Through the 2016 Rio Paralympics all races were raced over a 1000 m[1] straight course. Beginning with the 2020 Tokyo Paralympics, competition is raced over the same 2000 m course as the Olympics. [2]
Qualification
There is a limited number of crews permitted to race, so the International Rowing Federation holds qualification events in order to determine who competes at the Paralympic Games. At the Paralympic Games, each National Olympic Committee can only have one boat per event.
