The bottom line

The Khon Kaen International Marathon's 22nd edition carries genuine multi-decade continuity, in a city with real scale and infrastructure: Thailand's fourth-largest city, one of Isaan's 'big four' regional hubs alongside Udon Thani, Nakhon Ratchasima and Ubon Ratchathani. Khon Kaen is the commercial and political centre of Northeastern Thailand, home to Khon Kaen University, the region's largest, and known internationally for high-quality silk production. Three distances (11.55K/21.1K/42.195K).

22 Years of History

The 2027 race marks the 22nd edition of the Khon Kaen International Marathon, offering three distances: 11.55K, 21.1K and the 42.195K full marathon. ^[1] Registration is currently open. That multi-decade track record puts it among the more established races covered in this research batch, alongside the 37-year Bangkok Marathon and 33-year Pattaya Marathon.

One of Isaan's 'Big Four' Cities

Khon Kaen is the capital of Khon Kaen province and Thailand's fourth-largest city, one of the 'big four' major cities of Isaan (Northeast Thailand) alongside Udon Thani, Nakhon Ratchasima and Ubon Ratchathani. ^[2] With an urban population of nearly 417,000 as of 2024, it's the commercial and political centre of the entire northeastern region -- genuinely major-city infrastructure for race logistics.

Known for Silk and Education

Khon Kaen is internationally known for the high-quality silk produced in the province, and hosts Khon Kaen University, the largest university in Northeastern Thailand and a major regional centre of education and technology. ^[2] That combination of commerce, culture and education gives race weekend genuine destination appeal beyond the run itself.

An Unusual 11.55K Category

Alongside the standard half and full marathon, this race offers an oddly specific 11.55K distance rather than a round 10K -- a genuine quirk among the races covered in this research batch, though the reasoning behind that precise figure isn't documented in available sources. ^[1]

Should You Run It?

If a well-established marathon with genuine multi-decade history in a major regional Thai city appeals, the Khon Kaen International Marathon's 22nd edition on 10 January 2027 is a solid, credible pick.
