Tirunesh Dibaba

Dibaba's last-lap kick won three Olympic golds and five world track titles, including the Beijing 2008 5,000m and 10,000m double. Her move to the marathon showed how far that finishing speed could be stretched: she won Chicago in 2017 and ran 2:17:56 in London that year, then among the fastest times in history. Her 5,000m world record from 2008 lasted 12 years, a reminder of how good her track base was.
