Similar to what ebomb said if i was doing the circiut I’d have a good warm up jog( in doing so I’d take the other 100m jogs out), add set rep ranges for the squat and deadlift (since your already working your legs) but keep failure sets for OH press and push ups.
Another idea is to get 2 sand bags and perform the 100m sprints between them.
IMO that would really rev up intensity.
