Coen de Koning

De Koning also set a world record in one-hour skating, at 32,370 m in 1906,[4] and won the Elfstedentocht in 1912 and 1917.

His brother Jacobus "Sjaak" Petrus de Koning won the national all-around title in 1914.

His more distant relatives on the brother's side, Truus Dijkstra and Jacques de Koning were also prominent Dutch speed skaters.

** After shared wins in 1933 and 1940, when the front-runners decided not to compete but join hands to cross the line together, this practice was forbidden by the organisation.

Jan van der Hoorn, Aad de Koning, Jeen Nauta, Maus Wijnhout and Anton Verhoeven however ignored this rule when they crossed the finish line in unison.
