Context: The evolution of triathlon as a distinct sport is difficult to trace with precision. Many, including triathlon historian and author Scott Tinley, consider events in early twentieth century France to be the beginnings of triathlon, with many three element multisport events of differing composition appearing, all called by different names. The earliest record for an event was from 1901 in Joinville-le-Pont, Val-de-Marne: it called itself "Les Trois Sports" (The Three Sports). It was advertised as an event for "the sportsmen of the time" and consisted of a run, a bicycle and a canoe segment. By 19 June 1921, the event in Joinville-le-Pont had become more like a standard triathlon, with the canoe segment being replaced with a swim. According to the newspaper L’Auto, the race consisted of a 3 km (1.9 mi) run, a 12 km (7.5 mi) bike ride and the crossing of the river Marne, all staged consecutively and without a break. Throughout the 1920s other bike, run, and swim events appeared in different cities, such as the “Course des Trois Sports” in Marseille and "La Course des Débrouillards" in Poissy. These multisport events would continue to slowly spread and grow in popularity: by 1934 "Les Trois Sports" was being hosted in the city of La Rochelle, though it consisted of three distinct events, swimming a 200 m (660 ft) channel crossing, a 10 km (6 mi) bike competition around the harbour of La Rochelle and the parc Laleu, and a 1.2 km (0.75 mi) run in the stadium André-Barbeau. Throughout this growth with new events appearing no unified rules ever existed and as a whole triathlon would remain a minority event on the world stage


Question: Given this paragraph about the history of triathlon, what is the earliest known triathlon event.

Triathlon events have evolved of the years, and its origins are not fully known. Triathlon historians have evidenced multisports events dating back to 1901. In this era "Les Trois Sports" did not include the swim as it does in modern day triathlon, but instead included a canoe discipline. As the name suggest, triathlon appears to have first surfaced in the history books in france in the suburbs of paris known as Joinville-le-pont, Val-de-marne.
