That depends on whent the sprints and ME work was done.
I recommend keeping some sprints in your program at all times. Early in a cycle that can be with a sprint focus; later, for speed maintenance. It’s good to think of sprints as “base” training for speed. It’s something you always want to either develop or maintain.
If the sprints in the skimo program repeat from the Foote program, you could progress them as required. This can be done by either increasing the number of reps or the length of the interval (in increments of ~5 seconds).
