It can be hard to get reliable information, and I've heard conflicting reports on East Africans running to school as children.
Haile definitely did run to school - he's famous for the abnormal carriage of his book-carrying arm.
Tergat did not run to school - he's stated it was not far away and he simply walked there. I've seen this quoted in his own words across the internet.
If you have reliable information (not just "what are you talking about? of course all Africans run ten miles to school every day that's how they get so good OMG are you just dumb!!) on whether any specific world-class East African runner ran to school in the morning, please post here.
