William, 38, made a video in support of a virtual marathon that usually takes place in Lewa in Kenya. But this year supporters of his conservation charity Tusk Trust have been running, walking or riding distances from three miles o 26 miles on roads, parks and fields elsewhere. Looking tanned in a bright white Abercrombie and Fitch polo shirt, William tells supporters, “I’m also about to do a run myself, as part of this virtual challenge.” “Like many of you, I’m very sad not to be able to do this run in Lewa’s beautiful surroundings — but also rather relieved to have been spared the altitude and the heat." William, who has been patron of Tusk since 2005, adds, “This is not a race, there is no stopwatch. It is our way of showing Africa’s conservation community that we’re all in this together.” Prince William Shares Umbrella with Prince George and Princess Charlotte in New Family Photo The royal's run will surely offset the hobby he's taken up during lockdown: baking with his three kids — Prince George, 6, Princess Charlotte, 5, and Prince Louis, 2! "I'm worried about the waistline of the nation as well with all the chocolate and cakes," he said during his first public appearance since the coronavirus crisis gripped the U.K. on June 16. "I've done a lot of baking at home. Chocolate goes down very well." Prince William was also gifted a birthday cake during a recent visit to family-owned bakery Smiths The Bakers. Prince William.

And in Kenya, a unit of rangers, armed guards, and staff set out on the original Lewa Marathon track. Head of Anti-Poaching Edward Ndiritu said in a statement on the Tusk website, “We [may] not all be running together. [But] wherever you are, we want to achieve the same objective.” Can't get enough of PEOPLE's Royals coverage?

Funds raised from the virtual event will support the men and women on the frontlines of conserving Africa’s unique wildlife, Tusk says. Thanking people for their effort, William said he fears COVID “threatens to undo years of conservation progress” across Africa.
