The Top 10 Most Popular Marathon Races In The World 2026:

1. TCS New York City Marathon

The TCS New York City Marathon stands alone as the world's largest marathon, shattering records in 2025 when 59,000+ runners crossed the finish line in Central Park. The race draws participants from approximately 130 countries, creating an international spectacle that no other marathon can match. With over 1.7 million spectators lining the 26.2-mile course through all five boroughs, the energy level remains unmatched from the starting cannon on the Verrazzano-Narrows Bridge to the final stretch through Manhattan.

The 2026 race holds special significance as it marks the 50th anniversary of the iconic five-borough format. Runners begin on Staten Island, traverse through Brooklyn's brownstone neighborhoods, push through Queens and the Bronx, before the triumphant finish in Central Park. The course elevation changes are moderate but significant, with the Queensboro Bridge climb at mile 15 often marking a turning point in race strategy.

First-time marathoners and seasoned runners alike cite the New York crowds as the most energizing in the world, with spectators holding creative signs, offering high-fives, and creating noise levels that drown out fatigue.

2. TCS London Marathon

Founded in 1981, the TCS London Marathon has evolved into one of the world's most prestigious races with 43,000+ starters and finishers annually. The race broadcasts to over 196 countries and draws between four and five million UK television viewers, cementing its status as a cultural phenomenon beyond just athletics. The course begins in Greenwich Park and follows a scenic route through London's historic heart before finishing on The Mall in front of Buckingham Palace, offering runners an experience that few races can rival.

London's mostly flat course makes it ideal for first-time marathoners and those chasing personal bests. The route passes Tower Bridge, Canary Wharf, and Big Ben, giving runners postcard-perfect views at nearly every turn. What sets London apart is its inclusive philosophy - the race enforces no cut-off time, welcoming charity runners who may take seven hours alongside elite athletes finishing in under two hours and ten minutes. This democratic approach has made it the most accessible World Marathon Major while maintaining its competitive edge with a world-class elite field.

The crowd support in London ranks among the best globally, with spectators packing sidewalks from start to finish. The British tradition of costume running adds color to the event, with thousands tackling the distance dressed as everything from rhinos to telephone boxes, raising millions for charity. The race's charitable impact exceeds that of any other single-day fundraising event worldwide, with runners collectively raising over £66 million annually for thousands of causes.

3. Boston Marathon

The Boston Marathon carries more history than any other race on earth. Founded in 1897 and inspired by the first modern Olympic marathon the year before, Boston celebrates its 130th anniversary on April 20, 2026. Organized by the Boston Athletic Association, this race stands apart through its qualifying standards - every runner must earn their spot by hitting time targets in a certified marathon, making it the most selective major marathon in the world.

The 2026 edition includes special tributes to Bobbi Gibb, who unofficially ran the course in 1966, six years before women gained official entry. The race also commemorates the infamous 1976 "Run for the Hoses" when temperatures hit 96°F and volunteers sprayed runners with garden hoses in a desperate attempt to prevent heat casualties. These historical moments reflect Boston's role as more than a race - it's a living archive of marathon running's evolution.

The course itself presents significant challenges, particularly Heartbreak Hill between miles 20 and 21, where the Newton hills test even the most prepared runners. The point-to-point course runs from Hopkinton to Boston's Back Bay, following Route 135 through eight Massachusetts towns. What makes Boston special isn't just the difficulty or the history - it's the knowledge that everyone around you qualified, creating a field of proven marathoners all chasing excellence. The race represents the ultimate benchmark in distance running, where simply crossing the finish line carries prestige that transcends finishing time.

4. Tokyo Marathon

No other mass marathon in Japan combines Tokyo's unique blend of elite competition and massive participation, drawing 30,000-40,000 runners annually to experience Japanese efficiency and enthusiasm. The race delivers exceptional organization that runners consistently praise as the best in the world, with aid stations stocked precisely, volunteers positioned at every turn, and logistics that run like clockwork. The course weaves through vibrant neon-lit districts, past historic shrines, and along modern boulevards, creating a visual experience unlike any Western marathon.

Tokyo's reputation as a fast course gained further validation in 2026 when Tadese Takele won in 2:03:37, with multiple runners breaking 2:04:00. The course record stands at 2:03:23, placing it among the fastest certified marathons globally. The flat terrain and cool late-winter temperatures create ideal conditions for record attempts, attracting elite athletes seeking to qualify for championship events or break national records.

5. BMW Berlin Marathon

Berlin owns the title of world's fastest marathon course, where Eliud Kipchoge demolished his own world record in 2022 with a stunning 2:01:09 performance. That run shaved 30 seconds off the mark he had set on the same course in 2018, cementing Berlin's reputation as the place where records fall. The September 27, 2026 race will attract elite runners chasing similar glory along with 40,000+ participants seeking personal bests on Germany's legendary flat terrain.

The course's speed comes from its minimal elevation changes and wide, smooth roads that allow runners to maintain consistent pacing. The route tours Germany's capital through iconic locations including the Brandenburg Gate, with straightaways that stretch for kilometers without significant turns. German organizational precision ensures perfect aid station placement, accurate distance markers, and crowd control that keeps the course clear for fast running.

Berlin's status as an Abbott World Marathon Major guarantees a competitive field, but the race welcomes runners of all abilities who appreciate the course's forgiving nature. The fall timing provides cool temperatures ideal for marathon running, typically between 50-60°F at the start. The finish at the Brandenburg Gate delivers an emotional conclusion, with runners passing through one of Europe's most recognizable landmarks. For athletes seeking to break three hours, qualify for Boston, or simply run their fastest possible time, Berlin offers the best chance of success.

6. Bank of America Chicago Marathon

Chicago's flat, fast course attracted 54,351 finishers in 2025, making it one of the largest marathons in the United States. The October 11, 2026 race will draw more than 1.7 million spectators to the streets, creating support levels that rival New York and London. The course sweeps through 29 different Chicago neighborhoods, offering runners a comprehensive tour of the city from Grant Park through ethnic enclaves, historic districts, and modern developments before returning to the start.

The point-A-to-point-A route design means runners cover an out-and-back loop, allowing them to see the lead pack heading in the opposite direction around the halfway point. This unique feature creates motivation as recreational runners can witness elite athletes in full flight. The course's flatness has produced two marathon world records historically, and it remains among the fastest certified courses globally. Boston qualifiers flock to Chicago for its reputation as a PR-friendly race where conditions typically cooperate.

Chicago's popularity has surged in recent years, with acceptance rates dropping to 2-5% as demand outstrips the race's capacity. The autumn timing provides ideal temperatures, usually in the 40s and 50s at the start, with comfortable conditions lasting through the finish. The race's growing prestige has elevated it within the World Marathon Majors, and many runners now consider it equal to the older, more established races. The Midwest hospitality translates to enthusiastic crowds who create noise levels that carry runners through the difficult late miles.

7. Schneider Electric Marathon de Paris

The Schneider Electric Marathon de Paris ranks as one of Europe's largest marathons with 50,000+ participants flooding the French capital each spring. Scheduled for April 12, 2026, the race has become notoriously difficult to enter with acceptance rates of just 2-5%, reflecting massive international demand. The course record stands at 2:05:25, established during competitive racing in 2026 that featured 2,000-3,000 elite runners chasing fast times and championship qualification.

The route delivers everything runners expect from Paris - sweeping views of the Champs-Élysées, runs along the Seine, and passages through historic arrondissements that showcase French architecture and culture. The course begins on the Champs-Élysées near the Arc de Triomphe before touring through both banks of the Seine and finishing back at the famous avenue. The relatively flat profile makes it suitable for first-time marathoners, though the cobblestones in some sections require careful footing.

Paris offers a distinctly European marathon experience with enthusiastic but more reserved crowds compared to American races, and aid stations stocked with French sensibilities including wine at later stations. The spring timing means unpredictable weather ranging from cool rain to warm sunshine, requiring runners to prepare for various conditions. The race's combination of massive participation, elite competition, and unmatched Parisian scenery has made it one of the most sought-after destination marathons in Europe, with runners returning repeatedly to experience the unique atmosphere.

8. TCS Sydney Marathon

The TCS Sydney Marathon made history by becoming the newest member of the Abbott World Marathon Majors, officially inducted in November 2024 after years as a candidate race. The August 30, 2026 race marks its first full season as part of the prestigious six-race series, elevating Sydney's profile dramatically. Marathon legend Eliud Kipchoge praised the course after running it, stating: "This is a beautiful and unique course. The beauty was about the crowd, the way people cheered on the way, at the beginning, at the finishing line, it was wonderful."

Sydney attracts approximately 12,000+ participants, notably smaller than European and American majors, creating a more intimate racing experience without the massive crowds that can slow larger marathons. The course delivers stunning views of Sydney Harbour, the Opera House, and the Harbour Bridge, showcasing Australia's most iconic city from a runner's perspective. The route crosses the Harbour Bridge, offering panoramic views that runners cite as unforgettable highlights worth the months of training.

The 6-hour cut-off time accommodates runners of varying abilities, though the course presents challenges including the bridge climb and undulating terrain through Sydney's harbor-side neighborhoods.

Sydney's addition to the World Marathon Majors creates opportunities for Southern Hemisphere runners to pursue Six Star status without extensive international travel, while also attracting Northern Hemisphere runners seeking a winter racing destination.

9. TCS Amsterdam Marathon

The TCS Amsterdam Marathon scheduled for October 17-18, 2026 has established itself as one of Europe's premier autumn marathons through its combination of flat terrain, scenic canals, and excellent organization. The multi-day event format includes the full marathon, Mizuno Half Marathon, 7.5K, Good Morning City Run, Kids Run, and Heroes Run, creating a festival atmosphere that extends beyond the main race. The course winds through Amsterdam's historic canals, past 17th-century architecture, and along tree-lined streets that showcase Dutch urban planning.

Amsterdam ranks consistently among the top 10 best marathons globally according to runner surveys and expert rankings, praised for its pancake-flat course that's ideal for personal record attempts. The gentle terrain allows runners to maintain even pacing without the energy-sapping hills that plague other European courses.

The festive atmosphere captures Amsterdam's cycling and running culture, with locals turning out in large numbers to support runners despite the relatively modest field size.

The spectators create a party atmosphere with live music at various points, pub patrons spilling onto sidewalks to cheer, and the legendary Irish hospitality that makes runners feel welcomed.

Dublin serves as an excellent destination race for international runners seeking to combine athletics with Irish culture, food, and pub traditions. The relatively smaller field size compared to London or Paris means less congestion at the start and throughout the course, allowing runners to settle into their pace quickly. The race's strong European presence and growing international reputation have elevated it beyond regional status, attracting serious marathoners who appreciate the combination of competitive racing and cultural experience. The post-race celebrations in Dublin's Temple Bar district provide memorable recovery, with runners swapping stories over pints of Guinness.
