Prince Harry tried his hand at snowboarding during his visit to training camp for next year's Invictus Games in Whistler, Canada.
The Duke of Sussex and his wife, Meghan, met rivals at Whistler Blackcomb ski resort on Wednesday.
The pair will meet more athletes at the 2025 Games host sites in Whistler and Vancouver.
The Duke founded the Games in 2014 for injured and sick military personnel and veterans to aid in their recovery.
About 550 competitors from up to 25 countries will participate in events including sitting volleyball, swimming and wheelchair basketball at the 2025 Games.
Winter sports such as alpine skiing, snowboarding and wheelchair curling will be part of the competition for the first time.
The Duke was inspired to hold the Games after watching the 2013 Warriors Games in the US, where injured and retired service members competed.
The first edition of the Games was held in London in 2014, and subsequent competitions have been held in the United States, Canada and Australia.
The five-part documentary series, Heart of Invictus, tells the story of the sporting competition the prince organizes for injured and disabled servicemen and women.
Prince Harry said he wants Invictus to act as a safety net to catch people, because he lacks support or understanding of his “invisible injuries”.
Prince Harry and Meghan this week launched a rebranded website sussex.com in an online overhaul.
