Harry Byrne with Reuben. See SWNS story SWBRmoon; A seven-year-old is on a quest to race around the moon to show his love for his seriously ill little brother. Harry Byrne captured hearts earlier this year when he took on a 50-mile hike for a children's hospice who care for his brother Reuben. Reuben, who turns two in September, was born with a condition that causes his brain to deteriorate so rare it doesnt have a name yet, and there are fewer than 20 recorded cases worldwide. But now that lockdown restrictions have eased, Harry has decided to venture much further with his fundraising hes got his sights set on space. With help from his family, friends and other fellow moon trekkers, Harry, from Larkhill, Wilts., hopes to complete the 6786-mile distance around the moon in just three months. As well as leading three fancy dress walks past Stonehenge on the full moon days, the St Michaels C of E Primary School pupil plans to clock up the miles by climbing mountains, running with his football friends and lots more.
