THEY were aiming to complete their first triathlon relay together - as colleagues and as friends.
But their Sunday afternoon at East Coast Park ended in tragedy, when one of them died suddenly after taking part in the swimming leg of the Osim Singapore International Triathlon.
Calvin Lee Wee Sing, 42, was pronounced dead at 2.45pm on Sunday, about one and a half hours after he ran into trouble during the swim segment of the Mix/Open relay race at the annual triathlon event.
Mr Lee appeared to be struggling and disoriented in the water, about 350 metres away from the finish line of the 1.5km swim race.
He was spotted by a life marshal, who quickly called for a jet ski to bring the stricken swimmer to shore.
Paramedics and doctors tried unsuccessfully to revive Mr Lee - who was by then unconscious and foaming in the mouth - using cardiopulmonary resuscitation or CPR.
Attempts to jumpstart his heart using an automated external defibrillator (AED) also failed. He died later at Changi General Hospital.
Organisers say the cause of death is still under investigation.
Mr Lee - the chief executive officer of Deutsche Telekom Asia - is the latest fit and active person to die suddenly while exercising strenuously.
