Dynamic duo Sid James and Ironman Kevin Fergusson are gearing up again for their latest challenge: The 2021 Wings for Life World Run.
On May 9, people from across the world will run as one, raising funds and awareness for spinal cord injuries.
This is a cause close to Victor Harbor Triathlon organiser and former triathlete Mr James' heart.
In 1993, at the age of 35 while training in Victor Harbor, Mr James was knocked from his bicycle and rendered a quadriplegic.
He has not let his injury slow him down however, and with the help of Mr Fergusson, has completed a number of endurance events including the Busselton Ironman, Sufferfest Murray Bridge (half Ironman), the McLaren Vale half marathon and the City to Bay.
This will be the third time the pair have taken part in the World Run - with Mr Fergusson towing Mr James - and marks their first event together in some time.
Mr James was recently hospitalised with pneumonia and Mr Fergusson has been recovering from neck surgery.
"I can't wait to get back out there with Kevin and take part in another event," Mr James said.
"It's going to be great fun and it is really promoting and supporting an important cause."
The pair have been friends for about 30 years and Mr Fergusson said he got great enjoyment out of competing with Mr James.
"We've got a special bond and I take a lot of pleasure in being able to help Sid achieve his goals," Mr Fergusson said.
"To get him the Ironman medal at Busselton in 2018 was really special and it's going to be great to get out together again for the first time in a while."
Mr Fergusson said the Wings for Life World Run was a great event and encouraged others to get involved.
"100 percent of donations and entry fees go to spinal injury research and it's only $15 to enter," he said.
"It's a fantastic event and there was a big crowd last time we entered, so we are both really keen.
"It's something different and I'd really encourage people to get involved or support the cause."
The 2021 Wings for Life World Run begins at 8.30pm at Victoria Park, Adelaide; in sync with other events across Australia and around the world.
Participants race side by side globally, as they fight to stay ahead of a virtual 'Catcher Car' which steadily increases its speed.
Mr James and Mr Fergusson will run under their team 'Sid and Kevin Will'.
