Tess Daly and Claudia Winkleman revealed they are in “agony” as they crossed the half way mark of their Comic Relief danceathon.
The Strictly Come Dancing duo are attempting to dance for over 24 hours straight in a bid to raise money for the charity.
The pair, who are hoping to break radio host Sara Cox’s 2017 record, kicked off their stint on BBC Radio 2 on Monday at 7:15pm.
Lorraine’s entertainment reporter Dan Wootton visited the pair with breakfast treats on Tuesday morning and told viewers he heard Winkleman “screaming and yelping” during a quick four minute break.
“You’re allowed four minutes every hour and they give us an ice bath where we put our feet in so we don’t get blisters and swell up,” Winkleman said.
Daly added: “It’s agony!”
The pair also showed off the bandages covering their backs to help with the continual dancing.
They have been showing off their moves to music dating from the 60s through to the present day in a bid to smash the record, and have been visited by their husbands and children.
Victoria Derbyshire, Emily Maitlis and former Strictly judge Arlene Phillips have also made appearances to cheer them on.
Winkleman and Daly’s danceathon can be livestreamed via the BBC Red Button and across all BBC Radio 2 shows.
They kicked off the attempt to Beyonce’s Crazy in Love, telling DJ Jo Whiley they were feeling “slightly wobbly”.
Winkleman said: “I know it’s going to be hilarious to watch because we’re pretty bad dancers – I’m not very good at standing, let alone dancing.
“Thankfully we’ll have each other and we’re going to push through to raise as much money as we can for Red Nose Day.”
Comic Relief 2019 is on BBC One, Friday at 7pm
