Chris Perkin will never recover from losing his wife and newborn within a week.
But he is hoping his fundraising through the Sunshine Beach Run gives other parents who suffer the loss of a child through SIDS the support they need.
"The run is a pretty tearful sort of a day but it can also be a joyful day," Mr Perkin, 38, said.
The West Coast Eagles physiotherapist lost his son Jake who was stillborn three years ago, and his wife Cindy died shortly after the birth.
As a tribute to both, he helped launch the run, now in its second year, which raises money for SIDS and Kids - a not-for-profit research group that also gives support to families who lose a child through miscarriage, stillbirth or sudden infant death syndrome.
"I wanted to help prevent this and prevent other people having to go through something similar," he said.
The event, a 1km, 3km or 5km walk or run at City Beach, raised almost $100,000 this year and he hopes to top that at the next run early next year.
West Coast midfielder Matt Priddis, whose first child Nala was born four weeks ago, said he felt for people who went through such a tragedy - especially after the birth of his daughter.
"When you first come home from the hospital, every noise you hear from the cot you're up pretty quick," he said.
SIDS and Kids chief executive Shauna Gaebler said 200 families had a stillbirth and about 20 babies died from preventable causes in their sleep in WA each year.
The run is on February 10 and is open to everyone.More details are available at sunshinebeachrun.com.au
