You can have:
Thur: GPP conditioning (prowler, sandbag carries, sled, etc)
I do hill sprints twice a week, Tues and Saturday.
Saturday is conditioning day just like yours, loads of carries,prowler push and pull, kettlebells and at the end, 6 to 8 rounds of sprints in one of hell of a bitchy steep hill.
My week usually looks like this:
Tues: Chest +Shoulders and Sprints
Weds: DLs +Hams
Fri: Back+ more legs
Sat: Conditioning + hill sprints
