O'Leary in 24-hour dance marathon
Comic Relief's dance marathon man Dermot O'Leary has limbered up for his 24-hour ordeal with a training session at London's Pineapple Dance Studios.
The TV presenter and DJ will kick off his day of dancing on The One Show on Thursday March 12 before toe-tapping his way from the BBC's New Broadcasting House to the London Palladium for a grand finale on Friday night.
He said: " When I came up with the idea for this event I was in the middle of the dancefloor on holiday, where you never want the dancing to end.
"Now I'm back in the freezing cold UK with a few less disco lights and a lot more bruises - and it doesn't seem quite as appealing. I'm going to need all the support I can get from the public to keep me going."
O'Leary, who fronts a show on Radio 2 as well as presenting ITV's The X Factor, also took advice from endurance expert and sports scientist Professor Greg Whyte.
Prof Whyte said: " Although it sounds fun, there are lots of risks with taking on this dance. Putting your body through any sort of endurance test will always take its toll, but for such a huge amount of time and with such sustained physical movement there is a lot that could go wrong.
"Knee, hip and ankle injuries, muscle strains and blisters are just the start - as sleep deprivation kicks in combined with exhaustion and dehydration the possibility of falls and impact injuries are a real risk.
"If Dermot thinks he'll be sailing through his sidestepping, he's got another think coming."
