Competition will take place from dawn to dusk tomorrow, with Australians and New Zealanders encouraged to record 2504 metres as many times as possible on their indoor rowing machines. 

The distance has been chosen to signify the date of Anzac Day - April 25. 

Anzac Day is an annual event observed by Australia and New Zealand to commemorate the citizens of both nations who served and died in all wars, conflicts and peacekeeping operations.

Participants are encouraged to log their metres online and donate to either Returned and Services League of Australia’s Anzac appeal or the Royal New Zealand Returned and Services Association. 

"What better way for our rowing communities to acknowledge this year’s Anzac Day, and respect our current lockdown restrictions, than to row at home in honour of all those that have served and continue to serve our countries," said two-times Olympic gold medallist and eight-times world champion rower Eric Murray of New Zealand.

"The Anzacs rowed into Gallipoli, on April 25 1915, and this Anzac Day, Australians and New Zealanders will unite at home to row indoors and honour their memory."

Restrictive measures are in place in both Australia and New Zealand due to the coronavirus pandemic, with the usual Anzac Day events unable to be held. 

"As with all New Zealanders and Australians, our athletes are facing challenging times, and we are incredibly proud of their commitment to honour Anzac Day within our respective lockdown restrictions," said Rowing NZ chief executive Simon Peterson.

"Whilst we are saddened normal commemorations are unable to take place this year, we are humbled to have the New Zealand and Australian rowing communities joining us in honouring our defence forces."

The country who recorded the most 2504m per participant is set to be announced on Sunday (April 26).
