Anyone has any ideas, scientific claims, personal anecdotes or just some good bro-science on the subject?
In short, the idea is to do all your runs in a low puls zone and run pretty high mileage. For me I think it was something like 145-150 bpm which would result in a rather slow pace. You do this for a number of months during of season and then start with speed work in spring.
From what I have read some some people seem to have gotten great results and as always some people did not.
Currently writing on my phone so no links but a quick search on long slow distance or long steady distance brings up a lot.
