Breda Dennehy-Willis represented Ireland in the women’s 5,000 metres and 10,000 metres at the 2000 Sydney Olympic Games.

From Bandon, Co. Cork, she joined Bandon Athletic Club in 1982 and won multiple Irish titles through the juvenile and senior grades before earning a scholarship to Western Kentucky University in the United States.

A two-time Irish national champion, she holds personal bests of 15:12.83 for the 5,000 metres and 32:11.30 for the 10,000 metres – both set in 2000 – and remains fifth on the Irish all-time lists for both events.

She competed at the 1999 World Cross Country Championships in Belfast and at the SPAR European Cross Country Championships before her Olympic debut. She is married to Lee Willis, an American academic, and settled in the United States after her athletic career.

Her daughter Róisín Willis, born in Wisconsin in 2004, became one of the most exciting middle-distance runners in the world – winning the World Under-20 800 metres title in Eugene in 2022 in a championship record of 1:59.13, and anchoring the United States 4×400 metres relay team to gold at the same championships on her 18th birthday.
