Hundreds of Canberrans have raised more than $15,000 for Elijah Arranz, the teenager critically injured in a skydiving fall that claimed the life of his tandem instructor.
More than $15,385 dollars had been raised in less than four days via a Go Fund Me page to support the 14-year-old's rehabilitation.
The sporting community has rallied behind the teenager, who was in a serious but stable condition at Westmead Children's Hospital as of Friday afternoon, a spokeswoman said.
It is believed Mr Rokov, 44, who crashed to his death, wrapped himself around Elijah to cushion him from impact.
Ginninderra Athletics will be collecting donations for Elijah's family during Saturday's Beyond Bank Ginninderra Carnival, celebrating the club's 40th anniversary.
Each athlete in midday's 1000-metre race will wear the teenager's registration number in recognition of their fellow athlete, who would have competed in the event.
Club president Phil Henderson said Elijah was a selfless young man whose kind actions shone.
When he was 10 years old Elijah raised $5000 as part of the World's Greatest Shave, cutting off his long locks in support of Kaleen Primary School classmate Christopher Nell, who had blood cancer.
Elijah was featured in The Canberra Times earlier this year after he vowed at the age of 12 to run every day for more than a year, capping off the challenge by taking part in the Australian Running Festival to raise money for the Make-a-Wish Foundation.
Just a couple of weeks ago the teenager gave four pairs of old running shoes to a 21-year-old man with autism who had a fascination with the footwear.
"He is a great individual," Mr Henderson said.
"For his 14th birthday present to go so horribly wrong, it's pretty sad."
Mr Henderson said he hoped the extra support would help Elijah get back on his feet sooner.
A portion of the thousands of dollars raised via the Go Fund Me page will also be donated to the family of Mr Rokov.
"It's going to be a tough comeback [but] he's one of those tenacious kids who just keeps fighting," Mr Henderson said of Elijah.
"I hope we'll help get him on his feet and maybe even back on the track."
The club is also hosting a fund-raising dinner and auction on Saturday, February 6, at the Southern Cross Club, Woden, with tickets, from $75 a head, on sale next month.
Elijah's basketball club, the Ginninderra Rats, has also shown its support for the active teen by asking players to don bright, colourful socks as a show of support during the weekend's games.
