Lower intensity without reload weeks

On brink of commencing a half marathon plan having previously used runna for marathon training earlier this year. Before I do so I am trying to reflect on aspects of the app which worked well for me before and those that worked less well.

One of the things I didnt think suited me and my training that well was the structure of having de load weeks. Is it possible to structure your plan so its slightly lower intensity but without de load weeks or is this how all the plans are structured?

When I did a run keeper plan back in the day that didn't have de load weeks and I think continuous building at slightly lower intensity suited me better.
