After 15 hours of taking part in a non-stop relay yesterday, runners still found the energy to take part in a mass dance workout.

More than 6,500 people joined the Singapore Cancer Society-TalkMed Relay for Life which began on Saturday night at the National Stadium and ended there yesterday morning. They raised more than $830,000 for the fight against cancer.

The runners split into teams - ranging in number from two to 100 members - which were required to have at least one runner on the stadium track at all times to symbolise how the fight against cancer never stops.

Around 50 people even chose to complete the 15-hour event alone.

President Halimah Yacob joined in for one lap with cancer survivors.

Participants also lit candles and observed a minute of silence for loved ones lost to the disease.

Speaker of Parliament Tan Chuan-Jin turned up yesterday morning to run the final few laps.

Mr Foo Hee Jug, who chaired the event's organising committee, said: "Relay for Life is not just an event, it is a worldwide movement to bring the community together in the fight against cancer.

"The Singapore community came together with the single purpose of fighting cancer, giving much hope and inspiration to cancer patients, survivors, and caregivers."

Relay for Life began in the United States in 1985. This is the second year that the Singapore Cancer Society has taken part.
