On April 10, 2011, less than a month after placing fourth at the City-Pier-City Loop half marathon in The Hague with a new national record, Stublić competed at the Linz Marathon. She won her second marathon race, clocking 2:30:46, ten minutes ahead of the rest of the women's field, and nearly three minutes faster than her previous personal best and national record. Her time qualified her for the 2012 Summer Olympics, making her the first Croatian marathon runner ever to qualify for the Olympic Games.
