In an ultimate test of endurance, entrants pushed their machines and bodies during The 24 Hour Motorbike Trial on the weekend under a mixture of weather conditions.
"It was cold and wet on the top and bottom sides of the course, with breezy conditions in the hills making an ideal flowing course," Competition secretary Chris Caust explained.
Run since 1924, Mr Caust describes round four of the seven run series as "The Bathurst of the V8s".
"Bathurst is both a popular sport on and off the track and so is The 24-Hour...and is the best run," he said.
This year's event attracted about 140 riders in the solo, sidecar and rally sections from Victoria, NSW, QLD, WA and as far as Wales due to a special licence obtained by the committee.
And of course hoards of spectators settled in across the three spectator points to view the action.
The undulating course began in Eudunda, taking in council zones and was "purposely marked" which Mr Caust said took into consideration rider safety and also to prevent land damage.
Despite a few rider mishaps resulting in medical attention, all entrants were ticked off on Sunday with results to be revealed later this week. It is also yet to be determined how many completed the course in their sections.
"We are still loading time cards and can't reveal any details until usually the end of the week," he said.
For Mr Caust, who has ridden the event nine times, it was a usual day in the office sharing how the 24 controls were well manned and "everything under control".
He and the committee thank the landowners, the control operators and volunteers which are estimated into the hundreds.
The presentation will be held on Saturday, August 17.
