Not only would ADF members deployed on Operation Accordion walk 500 miles, they'd run 500 more. 

Personnel at Australia’s main operating base in the Middle East region have completed an incredible 1000km of non-stop running for a 10-hour period. 

The 'Dusk Till Dawn' fun run involved teams of four, swapping in and out continuously from 7pm to 5am the following day. 

Headquarters Joint Task Force 633 educational officer Captain Amanda Jenner said the event exceeded hopes. 

“With COVID-19 causing the closure of the gym and other restrictions being implemented for social events, personnel from the base started developing creative ways to exercise and maintain social connections,” Captain Jenner said. 

“This was one of many challenges that has been completed and continue to be run, even with some of the previous restrictions easing."

Forty runners plus support crew took part.

It was a great chance to do something that we all love with like-minded people on deployment.

“The results were incredible, with the participants running a collective total of 1073km in the 10-hour period,” Captain Jenner said. 

Despite the competition, teams supported each other throughout the night. 

“These types of events build and maintain morale," Captain Jenner said.

"There is a certain energy, buzz and healthy banter around the camp in the lead-up to the event and a connection with people post-event, knowing that we have all been through the challenge together.”

Executive Officer for Air Task Group Squadron Leader Andrew Fisher ran a total of 27km, while his team, ‘Hot Weather Working Dress’, completed an incredible 117km. 

“It was a great chance to do something that we all love with like-minded people on deployment,” Squadron Leader Fisher said. 

“Everyone was cheering others on especially if they were struggling and when someone was looking really strong; there were some impressive runners that took part.”

Squadron Leader Fisher said apart from the first lap back after each break, the hardest part was trying to ignore the clock.

“I think everyone started to feel it around midnight. When it hits you that there was still another five hours to go – that was a sobering moment," he said.

“Thankfully there was a good buzz in the air, lots of banter and a constant supply of lollies to keep us all motivated.”
