The bottom line
The RSAWIT International Marathon takes place at Sibu Town Square in Sarawak — Malaysian Borneo's third-largest city, known for its Foochow Chinese heritage and as the gateway to the Rajang River. Two distances (42K, 21K) with registration open. Sibu is flat, built on the Rajang floodplain, which means a fast course profile — though November humidity on Borneo's coast is always a factor. For runners wanting a Sarawak marathon outside the Kuching mainstream, this is a bookable option.
Sibu: Sarawak's Riverside Hub
Sibu is a working river-port city on the Rajang — Sarawak's longest river — with a distinctive Foochow Chinese cultural identity. [1] Sibu Town Square provides a central, accessible start/finish precinct in a city that's predominantly flat. November is the onset of Sarawak's landas (monsoon) season, with higher rainfall probability.
