The press was filled with articles about Carlisle’s expected participation in the upcoming games. Various track meets, competitions and races winnowed the field down to those who would eventually participate.
The Boston Marathon, which was run on April 20, was used to select the U.S. long distance team. Prior to the race Pop Warner thought that Mitchell Arquette, St. Regis Mohawk, would do even better than Tewanima. However, Michael J. Ryan, of the Irish American A.C. unexpectedly won the race and in world-record time. Andrew Sockalexis, Penobscot from Maine and not enrolled at Carlisle, came in second in conditions so muddy that runners had to run on sidewalks to get decent footing. After the conclusion of the race, the U.S. Olympic marathon team was set: Ryan and Sockalexis were selected as was Lewis Tewanima, the only Carlisle distance runner on the 1912 U.S. Olympic team. Apparently, the other Carlisle distance men didn’t do well enough in spring meets to qualify.
Jim Thorpe had a good spring. He was running so well that Warner was quoted as saying , “the man who beats him in the 120 yard [hurdle] event at the Pennsylvania relay meet will have to stagger the world’s record.” In May Thorpe competed in a tryout for the Olympic Pentathlon, a new event that consisted of five track and field competitions: 1) Running broad jump, 2) javelin throw with best hand, 3) 200-meters flat race, 4) discus throw with best hand, and 5) 1,500-meters flat race. He had not thrown the javelin previously but was expected to pick that up quickly. Also new to him was the 1,500-meters run in which his stamina was expected to carry him. Thorpe easily qualified for the Olympic team by winning three events: broad jump, discus and 200-meter run. He placed second in the other two, losing to the national champion in the javelin and finishing two yards behind the leader in the 1,500-meters. His prospects for a successful Olympics were good. Also named to the U.S. team to compete against Thorpoe in the pentathlon and decathlon was Avery Brundage.
