Mixing Split Run Types

I’ve got the book, now have to read it…

With split runs and special endurance, I have an athlete who can only do about 210m of which one can be 120 - 150 and a shorter one of 60 - 90, due to a back issue.

Would it be better to stick that sort of rep as 2 separate runs or if he can manage it do say 2 x 60 + 60 +60?

what sort of back issue? What aggrivates it? Higher speed or going farther?
