The story of the 2012 Olympian Gabrielle Douglas.
During the summer of 1924, the Olympics were hosted by the city of Paris. Liddell was a committed Christian and refused to run on Sunday, with the consequence that he was forced to withdraw from the 100 meters race, his best event. The schedule had been published several months earlier, and his decision was made well before the Games began. Liddell spent the intervening months training for the 400 meters, an event in which he had previously excelled. Even so, his success in the 400m was largely unexpected. The day of 400 meters race came, and as Liddell went to the starting blocks, an American masseur slipped a piece of paper into Liddell’s hand with a quotation from 1 Samuel 2:30, “Those who honor me I will honor.” He not only won the race, but broke the existing world record with a time of 47.6 seconds. A few days earlier Liddell had competed in the 200 metre finals, for which he received the bronze medal behind Americans Jackson Scholz and Charles Paddock, beating Harold Abrahams, who finished in sixth place. (This was the second and last race in which these two runners met.)
