The fact that the OP is probably correct if you’re thinking in terms of preserving Cheptegei’s reputation and building his legend is actually part of the trouble with running as a sport. Instead of incentivising runners to race often and squaring off against each other, we end up with the best runners only racing when they are peaking, and we almost never get to see the very best face off against each other.
Running as a sport would be much better off with less focus on times, and instead more emphasis on exciting and memorable races. The greatest runners shouldn’t be crowned based on their ability to time trial, but rather their ability to perform when it matters, and create memorable moments over and over again by racing and competing frequently, never shying away from facing their hardest opponents. Legends are created through legendary battles.
Imagine if Sammy Wanjiru scratched ahead of Chicago because he knew he wasn’t at his best? The fact that he didn’t gave us the most exciting race ever witnessed on this side of the Y2K. Moments like that is what makes it great, and what creates legends. A race like that is a hundred times more exciting than a solo world record.
I celebrate Cheptegei for being there, and competing. The fact that he was made the race more exciting. And I’m sure we’ll see him race plenty more in the future. His 2017 World Cross race showed that he’s a runner who’ll compete, and leave it all out there.
