SINGAPORE, June 7 (Reuters) - As a marathon runner with ambitions of winning the gold medal at the Southeast Asian Games, Soh Rui Yong spent months preparing himself to combat Singapore's stifling humidity.

Despite hailing from Singapore, Soh currently lives and studies in the United States, often training in snow, so was worried about how he would cope with the notoriously tough conditions back in his home city.

The 23-year-old returned home early to try and acclimatise but when Sunday's marathon started around dawn, he suddenly had to face an altogether new weather problem: a tropical storm.

Located near the equator, Singapore is not only one of the world's most humid cities, it's also one of the wettest so the 12 runners set off on their 42.195 kilometres (26 miles and 385 yards) journey in driving rain.

The downpour made the conditions cooler but it was still tough going on the slippery roads. Ten of the 12 starters finished the long journey, which ended in a sprint finish.
