I’m just going by Bolt stating in an interview the the furthest he ever ran in training was 600 early in the year. He also said he does not like to jog because it makes his calves tight.
However, there are still coaches who do the long runs with succesful athletes- Brooks Johnson, Tellez, etc. I personally do not think it is detrimental to do early in the year, redundent yes.
Regardless of what Bolt and Mills have said they may still do the long runs. We know for a fact Mills studied Bud Winter. Winter did the long run thing to start the year. We know both Franno and Mills training is basic and old school compared to more scientific approaches.
