The Official Report states that there were a total of 21 competitors, divided into three groups; there should therefore have been 7 athletes in each heat. The Official Report names only the top two runners, Lane and Szokolyi.Official Report, pp. 61–62. Butler writes that the first heat had "two Hungarians, a Chilian, a Frenchman, a German, an Englishman and an American."Butler, Maynard. The Olympic Games. In Mallon & Widlund, pp. 37–41. Mallon & Widlund list Lane, Szokolyi, Gmelin, Grisel, and Doerry. Megede places André Tournois as the French competitor, rather than Grisel (who Megede does not list at all), omits Doerry (who Megede puts in heat 2), and includes Leonidasz Manno and Luis Subercaseaux.Ekkehard zur Megede : The history of Olympic athletics. Volume 1: 1896-1936. Verlag Bartels & Wernitz KG, Berlin, 2nd edition 1970. Olympedia follows Mallon & Widlund, also including Manno, Tournois, and Subercaseaux in a list of non-starters not attached to particular heats (this list includes 12 athletes, bringing Olympedia's total entrants to 27 rather than 21).
