Bekele's still the guy
Cheppy's run was impressive. Yep. No doubt about it. Whatever people say about lights or doping controls in Covid or spikes.
However, he bettered the 5k world record by (almost) 2 seconds. Why would you think he can take more than ~5 seconds off the 10k record? Bekele's records are insane, there's a reason Cheppy breaking this is such a huge deal. There's no guarantee he'll even break 26:20. I thought 12:37 was forever unbeatable too, so maybe 26:17 is beatable somehow, but I don't think I'll live to see a sub-26:10 (and I'm young).
