Gladys Lucy Tejeda Pucuhuaranga (born 30 September 1985) is a Peruvian long-distance runner who has represented Peru in various international competitions, including the Olympics and the Pan American Games.

She competed in the women's marathon at the 2012 Summer Olympics,[3] where she was also chosen as Peru's flag bearer for the Parade of Nations.

[4] In 2013, Tejeda claimed victory in the XXXI edition of the Mexico City Marathon, completing the race with a time of 2:37:35.

However, later that year, she was stripped of her medal after testing positive for furosemide, a diuretic included in the World Anti-Doping Agency's banned substances list for its potential use in masking other drugs.

Tejeda achieved further success by winning a gold medal in the marathon event at the 2019 Pan American Games.
