The European Champion Clubs Cup Track & Field Juniors group A will take place in Castellon, Spain, and group B will be held in Leiria, Portugal.
Both events will take place on Saturday 17 September during a single day of competition.
The men and women compete separately and only clubs recognised as national champions the preceding year are eligible to take part in the events.
The order in which the clubs’ nation were classified the previous year determines whether a club is promoted into group A or relegated into group B.
The clubs are classified from first to last place by adding all the points won throughout the day.
Last year in Istanbul, Spain’s Playas de Castellon lifted the men's junior group A trophy. On the women's side Turkish club Fenerbahce were the winners.
In group B last year in Leiria for the men it was Italy’s Atletica Vicentina Club who took the win, on the women’s side it was Dutch club PAC Atletiek who triumphed.
