Preston's legacy lives on

It was the easiest decision in a heartbreaking year for the family of teenager Preston Bridge and one which gave six people a second chance at life.

Rod Bridge said when medical staff gave the devastating news that his 16-year-old son would not recover from a hotel balcony fall, the family had "no doubts" about donating his organs.

A year after Preston's death, Mr Bridge said the family takes comfort in learning their decision helped six people on transplant lists. He believes one was a 52-year-old Perth woman who received his son's heart and recovered well from the transplant two days after Preston's life support system was switched off on February 18.

Another recipient is understood to be a young boy.

"It's overwhelming that Preston's still out there and he's given someone an opportunity to have a full life," Mr Bridge said.

Mr Bridge, daughter Aimee and some of Preston's friends have formed a team for the HBF Run for a Reason because 40 per cent of Australian families decline to make organ donations.

The team will race for Donor Mate, a charity set up by transplant recipients to raise awareness of organ donation.
