... And they're not running to stand still anymore.
Contrary to recent reports, U2.Com are happy to underline that Ballymun, in the north of Dublin - close to the hearts of both Larry and Bono - is in better shape than ever.
One recent online story about 'U2's Dublin' described the area, immortalised in the band's 1986 song Running To Stand Still, as 'bad' .
It went on to warn fans 'do NOT go here on foot.'
Well, they obviously haven't been there recently - Ballymun is being transformed, thanks to a huge €1.8bn regeneration scheme.
And Bono, who grew up in nearby Glasnevin, says 'he's very proud to come from the Ballymun area.'
Small wonder that local people are upset that a drug problem which it faced 20 years ago, is being dragged up to knock the area again.
'Ballymun is not an area where you have to fear for your life,' said Poppintree community worker Jimmy Gilchrist. 'It's far from that.'
