SINGAPORE - SEA Games champion Soh Rui Yong clocked 2hr 37min 33sec at the London Marathon on Sunday, placing 211st overall at the event.

His timing fell short of the Olympic qualifying mark of 2:19, and is also off his personal best of 2:26:01 clocked on his debut at the California International Marathon in 2014.

The 24-year-old, carrying a plantar fasciitis injury in his left foot, had clocked a season-best at the World Half Marathon Championships in Cardiff last month, finishing in 1:06:56.

He aggravated his injury at the event but chose to run through the pain in London in the hopes of becoming the first Singaporean to qualify for the Olympics in the marathon.

Team-mate Mok Ying Ren, who won the 2013 SEA Games gold, is also gunning for the Rio Games.

The Olympic qualifying window is opened until July.
