Considered one of the greatest LPGA players of all time, Nancy Lopez began her professional career In 1978, winning nine tournaments. She won multiple times in each year from 1979 to 1984, although she played only half-seasons in 1983 and 1984 due to the birth of her first child. Playing full time again in 1985, Lopez posted five wins, five seconds and five thirds, won the money title, the scoring title and the Player of the Year Award. She played only four tournaments in 1986, when her second daughter was born, but came back to win multiple times in 1987-89. Her schedule was curtailed again in the early 1990s when her third daughter was born. In 1992 she won twice. She retired in 2003, then came back in 2007.

British runner Paula Radcliffe triumphed at the 2007 New York Marathon less than 10 months after she had given birth to daughter Isla, which was impressive enough. But add this: During her 27-hour labor, Radcliffe had suffered a broken sacrum, and that meant an extra two months of no training.
