It could hardly have been closer. Celebrity Race Across the World (BBC One) climaxed with a breathless foot chase to the finish line. Broadcaster Roman Kemp and his sister Harleymoon (you don’t meet many of those) signed the all-important book first and were crowned the winners – a mere 20 metres ahead of lovebirds Molly Rainford and Tyler West. I found myself leaning forward on the edge of my seat as this white-knuckle dash unfolded.
