Pitsiladis is a great scientist - over the last two decades, the guy has made incredible contributions to our understanding of running physiology, from genetics to biomechanics to anthropology. He launched the original “sub-2” project before Nike (publicly) did, but with a focus on trying to develop and harness physiology. He even had a project where he was trying to identify promising teenagers in Kenya and Ethiopia early on, to start training them optimally early (essentially the Ingebrigtsen approach on East Africans) understanding that no one today could physiologically do it clean.
He was critical but cordial about Nike’s breaking 2 project when that all happened, and now it sounds like the patience is gone. It’s a bummer, as his work driving towards the “clean and fair sub2” has been incredible.
