Runners who stop for a refreshing drink at this weekend's HBF Run for a Reason could be forgiven for thinking they are seeing triple.
Wembley Downs triplets Adam, Brent and Calvin Zaltsman, 15, have signed on to volunteer at the event, which has already attracted a record 18,000 participants.
Along with their mother Debbie Zaltsman, the teenagers will be manning one of the aid stations on Sunday.
Ms Zaltsman said the fraternal triplets had decided to volunteer to contribute towards the hours of community service they were required to do for their school, Newman College.
"I always try to get them to do as much as they can," Ms Zaltsman said. "They are qualified lifesavers and I think they need to be taught to give back."
"I've tried to drum that into them because they are all very sporty and I've said, 'If nobody ever volunteered you wouldn't have your sports, you wouldn't have anything, because it's all based on volunteers'."
Ms Zaltsman said close friends had suffered breast cancer and other diseases, making the family's decision to support the event an easy one.
The HBF Run for a Reason has already raised more than $500,000 for the Heart Foundation WA, Cancer Council WA, Diabetes WA and Lifeline WA.To find out more about the run or to sponsor someone taking part, visit www.hbf.com.au .
