From the modern race’s invention in the 1890s to the ratified sub-two-hour men’s marathon in 2026: Olympic champions, women’s fight for inclusion, wheelchair racing, the city-marathon boom, record progression, technology and the culture of finishing. **How to explore.** Chapter headings and illustrated era bands organize the story. Hover over a small cluster to fan out its moments; open an entry for its notes, references and media credit. Tags let you follow women, Olympics, records, races, wheelchair competition, culture or integrity. Relationship arcs connect selected precedents, performances and institutions; an arc denotes historical connection or sequence, not proof of causation. **Scope and dates.** The plotted chronology begins in 1894, when Michel Bréal proposed the modern race.

Coverage is selective and global, with research checked through 27 October 2026; recent results do not imply exhaustive coverage of every race. **Reading records carefully.** Pre-2004 road marks are generally described as world bests. Official world records require eligible courses and competition conditions. Women-only records are distinguished from overall women’s records achieved in mixed races. Kipchoge’s assisted sub-two-hour exhibition in 2019 is distinguished from Sawe’s eligible 1:59:30 in London in 2026. Wheelchair performances belong to their own divisions and classifications. Disputed early marks and the scope of anti-doping decisions are identified in the notes. **Sources and media.** Summaries are original and each entry links supporting references. Historical coverage uses event and athlete articles alongside World Athletics, race organizers, the International Paralympic Committee a…
