The marathon may be about to gain a new symbolic date. The Association of International Marathons and Distance Races (AIMS) has announced its intention to mark 15 September each year as World Marathon Day<\/strong>, commemorating the letter in which Michel Br\u00e9al proposed a race from Marathon to Athens in 1894.<\/p>\n\n\n\n

The initiative comes with something more tangible than a label. AIMS has funded the complete restoration of Br\u00e9al\u2019s grave at Montparnasse Cemetery in Paris and a new commemorative headstone. The restored site is due to be unveiled on Tuesday 15 September 2026.<\/p>\n\n\n\n

The announcement also offers a useful chance to untangle a history often told as a blend of legend, ancient sport and the modern distance. The marathon was not an event at the ancient Olympic Games, the first Olympic race in 1896 was not 42.195km, and Br\u00e9al was not even a runner. That is precisely what makes his role so unusual.<\/p>\n\n\n\n

What AIMS has announced<\/h2>\n\n\n\n

In its official announcement<\/a>, AIMS says it intends to establish 15 September as an annual celebration of the marathon. The association, which represents 470 marathons and distance races in more than 120 countries, is linking the date to Michel Br\u00e9al\u2019s contribution and has also named him its honorary \u201cFounder Emeritus\u201d. AIMS says this is the first time it has granted the title.<\/p>\n\n\n\n

The 2026 ceremony is scheduled for 14:00-15:00 at Montparnasse. The restoration has been organised jointly by AIMS, ARTMARATHON and the Michel Br\u00e9al Society. The programme includes contributions from Br\u00e9al\u2019s family, historians and representatives of the international marathon movement.<\/p>\n\n\n\n

The scope matters. AIMS is promoting a worldwide commemoration within the distance-running community; its announcement does not present the date as an international day formally proclaimed by the United Nations, the International Olympic Committee or World Athletics. It does not change race rules, calendars or course-certification standards.<\/p>\n\n\n\n

Why 15 September was chosen<\/h2>\n\n\n\n

The date is not the anniversary of the first Olympic marathon. It commemorates a letter dated 15 September 1894, sent by Michel Br\u00e9al to Pierre de Coubertin from Glion, Switzerland, shortly after the Sorbonne congress that had set the modern Olympic revival in motion.<\/p>\n\n\n\n

Br\u00e9al suggested exploring a race from Marathon to the Pnyx in Athens, giving the new event a classical character, and offered to donate a cup for its winner. Coubertin embraced the idea and the Athens 1896 programme included an athletics event called the marathon. Br\u00e9al commissioned and personally paid for the silver trophy awarded to Spyridon Louis, winner of that first Olympic race.<\/p>\n\n\n\n

World Athletics\u2019 historical account<\/a> identifies Br\u00e9al as the linguist and historian who introduced the idea around the 1894 congress. Material preserved in the Olympic library also traces the connection between his proposal, the letter and the cup.<\/p>\n\n\n\n

World Marathon Day therefore marks the documented conception of the modern event, not a supposed date on which Pheidippides ran. That distinction may sound small, but it is central to telling the marathon\u2019s origin accurately.<\/p>\n\n\n\n

The modern marathon was not an ancient Olympic event<\/h2>\n\n\n\n

The popular story begins with the Greek messenger Pheidippides, or Philippides, who is said to have run from the battlefield at Marathon to Athens to announce victory over the Persians before dying. Ancient accounts vary, including versions in which his great journey was between Athens and Sparta. Treating them as a precise report of a 42.195km run compresses legend and later sporting history into one neat but misleading line.<\/p>\n\n\n\n

What is well established is that the marathon as a race began with the first modern Olympic Games. World Athletics says the Athens 1896 event was devised over roughly 40km to celebrate ancient Greece. Spyridon Louis won on 10 April 1896 in the Panathenaic Stadium and turned a new idea into one of the defining stories of the Olympic revival.<\/p>\n\n\n\n

This clarification does not drain the legend of its power. It simply separates three different layers: the tradition of a messenger associated with the Battle of Marathon, Br\u00e9al\u2019s modern proposal in 1894, and the later evolution towards today\u2019s regulated distance.<\/p>\n\n\n\n

From roughly 40km to today\u2019s 42.195km<\/h2>\n\n\n\n

The first Olympic marathon did not cover the distance runners now see on watches and race signs. Early routes varied. At the London 1908 Olympic Games, the race covered 26 miles and 385 yards, or 42.195km, after the start and finish were adjusted around Windsor and the White City Stadium.<\/p>\n\n\n\n

World Athletics\u2019 official discipline history<\/a> dates the standardisation of that measurement to 1921. Put simply, Br\u00e9al\u2019s letter explains why the race exists; London 1908 helps explain why it is that long; and 1921 marks the distance becoming the standard.<\/p>\n\n\n\n
