Adam Selwood’s campaign to raise money for mental health received a groundswell of donations on the day of his death, just a week before he was supposed to complete a charity fun run.

Selwood died on Saturday just months after the death of his twin brother — former Brisbane footballer Troy.

As part of a tribute to his brother, Selwood was set to take part in the HBF Run for a Reason next Sunday, raising money for charity zero2hero which “provide programs that educate, engage and empower young people to support and maintain their own mental health and prevent suicide in the community”.

Selwood’s goal was to raise $10,000 and after news of his passing broke, fans and football supporters began to pour in as part of a tribute to the 2006 premiership player.

The Eagles premiership player had already raised more than $21,000, but that number climbed towards $22,000 late on Saturday.

Many of those donations were worth more than $100.

“Following the heartbreaking loss of my twin brother to suicide, I have made the decision to take on the HBF Run for a Reason Half Marathon,” Selwood wrote on the donation page.

“My goal is to raise $10,000 in support of Zero2Hero — an incredible charity committed to educating, engaging, and empowering young people to become mental health leaders and help prevent youth suicide here in Western Australia.

“This cause is deeply personal to me, and this run marks an important step in my own healing journey, as well as an ongoing commitment to raising awareness about mental health and suicide prevention across the country.

“Your support would mean the world to me. Every donation, no matter the amount, makes a real and lasting difference in the lives of young Western Australians and is deeply appreciated by myself, my family, and the Zero2Hero community.

“Thank you, from the bottom of my heart, for your love, generosity, and support in recent times. I will be sharing my training journey in the lead-up to the run on Sunday, 25 May, and I am incredibly grateful to those who have already helped me get the runners back on and start moving again.”

Only a month ago, Selwood again posted thanking people for their donations and raising the goal to $18,000.

“It is truly amazing, and I know Troy would be proud of the impact we are making together,” he wrote.

“Thank you also to the friends who have been joining me on training runs. My fitness is strong, my weight is back to playing days, and I clocked just under 15kms this morning.

“I feel so fortunate to be surrounded by such wonderful people as I prepare for the event in late May.”
