Best Fall Marathons (September–November)
The ultimate guide to fall marathon racing — the peak season with 174 races worldwide. Discover the best September, October, and November marathons with weather data, course profiles, and travel tips.
Table of Contents
Fall is marathon season. In our database of 500 races worldwide, 174 take place between September and November — more than any other three-month window. October alone hosts 99 races. There’s a reason for this concentration: the physics of marathon running favors cool, stable weather, and the autumn months deliver exactly that across the Northern Hemisphere.
If you’re training through summer with a fall goal race, you’re in good company. The question isn’t whether to run a fall marathon — it’s which one. This guide breaks down the best options by month and continent, with the data to help you choose.
Why Fall Is Peak Marathon Season
The ideal marathon temperature is 7–15°C (45–59°F). Above that range, performance degrades measurably — studies show a 1–2% slowdown for every 5°C above 15°C. Fall delivers those ideal conditions across most of the world’s major marathon cities.
There’s a training advantage, too. A fall marathon means building your base through spring, hitting peak mileage in summer, and tapering as the weather cools. Yes, summer long runs are brutal — but they build heat adaptation that pays dividends when race day arrives 10–15 degrees cooler than your hardest training run.
The calendar also works socially. A late September or October marathon leaves room for a spring tune-up half and a summer of focused training, then frees you for the holiday season with fitness banked and a medal earned.
September: The Season Opener
September hosts 36 races in our database. The month sits at the transition between summer and autumn — early September races in warmer climates can still face heat, while late September events in Northern Europe hit ideal conditions.
Berlin Marathon — The World Record Course
The Berlin Marathon is the crown jewel of fall racing and arguably the world’s premier marathon. Held in late September, it draws 45,000 finishers from 150 countries on a relentlessly flat course through the German capital. The finish through the Brandenburg Gate is iconic, and the course has produced more world records than any other — including Eliud Kipchoge’s 2:01:09 in 2022.
September in Berlin averages 12–18°C with low humidity. The combination of flat terrain, cool weather, and an elite-level organizational machine makes this the race to beat if your goal is a personal best.

| International | 60% |
| Avg finish | 4:18:00 |
| Course record | 2:01:09 (Kipchoge, 2022) |
| Established | 1974 |
The case for Berlin: You want the fastest possible time. You want a world-class city break. You want to run where marathon history is made. Registration opens early and sells out — plan 6+ months ahead.
Other September Picks
Beyond Berlin, September offers strong options worldwide. Look for races in Northern Europe and Canada where the heat has broken but winter hasn’t arrived. The month is ideal for runners who trained through a Northern Hemisphere summer and want to race before October’s packed calendar.
October: The Main Event
October is the heart of fall marathon season with a staggering 99 races in our database. Nearly every major marathon city hosts a race this month, and the weather across the Northern Hemisphere is at its running-weather best.
Chicago Marathon — The Windy City Classic
The Chicago Marathon is the largest fall marathon in North America, drawing 42,000 finishers through a flat loop that touches 29 neighborhoods. Established in 1977, it’s one of the six Abbott World Marathon Majors, with a fast course and a famously enthusiastic crowd.
October in Chicago averages 8–16°C — a dramatic improvement over the city’s hot summers. The course is a tour of Chicago’s diversity, from the high-rises of the Loop to Pilsen, Chinatown, and the Magnificent Mile. If you’re chasing a Boston qualifier, Chicago’s flat profile and cool conditions make it one of the best options in North America.

The case for Chicago: Fast course, incredible crowd support, world-class food city. Deep-dish pizza has never tasted better than after 26.2 miles.
Amsterdam Marathon — Europe’s Speed Secret
The Amsterdam Marathon is one of the fastest races in Europe that isn’t Berlin. The October event draws 17,500 finishers on a dead-flat course that starts and finishes at the 1928 Olympic Stadium. The route along the Amstel River and through the polders is at literal sea level — you cannot find flatter terrain.
At 65% international participation, it’s a true destination race. October temperatures of 8–14°C and the course’s proven speed (record: 2:05:48) make it an excellent PR opportunity.

Toronto Waterfront Marathon — Canada’s Fall Classic
The Toronto Waterfront Marathon runs along Lake Ontario’s shoreline, drawing 8,500 finishers on an easy, flat course. Established in 2009, it’s a relatively young race that has quickly built a reputation for strong organization and fast times.
October in Toronto hits the sweet spot — summer’s humidity is gone, and the fall colors along the waterfront are spectacular. The lakeside course offers consistent conditions with minimal wind.

Frankfurt Marathon — German Precision, Part Two
The Frankfurt Marathon proves that Germany knows how to host a marathon. The October race draws 10,200 finishers on a flat course through the financial capital. It’s less famous than Berlin, but that’s an advantage — easier to enter, less crowded, and equally well-organized.

The case for Frankfurt: If Berlin sold out, Frankfurt is the plan B that might actually be plan A. Cheaper flights (Frankfurt is Europe’s biggest hub), cheaper hotels, and a course that’s just as fast.
Dublin Marathon — Ireland’s Big Day
The Dublin Marathon draws 17,500 finishers through Ireland’s capital each October. The flat, easy course loops through Phoenix Park and Georgian streetscapes, with crowd support that’s famously enthusiastic — Dublin takes its marathon personally.

Detroit Marathon — The International Border Crossing
The Detroit Marathon is unique: you cross the Ambassador Bridge into Canada and return through the underwater Windsor Tunnel — the only marathon that takes you across an international border. The October race draws 25,000 finishers on an easy, flat course.

November: The Closers
November hosts 39 races in our database. As autumn deepens, the window for ideal conditions narrows — but two iconic races anchor the month.
New York City Marathon — The Big One
The New York City Marathon is the world’s largest marathon, drawing 51,000 finishers across all five boroughs. The first-Sunday-in-November tradition has been running since 1970, making it one of the most established races on earth.
The course is rated moderate difficulty — the bridges create genuine elevation changes, and the profile is far from flat. But nobody runs New York for a fast time. You run it for the experience: starting on Staten Island, crossing the Verrazzano-Narrows Bridge, running through Brooklyn, Queens, the Bronx, and finishing in Central Park to roaring crowds.
| Stat | Value |
|---|---|
| Finishers | 51,000 |

The case for New York: This is the marathon on every runner’s bucket list. Entry is by lottery (roughly 15% acceptance) or through qualifying times, charity entries, or international tour operators. November temperatures of 5–12°C are usually ideal, though conditions vary. The city on marathon Sunday is electric.
Athens Marathon — The Original
The Athens Marathon runs the route that gave the marathon its name. The November course follows in the footsteps of Pheidippides from Marathon to Athens, finishing in the 1896 Panathenaic Stadium. This is a pilgrimage, not a PR attempt — the first half climbs steadily uphill before a dramatic descent into the city.
The race draws 18,500 finishers from 127 countries. November in Athens averages 12–18°C — warm by Northern European standards, cool enough for the hilly course.
| Stat | Value |
|---|---|
| Finishers | 18,500 |
| International | 48% |
| Avg finish | 4:28:00 |
| Course record | 2:10:21 |
| DNF rate | 8% |
The case for Athens: The 8% DNF rate tells you this course demands respect. But finishing in that marble stadium — where the first modern Olympic marathon ended — is worth every uphill mile. Athens in November is affordable, uncrowded, and steeped in history. For more on this race, see our European marathon guide.

Fall Marathon Training Considerations
Training for a fall marathon means running your highest-mileage weeks in the heat of summer. A few practical tips:
- Start early — Begin your training cycle 16–20 weeks before race day, which means May or June for an October race. See our 16-week training plan for a structured approach.
- Embrace heat training — Summer long runs in heat build physiological adaptations that pay off on a cool race day. Run early (before 7 AM) and carry water.
- Adjust expectations — Your summer training paces will be 15–30 seconds per mile slower than your fall race pace. Don’t panic. The fitness is there; the heat is masking it.
- Taper wisely — Most fall marathons are in October, which means tapering starts in late September as temperatures drop. Your easy runs will suddenly feel effortless — that’s the point.
- Race day gear — Pack for the conditions. Fall mornings are cold (5–10°C at the start), but you’ll warm up quickly. Wear disposable layers at the start and plan your race day checklist accordingly.
The Bottom Line
Fall marathon season offers an embarrassment of riches. From September’s opener in Berlin through November’s closers in New York and Athens, these months concentrate the world’s best racing conditions, most iconic courses, and largest fields into a 12-week window.
Pick the race that matches your goal — speed, experience, travel, or bucket list — and commit. The training will be hard. The summer miles will be sweaty. But that October or November morning, standing at the start line in crisp autumn air with thousands of other runners, you’ll know exactly why fall is marathon season.
