Double world record holder Gillian O'Sullivan will lead the Athletics Ireland 20k team in the European Cup of Race Walking in Russia on May 19th.
The Killarney star is unbeaten this season and set a world indoor record in the national championships in Belfast in February. She also won titles in Mexico and Milan.
Olive Loughnane will join O'Sullivan on the team.
Cork's Robert Heffernan leads the men's 20km team of Colin Griffin (Ballinamore) and debutant David Kidd of St Laurence O'Tooles in Carlow.
But the team has been weakened by the forced withdrawal of national 50km record holder Jamie Costin due to a hip injury.
Heffernan finished seventh in his first 20km of the season in Milan and will be keen to improve after his eighth position at last summer's European Championships in Munich.
The junior women's team contains another up-and-coming walker in 16-year-old Ann Loughnane, who is already installed as one of the favourites for the World Youth Championships title in Canada in July.
