Aussie radio presenter Carrie Bickmore has paid tribute to Scott Selwood after the former footy star completed a solo marathon to raise money for charity just weeks after the death of his brother, Adam.
Selwood, now assistant coach of Collingwood, had been planning to run in South Africa's Big Five Marathon with Bickmore but was forced to pull out due to the tragic death of Adam in May.
Adam's death at the age of 41 came just three months after his identical twin and fellow former AFL player Troy Selwood died.
Scott's commitment to the cause remained, with him completing 42.2km around Albert Park on Saturday - raising money for Bickmore's Beanies 4 Brain Cancer in the process.
Former player Isaac Smith joined Bickmore in South Africa in Selwood's place, running a marathon with just three week's notice.
'Collapsed against the wall is Scott Selwood, who was due to participate in The Big 5 with us but had to pull out at the last minute due to the most horrific personal circumstances,' Bickmore posted to Instagram.

'He still chose to do the marathon in Australia at the same time as we did ours in South Africa. He ran around Albert Park lake and did the 42K alone. What a superhuman effort.
'The pic of the man laying down is Isaac Smith, a former footy player who stepped in with 3 weeks to go and only managed 3 training runs before running The Big 5 marathon.
'He nearly got medic'd off the course because he was so unwell, but he wouldn't let them stop him running. He completed the marathon, the colour of grey, and stumbling everywhere but he did it. He did it for Scott.
'Sending love to both of you. You are both beautiful humans.'
Alongside the message, Bickmore posted an image of both Selwood and Smith after running their respective marathons.
Smith, who has a newborn at home, said stepping up to run the race was a no-brainer for him.
'There wasn't really a question because they've done so many amazing things for so many people,' he said.
'They're a beautiful family and I'll do anything to help them out.'
Bickmore described Selwood's grueling solo run in Melbourne as a 'superhuman effort'
The AFL was rocked by the sudden death of Adam Selwood aged 41

Before his death, Adam Selwood was meant to run a half-marathon to honour his brother Troy.
He hoped to raise $10,000 for WA charity zero2hero, which supports mental health leadership and suicide prevention.
A group of Adam's friends – including West Coast teammates – finished what he started by running the race.
