A Tuesday afternoon accident on Arguello Boulevard in the Presidio took the life of two-time USA Cycling Masters Track National Champion Ethan Boyes, who was struck by a car under circumstances the U.S. Park Police continue to investigate.

San Francisco resident Ethan Boyes was not just any local bicyclist; he was the USA Cycling Masters Track National Champion in both 2018 and 2019, and held the national record for the 500-meter flying start track time trial. KRON4 reported on Thursday that a cyclist has been hit by a car and killed in the Presidio, and the elite bicyclist community is in mourning as the Chronicle has since confirmed that the cyclist killed was Boyes. He was 44.

Boyes’s final Instagram post from a week ago is seen above, and the comments have become sort of an online memoriam.

“Ethan was a very experienced cyclist and well regarded in the cyclist community,” family spokesperson Shaana Rahman told the Chronicle. “This is a pretty devastating loss for the family and for the San Francisco cycling community.”


Streetsblog has the statement from the U.S. Park Police. “On Tuesday, April 4, 2023, at approximately 4:00 PM, the United States Park Police responded to Arguello Boulevard south of Washington Boulevard for a motor vehicle crash between a car and a bicyclist,” the statement says. “The cyclist, an adult male, was transported to the hospital with life-threatening injuries and later pronounced deceased. The driver of the vehicle was also transported to the hospital for treatment of non-life-threatening injuries. The crash remains under investigation by the United States Park Police."


A Nextdoor post from a claimed eyewitness alleges that “A speeding car heading North careened into the opposite lane and hit a cyclist.” (And there are other worse allegations than “speeding” elsewhere on social media, none of them confirmed.) That post also adds that “The driver was on the side of the road looking dazed and bloody,” which seems to track with the Park Police reports of the driver being hospitalized.

USA Cycling said in a Facebook statement, “Beyond Ethan’s athletic achievements, he was an upstanding member of the American track cycling community. His loss will be felt at local, regional, national, and world events for years, as he brought a mixture of competition and friendliness to every race. Our thoughts are with his family and loved ones.”
