Lynn Jennings. Jennings dominated the cross-country world during the 1990s, winning the USA Cross-Country Championships nine times and the IAAF World Cross-Country Championships three consecutive times. She also won an Olympic medal in the 10,000-meter. Nope, not an over-achiever at all.

Tirunesh Dibaba. Nicknamed the "Baby-Faced Destroyer," this Ethiopian national holds the world record in the outdoor 5,000-meter. She's also an Olympic and world champion in the 10,000-meter. You go, girl.
