Several long threads have been thrown together suspecting that Cheruiyot will front-run at an astonishingly swift pace to the tune of sub-3:30.
The contenders have been ranked by the Lets Run faithful based on PRs (as are those who are being given no chance to medal, whatsoever).
If one reviews the sub-3:30s this decade, you'd notice that no 3:30 times have been recorded in oppressive heat (conversions aside, none of the current crop of Olympians has actually run a 3:2x in 30+ temperatures). For those keeping score, Paris 2018 was contested in 31C temps; those sub-3:30 Monaco PRs in 2019 were set in 27C (51% humidity) conditions; Cheruiyot front-ran his 3:29 Doha in 24C/64%; Monaco 2018 was run in 27C conditions; and Cheruiyot won Lausanne's 3:28 in 28C/48.
The National Stadium's track temperatures, peaked at +44C yesterday, something that would unequivocally qualify as oppressive.
Given current conditions, I'm inclined to believe that there won't be any takers for a gun-to-tape run (in oppressive heat), which would indicate to me that the race won't be 3:30 from the start.
Those who prognosticate Hocker as an also-ran are basing this on his slower PR relative to the field, yet again on a premise that the field will run 3:30. However, if the field goes out in 3:32-3:33 pace, one...two...three US athletes proved they can handle the proverbial and literal heat to make podiums in a kicker's final.
Has Tokyo, its heat and current results given you more perspective on the overall field's chances to sneak through and do some damage?
