Joe Wicks has announced he is planning a 24-hour exercise marathon that he admitted might leave him in tears.
He will work out for 24 hours straight – not even pausing to sleep – in his bid to make millions of pounds for the organisation.
Wicks, whose star has continued to rise since he became “the nation’s PE teacher” amid the coronavirus lockdown, told the PA news agency he knew it would be really tough.
“It will be draining and I know that when you get true fatigue and you’re really exhausted, you get really emotional,” he said.
“I’ll probably end up, at some point, bursting into tears.”
However, the fitness guru added: “Hopefully people will be there to pick me up and say, ‘Come on, keep going’.”
Wicks, 35, admitted his biggest concern is the tiredness.
“I think when it gets to 3, 4, 5am, I’m going to really want to cry myself to bed…” said the father-of two. “It’s going to be savage.”

The star has been advised to consume 10,000 calories during the fundraiser so said he will be snacking on high calorie drinks, avocado and peanut butter.
Wicks will start his PE challenge at 9.25am on 12 November, and he will aim to keep going until 9.25am on 13 November.
During the 24 hours he is planning to mix things up, doing a range of activities including cycling, yoga, boxing and rowing as well as his signature HIIT workouts.
Celebrity guests will join him virtually along the way.
BBC Children In Need chief executive Simon Antrobus said: “We know that the last six months have had a real impact on children and young people’s wellbeing, which is why the money raised by Joe and Radio 2 through this remarkable challenge will go on to help deliver crucial support to children and young people at a time when it is so urgently needed.
“We are so grateful to Joe for taking on this challenge. It’s acts of kindness like this that help to make a difference to young lives and we look forward to tuning in and cheering him on.”
