The most people to row 500 meters in a relay on a Concept II Indoor Rower in 24 hours is 600 achieved at an event organized by Mercyhurst University Mens Rowing team (USA), in Erie, Pennsylvania, USA on 8 March 2013.

Students and faculty from Mercyhurst University and members of the Erie community took part in the relay, with monies raised from the event benefiting Project Kenya, The Kanzius Cancer Research Foundation, & Mercyhurst Rowing as they prepare to travel and compete at the IRA Championships in Sacramento, CA, and the Henley Royal Regatta in England.
