Harold Osmer & Phil Harms Real Road Racing: The Santa Monica Road Races, Harold L. Osmer Publishing: Chatsworth, CA 1999, 1911, 1910, 1910s, 1909
"The 1911 Santa Monica race was held on October 14.
"Bert [Dingley] has been readied for the race today by Roger Cornell, who is probably the greatest physical conditioner in America, and who has prepared most of the big fighters for their supreme contests.
"Every day Dingley has been rubbed down with an electric vibrator to steady his nerves, and his hands and arms have had special treatment. Between races, Cornell will take care of him much after the manner that boxers are restored in their corners between rounds." Los Angeles Times
