The Invictus Games in the Netherlands will be among the Duke and Duchess of Sussex's first public appearances together after they step back as senior royals.
Prince Harry and Meghan are due to join spectators at the competition in The Hague this May.
The couple's lives as working royals will end on 31 March, when they stop representing the Queen and become financially independent, with the arrangement being reviewed after 12 months.
The Duke founded the Invictus Games in 2014, and remains patron of the Invictus Games Foundation.
In January, the chairman of the Invictus Games Foundation told Forces News Prince Harry remains committed to the tournament.
Harry and Meghan made their first public appearance together as a couple while attending the 2017 competition in Toronto.
Prince Harry and Megan will attend the Commonwealth Day service at Westminster Abbey on 9 March, likely to be their last official appearance as working members of the monarchy, with the Queen and other senior royals.
As part of his new life away from being a senior royal, Prince Harry will retain the military ranks of Lieutenant Commander in the Royal Navy, Major in the British Army, and Squadron Leader in the Royal Air Force that he was awarded in June 2018.
The Duke of Sussex will, however, step down from his military appointments, including being Captain General Royal Marines, a role which he was awarded in December 2017, succeeding the Duke of Edinburgh.
He will also stop being Honorary Air Commandant of RAF Honington and Commodore-in-Chief of Small Ships and Diving, Royal Naval Command.
