She participated in the 2004 Irish National Indoor Championships in Belfast, Northern Ireland, where she won the 400 metres in a new all-comers record of 53.50 seconds over Moushaumi Robinson. As a result of her win, she was automatically selected to be part of the Irish team for the 2004 IAAF World Indoor Championships held the following month. At the championships, Cuddihy finished sixth in her heat of the 400 metres, failing to progress further. She was also part of the 4 x 400 metres relay time with Michelle Carey, Karen Shinkins, and Ciara Sheehy. In July 2004, Cuddihy came second in the Irish National Championships behind Shinkins.

At the 2005 World University Games, Cuddihy made it to the semi-finals of the 400 metres, but failed to progress further after finishing fifth.

In the eighteen months prior to July 2006, Cuddihy suffered from glandular fever and underwent operations on the cartilage on both knees. At the 2006 National Track and Field Championships, Cuddihy set a personal best time of 23.33 seconds to win the 200 metres title, and set a championship record of 51.28 to win the 400 metres.

In 2007, Cuddihy decided to take a break from her medical studies and focus exclusively on her athletics for a full year. In April 2007 Cuddihy moved to Los Angeles in the United States for specialised coaching with Dan Pfaff. On 9 June, Cuddihy won a 200 metres race in Vancouver, British Columbia, Canada with a time of 23.80 seconds.

In the semi-finals she recorded a personal best time of 50.73 seconds, setting a new Irish national record and making her the first Irish woman to have run under 51 seconds at 400 metres. Despite this, she did not qualify for the final. Her new Irish record also qualified her to compete in the 2008 Olympic Games in Beijing, China. In early and mid-2008 she suffered from knee problems, however, jeopardising her ability to compete at the Olympics. Despite the injury, she competed in the heats of the 400 metres but was unable to qualify for the semi-finals. She stated that competing in the Olympics "would have been a dream come true if [she] wasn't injured".

In early July 2009, she participated in the 200 metres at the World University Games, successfully reaching the semi-finals. She finished her semi-final with a time of 24.53 seconds, leaving her in fifth place, which meant she did not reach the final. Cuddihy did not participate in the 2009 World Championships in Athletics, as she had taken time out to focus on her academic studies. Following a hiatus, Cuddihy returned to athletics at the Melbourne Track Classic in March 2010, where she placed third in the 400 metres with a time of 52.95 seconds. In early July 2010, Cuddihy won the Irish National Championships in the 400 metres with a time of 52.76 seconds. At the 2010 European Athletics Championships in Barcelona, Spain, Cuddihy made the semi-finals, but was unable to make the final after finishing fourth in her semi-final and missing a fastest loser position. She was also a member of the Irish 4 x 400 metres relay team alonsgide Marian Andrews, Brona Furlong, and Michelle Carey which failed to progress from the heats after finishing sixth.

In 2011, Cuddihy moved to Australia for full-time training.
