Irina Konstantinova

Twelve years after competing in her first Olympics, Konstantinova qualified for her fourth Bulgarian team, as a 36-year-old, in the RS:X class at the 2012 Summer Olympics in London by receiving a berth from the ISAF Sailing World Championships in Perth, Western Australia. Delivering a mediocre effort in the opening races, Konstantinova dropped to twenty-second place overall in a fleet of twenty-six sailors with a net score of 180 points.

At the 2008 Summer Olympics in Beijing, Konstantinova narrowly missed out on the medal race by four points, as she finished twelfth overall in the newly introduced RS:X class with a net score of 101.

Konstantinova made her official debut at the 2000 Summer Olympics in Sydney, where she placed twenty-fourth in women's Mistral sailboard with a net score of 193 points. At the 2004 Summer Olympics in Athens, Konstantinova posted a remarkable grade of 152 to pull off a nineteenth-place effort in the same program.
