A forthcoming international Ironman competition will go ahead despite a recent E-coli contamination on Irish beaches, organizers have said.

Organisers of the triathlon event, which is set to attract a number of Irish celebrities, said they were satisfied the dangerous bacterial contamination, which has led to the closure of Grattan Beach in Galway, had not spread to the rest of the bay. The news came as swimmers re-entered the icy surf off several southern beaches yesterday, after new tests indicated bacteria levels were falling in sea water.

The 1.2-mile swimming leg of the triathlon will take place from the promenade in Salthill. Athletes will set off from Blackrock out into the bay and return to Palmer’s Rock, along the promenade.

They will then complete a 90-km bike ride finishing with a run around Salthill. A number of Irish celebrities are set to take part, including former Miss World Rosanna Davison, Grainne Seoige, Keith Barry, Brian Kennedy, Matt Cooper and Ray D’Arcy.

I don’t know who any of these people are.
