The Greeks were very enthusiastic about this new event and decided to hold qualifiers for the marathon. These races were started by Colonel Papadiamantopoulos, who Louis previously served under in the military. The first qualifying race—the first ever marathon race—was held on 22 March, and was won by Charilaos Vasilakos in 3 hours, 18 minutes. Louis participated in the second qualifying race, two weeks later, and placed fifth. Papadiamantopoulos, who knew of Louis's talent in running, had convinced him to try out.
