The Duke of Sussex said the "Invictus spirit" was "even more relevant" given the Covid 19 pandemic as "we face new challenges and adapt our lives" during a webinar with organizers.
35-year-old Prince Harry sent a message to the organizers of Invictus Games, which was posted this week on the charity's YouTube page.
The king, who is currently isolated in Tyler Perry's $ 18 million mansion in Los Angeles after resigning from his royal duty, said the organizers: "This conversation is about sharing the Invictus spirit, and it is even more relevant now as we have to deal with new issues challenges and adapting our lives. & # 39;
The video clip was released days after the announcement that Prince Harry had merged the Endeavor Fund and Invictus Games so that he could continue to work on his decision to step down as Senior Royal.
Prince Harry, 35, said he believed that the "Invictus spirit" in a YouTube video was "more relevant" to the organization than ever before
Prince Harry announced in March that the Invictus games would be canceled due to the coronavirus pandemic.
The organizers said that the competition founded by Prince Harry – scheduled to take place in The Hague last month – is expected to be postponed to May or June 2021.
At the beginning of the virtual meeting, which took place in May, Prince Harry said to the participants: “Hello everyone, I am very pleased to welcome you all to the Invictus Games Foundation's first meeting today.
"We are obviously not in The Hague, but I am so pleased that we were able to organize this virtual meeting when the games themselves took place."
The Duke of Sussex said that in the virtual message we are "tackling new challenges and adapting our lives"
He continued: "This conversation is about sharing the Invictus spirit, and it is even more relevant now that we have to face new challenges and adapt our lives."
"I hope that all nations, competitors, family members and friends will treat each other well during this time to support each other, and I know that you will show the resilience that is so central to the Invictus community."
He added: "I am very grateful to all of you for being here and showing your support, especially the speakers and panellists who shared their experiences."
“I hope this conversation will be the first of many, and I am really looking forward to a time when we can get together again. Thank you very much. & # 39;
The king shared the video message with the organization after the 2020 contest in The Hague was postponed due to the pandemic
Harry was inspired to start the global tournament after participating in the 2013 Warrior Games in Colorado.
At the event, he saw how injured US military personnel benefited from the challenge of participating in competitive sports that supported their recovery.
In 2014 he hosted the opening games at London's Olympic Park, followed by Orlando in 2016, Toronto in 2017 and Sydney in 2018.
Last year the duke met with team members for the Hague 2020 competition, which has since been postponed to 2021
Last week it turned out that the organization was merged with the Endeavor Fund.
@WeAreInvictus wrote on Twitter: & # 39; The Invictus Games Foundation is pleased to announce that the Endeavor Fund has been transferred to the Royal Foundation in the work of the Invictus Games Foundation.
"The Endeavor Fund will continue to support the ambitions of wounded, injured and sick employees and veterans, but is now expanding its activities to the international Invictus community."
The king founded the organization in 2014 and it has been close to his heart ever since. He chose the 2017 event as his first public appearance with Meghan Markle 
The Duke of Sussex founded the Endeavor Fund in 2012 when he was patron of the Royal Foundation – along with brother Prince William and Kate Middleton.
Last year, Prince Harry and Meghan Markle announced that they would be parting from the Royal Foundation when the two couples began to go “different ways” in their charity work, and had to reflect this in different outlets, a source told PEOPLE.
After the Megxit, it was decided that Prince Harry would no longer use HRH or his military honors.
