Abebe Bikila

No. There have been several. Don't forget about Zola Budd [at left :)]. Jason Robillard was going to compile a list of all the barefoot runners who have won races.
 
I forgot Dekkers! (80's NCAA champ) :eek: BTW, does Zola still run bare?

Yes, she does still run barefoot, just not on hard surfaces. She says she still trains barefoot and will run on cross-country courses and tracks (not asphalt) barefoot to keep her feet strong. She doesn't race barefoot anymore though. After all, she is Newton's spokesperson.
