By late August the light on Washington Street starts to angle. Race registration emails arrive, City Hall sets out barricades for a festival that has not happened yet, and someone in your group text asks whether Ethnic Expo lands on the same weekend as the marathon this year. It does not, and that is the first useful thing to know.
The second is that the fall of 2026 is a slightly different animal than the last two. The design event that normally organizes the season is quiet this year. Everything else has to carry the calendar, and most of it is walkable from the same downtown blocks.
The Year Exhibit Columbus Sits Out
If you have hosted out of town guests in a recent September, you have probably steered them toward the outdoor installations that spring up around 5th Street and the Cummins headquarters. That is not the assignment in 2026. Exhibit Columbus is marking its tenth year with Fieldwork, a season of grounded work that reflects on a decade of design and public engagement. Following Fieldwork 2026, the next Exhibit Columbus cycle will begin in spring 2027.
Translation for residents: the walkable Miller Prize pavilions are not on the ground this fall. What is on the ground is a program of talks, publications, and convenings, including the inaugural Civic Design Institutes' Prove It Summit, plus a series of winter 2026 events spanning Columbus, Palm Springs, Chicago, and New Harmony that Landmark Columbus Foundation has been staging in the lead up. If your habit has been to build a fall Saturday around the installations, this is the year to build it around something else. There are options.
Six Weekends, One Fridge Magnet
| Weekend | What | Where |
|---|---|---|
| Aug 27–28 | Cabaret at The Commons; Jazz at Helen's | 300 Washington St; 315 Franklin St |
| Sept 12–13 | Columbus Scottish Festival | Bartholomew County Fairgrounds |
| Sept 25–26 | Mill Race Marathon weekend | Start/finish 500 Washington St |
| Sept 25 | Jazz at Helen's | Helen Haddad Hall |
| Oct 9–10 | Ethnic Expo | Columbus City Hall, 123 Washington St |
| Rolling | Fieldwork talks and Prove It Summit | Various downtown venues |
Print that, tape it up, and read on for the parts that are not obvious from a date list.
Marathon Weekend Is A Two-Day Event, Not A Sunday Morning
The Mill Race Marathon is the closest thing Columbus has to a city-wide block party disguised as a race. The 2026 edition runs Friday, September 25 through Saturday, September 26, staged at 500 Washington Street, with the full marathon starting at 7:30 a.m. Saturday. If you are not running, that Friday evening expo and Saturday morning start line still change how downtown moves. Parking around Washington Street tightens. The People Trails through Mill Race Park carry runners in both directions.
The course itself is the reason the race punches above its size. Powered by Cummins, the Marathon course is a flat Boston Qualifier that runs through downtown Columbus taking participants past the architectural sights of the city and through the parks. One number to hold that against: the race ranked 265th largest in 2024, and 6.7 percent of runners qualified for Boston that year, and its Course Score of 99.59 ranks it as the fastest course in Indiana. That is a strange combination — a small field on the state's quickest 26.2 — and it explains why the hotels near I-65 fill up on race weekend even though most of Indiana has never heard of the event.
For residents who are not lacing up, the after party is the point. After the races there is family fun downtown with food, music, and a bungee bouncer, the after party theme is Super Heroes with costumed characters wandering the streets, and it ends at 4:30 p.m. after the drawing for a new truck. Bring the kids. Bring lawn chairs. Then go home before your legs remember they did not train.
The Scottish Festival Is Not A Downtown Event, And That Matters
The other September anchor pulls the crowd east to the fairgrounds. Held at the Bartholomew County Fairgrounds the second weekend in September, the annual Scottish festival brings a Highland tradition to southern Indiana. Expect Celtic concerts, Ceilidh, Highland dancing competition, sporting competitions, clan tents, sheep dog trials, European car show, music, bagpipe marching bands, re-enactors and living history, children's activities, Scottish dancing, merchandise, and food vendors.
A note on planning your Saturday. The fairgrounds are a different logistical world than Washington Street. You will drive. You will park on grass. Kids can run. Dogs generally welcome depending on the venue's posted rules. This is the day of the fall where the festival experience is a proper day trip inside your own county rather than a walk from a downtown parking garage.
Ethnic Expo, And What Japan Means This Year
The largest civic gathering of the fall lands on the second weekend of October. Ethnic Expo runs October 9 and 10, 11 a.m. to 10 p.m. Friday and Saturday. It takes place surrounding Columbus City Hall, located at 123 Washington Street.
Two data points that reframe how you think about this weekend. Organized by the City of Columbus with longtime title sponsor First Financial Bank, it has blossomed into one of the area's largest festivals, drawing 30,000 to 35,000 attendees annually, now approaching its 42nd year in 2026. That is a festival almost half the size of the city's population, held in a two-block radius, every October. If you have wondered why parking downtown feels sideways that weekend, that is the reason.
The rotating host country is the reason to go even if you have gone every year. Japan will host the 38th Annual Ethnic Expo. Japan has been selected to host this year's Ethnic Expo. That informs the featured food booths, the stage programming, and the cultural exhibits on the City Hall lawn. The vendor cycle also tells you when the food lineup firms up: food booth applications are due by August 14, 2026, and notifications go out within 60 days of application submittal or by August 31, 2026. If you have a friend who has been threatening to vend, that is the date to needle them about.
The Music Runs Under All Of It
The stretch between Cabaret and the marathon is when the Columbus Indiana Philharmonic quietly does some of its most interesting programming, and residents miss it because the outdoor stuff is louder. Two nights to hold:
- Cabaret at The Commons with Noah Ricketts, August 27, 2026 at 7:30 p.m., The Commons, 300 Washington Street
- Jazz at Helen's, August 28, 2026 at 7:30 p.m., Helen Haddad Hall, 315 Franklin Street, with Bleu Django
- Jazz at Helen's returns September 25 at 7:30 p.m.
The September 25 date is the same Friday as the marathon expo. A very Columbus evening is possible: pick up your race bib at 500 Washington, walk five blocks to Helen Haddad Hall for jazz, walk home. If the marathon is not your project, the same night is one of the best low-key concert bookings the fall offers.
What A Local Does With All Of This
The pattern to see is this. In an ordinary fall, Exhibit Columbus supplies the connective tissue between weekends. This year it does not, and the calendar reveals what has been carrying the season the whole time: a Boston-qualifying race that a global engine company underwrites, a festival at the fairgrounds that is older than most residents realize, a City Hall block party in its fifth decade, and a chamber-music season that treats a converted downtown hall like a jazz club.
If you had to reduce the fall to three weekends, they are September 12 for the fairgrounds, September 26 for the marathon after party, and October 10 for the Japan-hosted Ethnic Expo. If you want the sleeper pick, it is the September 25 Jazz at Helen's, because half the town will be at a pasta dinner or an expo booth and the room will feel like a secret.
One more note for hosts. Out of town family will ask about Exhibit Columbus this year. The answer is that the program was born from a 1986 exhibition, Good Design and the Community: Columbus, Indiana, and J. Irwin Miller argued that "Architecture is something you can see. You cannot see a spirit or a temperament or a character, though, and there's an invisible part of this community of which I am very proud." Fieldwork is the invisible part. The visible part comes back in spring 2027.
If you own a home here and you have been thinking about what your next move looks like on the calendar side of things, the fall is a good time to compare notes. To talk about the local market or plan a private tour of a Grandview Lake or Columbus-area property, reach out to Christopher Braun at Grandview Lake Property to schedule a private tour or consultation.
