Udrea's first sports were swimming and tennis. She discovered fencing at the age of seven at Olimpia Bucharest, and took to the sport. She first competed in
foil. In this weapon, she won a silver medal in the 2008 Cadet European Championships at
Novi Sad, a gold medal in the Junior World Cup in 2009, a bronze medal in the Junior European Championships at Odense that same year, and a silver medal in the 2010 Romanian Championship. The year after, Romania were knocked out by Venezuela in the first round of the
World Championships in Paris. The lack of results and funds pushed the
Romanian Fencing Federation into dissolving the national foil team in early 2011. Udrea then turned to épée. In March 2013, she won a silver medal in the Romanian national championship after being defeated in the final by teammate
Ana Maria Brânză, with which she won a team gold medal. In July, Udrea won a silver team medal with Brânză,
Simona Pop and
Amalia Tătăran in the
2013 European Championships in
Zagreb. In the
2013 World Championships at
Budapest, she was defeated in the table of 32 by Italy's
Rossella Fiamingo, but earned the team bronze. She ended up 47th in the
2012–13 Fencing World Cup. In the
2013–14 season, Udrea was selected as reserve for the
2014 European Championships in Strasbourg. In the individual event, she was stopped in the table of 64 by France's
Marie-Florence Candassamy, who eventually won the silver medal. In the team competition, No.2 seed Romania received a bye, then disposed of Ukraine 45–31, beat Italy 29–24 in the semi-final and overcame Russia 38–34 in a very tight and tactical final, allowing Udrea to win her first international gold medal. Udrea did not compete in the
World Championships in
Kazan as
Ana Maria Constantin was selected as reserve in her place. ==References==
