Harry Judd has been forced to take his London Marathon training slightly easier after he was diagnosed with a heart condition.
The McFly drummer, 27, admitted he was 'annoyed' after being diagnosed with an ectopic heartbeat, otherwise known as wandering pacemaker.
The Strictly Come Dancing 2011 champion was diagnosed with just three weeks to go before he runs 26 miles for charity.
He tweeted on Tuesday: 'So I've acquired and [sic] ectopic heart beat through excessive exercise. It's known as a Wandering Pacemaker commonly seen in athletes....
'...It takes causes symptoms or requires treatment. Still it's really annoying!!!
'It proves I've even pushing as hard as possible for the marathon + if u've been thinking of sponsoring me then surely that will pursuance u? (sic).'
He added: 'It's nothing to worry about but just means I have to chill out a bit :-/.
'Athletes get it though... :-).'
Harry is raising money for the Teenage Cancer Trust and his wife Izzy Johnston's appeal Eyes Alight, which was inspired by her brother Rupert, who suffered a brain injury following a car accident in 1997.
Together with four friends, Harry will run 26 miles for the Virgin London Marathon on April 21.
Two weeks later, they will take part in Tough Mudder, a 13 mile assault course through a range of obstacles.
