Nick Grimshaw was "proper exhausted" when his 100-mile desert crossing got hit by a rainstorm.
The BBC Radio 1 DJ – who will be walking, cycling and dune-skiing across the Namib Desert alongside the likes of Frankie Bridge, Rob Rinder, Samantha Womack and Louise Minchin – was shocked when it started raining during the ‘Sport Relief’ challenge, and he didn’t bring a waterproof for the challenge.
He’s quoted by The Sun newspaper’s Bizarre TV column as saying: "I didn’t bring a waterproof, as when would it ever rain in the desert?
"I’m proper exhausted. This is the worst I’ve ever felt. It is so much harder than anything I have experienced.
"I’m falling off my bike constantly but have to keep going. I’m keeping pace with Louise, my bike buddy. But Rob is so fast. He’s probably at Heathrow already."
The group were originally due to take part in ‘On Thin Ice in Mongolia’ for the challenge, but things had to be moved around because of concerns over the coronavirus in neighbouring China.
Nick, 35, recently admitted he was unsure whether the sudden change will make it "better or worse".
He said: "It’s still great to do it. However I can’t work out if it’s better or worse."
The challenge – which also features Krishnan Guru-Murphy and Karim Zeroual – has been renamed ‘Sport Relief: The Heat Is On’.
Comic Relief interim chief executive Ruth Davidson said: "We had previously been looking at a range of locations and challenges and we think that the Namib Desert expedition is a fitting alternative.
"We are extremely grateful for our team of celebrities who have not wavered in their passion and determination to want to take on a challenge for us, which is extraordinary in itself."
A BBC One documentary following the fundraiser will be shown in the run up to ‘Sport Relief’ on March 13.
