erg Challenge
read
Every rower dreams about rowing on the Charles River or even participating in the Head Of The Charles Regatta (HOCR). There are many reasons why the world’s biggest rowing event is held at Boston’s main waterway. Read the article to find out what makes the Charles River such an exciting regatta location and how you get to participate in the HOCR’s 2026 Winter Erg Challenge with EXR.
The Charles River: from polluted past to urban oasis
Centuries ago, well before colonists set foot on its shores, Native Americans already considered the 129-kilometer-long Charles River a vital part of their lives. Originally named the Massachusetts River, it was later renamed by King Charles I after himself. In its more recent history, the Charles River was notorious for being highly polluted with sewage water streaming into Boston’s waterway. Fortunately, great efforts in environmental conservation and water quality management have led to significant improvements, transforming it into the clean river we know today.
Nowadays, the Charles River plays a pivotal role in Boston's infrastructure with its shores hosting a variety of recreational and educational facilities. The riverbanks feature relaxing state parks and event locations such as the Hatch Shell where the annual Fourth of July concert is held. From vantage points on the riverbanks, you can also spot two of the world’s most famous universities: Harvard University and the Massachusetts Institute of Technology. Due to the Charles River’s gentle current, it’s an ideal spot for both amateur and pro water sports such as kayaking and rowing. The proximity to the university led to a line-up of boathouses including the Boston University’s DeWolfe Boathouse and the Northeastern University’s Henderson Boathouse.
What makes the Head Of The Charles Regatta so unique
The Head Of The Charles Regatta is the world’s largest international rowing competition spanning 3 days. It’s famous for its spectacular setting and challenging course. Held every October, this prestigious event draws thousands of athletes, vendors, and spectators.
Since the regatta’s conception in 1965, the 3-mile race has evolved into one of the most esteemed rowing events attracting participants and teams of all nationalities, ages, and capabilities to compete for one of the iconic Head Of The Charles Medals. Over the years, the regatta has become a highlight for locals, (indoor) rowing brands, and rowing enthusiasts alike to connect over their passion for the sport. In 2023, EXR and Fluidesign attended the HOCR together to represent innovative rowing on and off the water.
While Boston forms a beautiful backdrop for the competition, the Charles River itself is considered rather difficult to navigate due to its many bridge pillars and winding turns. Irish Olympian Philip Doyle describes his first HOCR race as chaos: "Besides the difficult course, there are so many people shouting at you and buoys reminding you to steer clear of the pontoon and bridges. You really have to look out for all the corners and obstacles!" Before the race, competitors are instructed which bridge arches they’re allowed to use in what specific situations. Taking certain shorter routes may lead to time penalties. As a result, ever so often boats crash into each other, shattering not only the dream of crossing the finish line first.
