River Kwai International Half Marathon Ahotu 78a7d5faf90fc867e51f

September 10, 2017

The River Kwai Half Marathon is the oldest road race in Thailand.

The out and back course is one of the most scenic in Thailand. It takes runners up a gradual climb to the turn around point at 10.5 km. The declining return leg to the finish line will make for a fast second half of the race and most runners normally post a negative split at this race. There is also a 10K Run on offer which uses the same course with an earlier turn around point.

Race Distance
Ultra Half Marathon 05:30 35.000 km
