O'Rourke beat Jenny Kallur when taking the European Outdoor silver medal in 2006 in a new Irish record of 12.72 seconds.

Twenty-year-old Vukicevic won the world junior silver medal in 2006 and she set her outdoor personal best (13.07) at last year's World Championships in Osaka.

O'Rourke will be hoping that the two Scandinavians will provide her with the necessary impetus to record a good early season time in preparation for the World Indoors in Valencia at the beginning of March.

The Cork girl has fond memories of the Odyssey from two years ago where she defeated current World Outdoor bronze medallist Delloreen Ennis London of Jamaica to set a new Irish record time of 7.90 seconds.

Kenyan 800m runner up Richard Kiplagat is also a confirmed entry at the championships where he is likely to face local Irish competition such as Limerick's Liam Reale who got the silver medal at the Odyssey last year behind Justus Koech.

The event also incorporates the Phoenix "Olympic Flames' Age Group Championships and also a 'Search for a Star' Primary School Initiative with children from across the province participating in a final.

The Championships are being organised and promoted by Athletics Northern Ireland and the Athletic Association of Ireland and in conjunction with Belfast City Council and Sport NI as funding partners.
