Can you name five out of the hundreds of championship races? Leading, off of a decent pace even jeopardizes premium runners in their heats of a 1500. It is rare that someone is so much better than the field that they can ignore tactics.
Keino came to my mind immediately. However, don't you think that there were extraordinary circumstances with the altitude of Mexico City and an athlete born, raised, and trained at altitude? And that is only one example, not a trend.
Hindsight is usually pretty clear, but I believe that if JI had laid off the lead until somewhere between 300-500 to go that he would be the 2022 WC champion at 1500 meters. He not only took the lead early, but fought to do so. He did not quite have the oomph needed after his momentum was disrupted late. Was this the difference?
I stand by leading a championship 1500 early, especially at a solid/fast pace, will usually end badly unless the leader is vastly superior to the field and that is rare.
