Captain Aiken has acquired considerable celebrity as a swift runner, and for any distance under five miles, his performances have been seldom exceeded. He undertook three matches for fifty guineas each: 1st, To run one hundred yards within twelve seconds; 2d, To go two hundred yards in twenty-eight seconds; and, 3d, To do a quarter of a mile in one minute and twenty seconds. He started on the Uxbridge road, on the 23d of June 1809; and the first match he lost by a second; the next he won with difficulty; and the third, he gained by two seconds. He performed a quarter of a mile on the Twickenham road, in one minute and fifteen seconds; and on the 26th of July 1809, he started for two bets of twenty guineas each; first, to go a mile in five minutes, and after an interval of one minute, to run a mile against Mr. Sullivan. The first he accomplished in two seconds under the time; and the second he performed in five minutes and twenty-five seconds, beating his antagonist by about one hundred yards. In the month of November the same year, he ran four miles on a spot of ground near Maidenhead, in twenty-three minutes and fifty seconds, for a wager of one hundred guineas. On the 5th January 1810, Captain Aiken beat Mr. Athol by one hundred yards on a mile, which he performed in five minutes and twelve seconds; and on the 19th of November, he did five miles in twenty-nine minutes and fifty-four seconds, for a wager of fifty guineas. He also performed one mile and a half within eight minutes, on the 4th of March 1812, at Ashford, for a bet of one hundred guineas. Lieutenant Fairman is a noted pedestrian, but his performances are not so astonishing as those of many others, who of late years have distinguished themselves either by their great strength, or uncommon agility. He is remarkable, however, for undergoing a great deal of fatigue without any refreshment.
