Cogwagee (Thomas Longboat) (June 4, 1887 – January 9, 1949) was an Onondaga distance runner from the Six Nations of the Grand River First Nation Indian reserve near Brantford, Ontario, and for much of his career the dominant long distance runner of the time. When he was a child a Mohawk resident of the reserve, Bill Davis, who in 1901 finished second in the Boston Marathon, interested him in running races.
He began racing in 1905, finishing second in the Victoria Day race at Caledonia, Ontario. His first important victory was in the Around the Bay Road Race in Hamilton, Ontario in 1906, which he won by three minutes. In 1907 he won the Boston Marathon in a record time of 2:24:24 over the old 24-1/2 mile course, four minutes and 59 seconds faster than any of the previous ten winners of the event. He collapsed, however, in the 1908 Olympic marathon, along with several other leading runners, and a rematch was organized the same year at Madison Square Garden in New York City. Longboat won this race, turned professional, and in 1909 at the same venue won the title of Professional Champion of the World in another marathon.
His coaches did not approve of his alternation of hard workouts with “active rest” such as long walks. When he was a professional, these recovery periods annoyed his promoters and the sports press often labelled him “lazy,” although the practice of incorporating "hard", "easy", and "recovery" days into training is normal today. Because of this and other disputes with his managers Longboat bought out his contract, after which his times improved.
Longboat's chief rival was Alfred Shrubb, whom he raced ten times, winning all the races at 20 miles or more and losing all those at shorter distances. He served as a dispatch runner in France in World War I while maintaining a professional career. He retired following the war.
