A meeting of sports ministers is due to take place in Cardiff to outline how Wales and other parts of the UK can benefit from the 2012 London Olympics.
The meeting, at the Wales Millennium Centre, will be chaired by the UK Culture Secretary Tessa Jowell.
Among the speakers will be chair of the London organising committee Lord Coe, who will outline benefits for Wales.
During the bid process, it was suggested Cardiff's Millennium Stadium could host Olympic football matches.
The Wales National Velodrome in Newport, the National Pool in Swansea, the National Indoor Athletics Centre in Cardiff and the Plas Menai National Watersports Centre have all been put forward as a possible pre-games training venues.
Those involved in the games have also spoken of the spin-offs for tourism and the economy, and benefits in the health and fitness of the population of Wales and other UK regions.
Wednesday's meeting in Cardiff will be attended by UK sports ministers including Welsh Sports Minister Alun Pugh, as well as games organisers.
Training camps
Lord Coe, chairman of the London Organising Committee of the Olympic Games, said Wales would benefit in many different ways.
"In the build up to 2012 we have a golden opportunity anywhere in the country to really enhance participation in sport, to really put sport higher up the social and political agenda, which really has big funding implications," he said.
"Wales has an opportunity to be the host to many visiting countries that will want to prepare properly for an Olympic Games. Preparation is not a luxurious add on. The opportunity to attract other events into all our nations and regions off the back of an Olympic Games in the next seven years is profound."
UK Sports Minister, Richard Caborn, who is also attending the meeting, said: "The support we got from Wales was absolutely fantastic.
"Now we've won it we are looking at how we can have an effect right across the UK."
Mr Caborn added he believed Wales could be used as a base by competing countries.
"There were 202 teams competing in Athens and I think it will be the same number in 2012 - big teams from China, Australia so on will be coming to the UK weeks before the games to acclimatise," he said.
"I understand the Chinese have already been visiting here and making noises that they are wanting to look at parts of Wales to bring their holding camp.
"I will be very surprised indeed if Wales does not attract some of the major teams here in holding camps.
"If it's anything like previous games, they won't just be training, they'll be going to schools, they'll be involving themselves in the community."
