If it's Usain Bolt for lightning speeds,it's gotta be this guy for long-distance running. If Bolt won the 100-200m double in the World Championships in Berlin,this guy won the 5000-10000m double, which is unparallelled.Hs is considered to be the best long-distance runner the world has ever seen.Name him.

Kenenisa Bekele won the unprecedented 5000m-10000m double at the 2009 World Championships in Berlin, mirroring Usain Bolt's sprint double. He is widely regarded as the greatest long-distance runner ever, with multiple world records and Olympic gold medals. Haile Gebrselassie is another legendary Ethiopian runner but didn't achieve this specific Berlin double.
