The current record for the 30.6 mile course is 2 h 59 min 45 s, set in 1991 by a University of London Boat Club men's eight. The race was cancelled in 2000, due to that year's fuel crisis, in 2011 due to an unusually prolific growth of water weed, and again in 2020 due to the COVID-19 pandemic. In 2021 the event was again cancelled due to Covid-19, but a solo club rower completed the course on the scheduled day.
