Korat Marathon: Dates, Tickets & Venue (Nakhon Ratchasima)

A November Sunday on the edge of Isan

Korat is where central Thailand turns into the northeast. Nakhon Ratchasima is the largest city of Isan by population, and it works as the region’s front door. Highway 2, the Mittraphap Road, runs up from Bangkok here before continuing north toward Khon Kaen and the Mekong.

The Korat Marathon takes place on Sunday, November 8, 2026. It falls inside Thailand’s busy fourth-quarter running season, when the rains have mostly cleared and the cool season begins. Dawn temperatures are kinder than at any other point in the year. Midday sun still counts, though, which is why Thai road races run in the dark hours before and around sunrise.

Four distances, one start town

The race offers four distances, so a mixed group can travel together:

• Marathon (42.195km): the full distance, for runners with a season of training behind them
• Half marathon (21.1km): the most common choice for travelling runners on Thailand’s Q4 circuit
• 10km: a solid road race for regular runners
• 5km: often a fun-run crowd, families and first-timers

Because it sits in the same weeks as many other Thai road races, plenty of runners treat Korat as one stop in a run of autumn events. The flat ground of the Khorat Plateau around the city also suits a steady pace more than hill training does.

Getting to Nakhon Ratchasima

Bangkok is the usual starting point for international visitors. There are three practical ways up:

• Train: State Railway of Thailand services on the Northeastern Line stop at Nakhon Ratchasima station, close to the city centre.
• Bus: Coaches run from Bangkok’s Mo Chit (Northern and Northeastern) Bus Terminal to Korat’s bus terminals. It is one of the most frequent intercity routes in the country.
• Car: Highway 2 runs the whole way, passing the turn-offs for Khao Yai National Park around Pak Chong.

The drive takes most of a morning, depending on Bangkok traffic. Travelling runners commonly reach Korat on the Saturday, which also lines up with race-kit collection at Thai events.

Bib pickup, dawn starts and the Thai race-day routine

Thai road races follow a familiar rhythm, and Korat sits inside it. Bib and kit collection usually happens at an expo on the day or days before the race. Runners bring the ID they registered with, plus the registration confirmation on their phone.

On race morning, the start area fills in the dark. Start times at Thai marathons are set well before sunrise so the long-distance field finishes before the heat builds. Shorter distances usually go off later in sequence. Locals call these events ngan wing (งานวิ่ง), “running events”, and the start pens tend to fill with club runners in matching shirts.

A few customs that help:

• Paying: food stalls and street vendors take cash or a PromptPay QR scan; cards are less common away from malls.
• Thank-yous: a wai and “khop khun khrap/kha” to the volunteers at water stations goes a long way.
• The monument: if your route takes you past Thao Suranari (Ya Mo) Monument, treat it as a shrine. People come to leave flowers and make offerings, so runners don’t climb it for photos.

Where the race is held, and where to sleep

The organiser publishes the start and finish venue, course map and registration details on its official race channels. Those are the source for the exact location of this edition.

The old city sits inside a rectangular moat. Chumphon Gate and the Thao Suranari Monument mark its western side, and most visitors stay in or near that core. Larger hotels also cluster around the Terminal 21 Korat and The Mall Korat shopping centres along Mittraphap Road. A short tuk-tuk, songthaew or ride-hail trip links the two areas. Runners usually choose a bed within easy reach of the start, since public transport isn’t running at pre-dawn race hours.

After the finish: noodles and Khmer ruins

Recovery food is easy here. Pad mee Korat, the city’s own stir-fried rice noodles, has a sweet-sour sauce and is sold at stalls and shophouse restaurants across town. Isan staples such as som tam (papaya salad), grilled chicken and sticky rice are everywhere too.

With a spare day, two big trips sit within reach:

• Phimai Historical Park: roughly 60km northeast, with one of Thailand’s most important Khmer temple complexes. It predates Angkor Wat and shares its design language.
• Khao Yai National Park: to the southwest near Pak Chong, a UNESCO-listed forest with waterfalls and wildlife. It makes a natural stop on the road back to Bangkok.

Easy walking around the moat and a slow bowl of noodles near Ya Mo also suit legs that have just covered 42km.
