Kenenisa Bekele

Bekele's track record is close to untouchable: three Olympic golds, five world titles and 5,000m and 10,000m world records that lasted 16 years. On the roads his kick was less decisive, and injuries made his marathon years patchy, yet when fit he was astonishing, running 2:01:41 in Berlin in 2019. He shows that track speed transfers, but only once a body can absorb marathon training.
