question about allan wells training

while looking at allan wells training on this forum, charlie mentioned that his method had been adapted from an older method and that people had run absurd unofficial times using it. my question is who used it and what were the times? i couldnt find anything using a search.

These were professional runners of approx 120 yrs ago. I don’t know much about the history but it seemed they had better times than their amateur contemporaries.
