Television producer Lim Nghee Huat will run in the Badwater Ultramarathon in the United States from July 21 to 23 to raise funds for St Hilda's Community Services Centre.
This is the second time the 61-year-old father of three is taking part in the ultramarathon in California.
Last year, he raised $130,000 for the Heartware Network, a Singapore charity which works with youth, after running 217km in California's Death Valley National Park.
Mr Lim ran his first ultramarathon - which involves distances longer than the usual marathon distance of 42km - nine years ago.
