The Taoiseach, Mr Ahern, will undergo a security check by the Garda after becoming the first person to apply to become a Special Olympics volunteer.
His application was received at a ceremony in Dublin yesterday and the Games' organisers hope it will be the first of 30,000 such applications from people willing to get involved in helping run the biggest sporting event taking place in the world next year.
The 2003 Special Olympics, which takes place over nine days in June, is being hosted by Ireland with 160 countries taking part. An estimated 10,000 athletes will participate.
The Special Olympics are open to athletes with a learning disability or mental handicap.
The Taoiseach said he had "no doubt" that the Games' Organising Committee would achieve its target of recruiting 30,000 volunteers to work in everything from providing medical assistance through helping with the horses, to helping with transport, language and catering needs.
"People will ask, 'What's in it for me if I volunteer'?" he said. "Well, I'll tell you: Nothing. Nothing more than an unforgettable experience that will only come your way once in a lifetime."
Mr Brody Sweeney, chief executive of O'Brien's Sandwich Bars, the main sponsor of the Games, said he hoped the event would serve to "raise awareness of mental handicap and destigmatise it".
Ms Mary Davis, chief executive of the Games Organising Committee, explained all applicants would undergo a Garda background check "to ensure they would not be a threat to security" and "all applicants will undergo this no matter who they are".
