After a discussion with a friend I've figured out I should ask you guys.
After his insanely inefficient 26:49 back in 2017 worlds 10,000 (crazy pace changes), and considering his latest 15K result (41:05 after a long injury and with incompetent pacers), I started thinking that Cheptegei is worth sub 26:30 on the track with ideal conditions.
What do you guys think he is capable of in every track/road distance? (I know that the full 'thon is sometimes sneaky but I think that HM can be discussed)
