4X5 Strict Weighted Pullups 10kg (10s rest)

WOD
For time:
110 pound/50kg Thruster, 15 reps
Run 200 meters
95 pound/42.5kg Thruster, 20 reps
Run 400 meters
65 pound/30kg Thruster, 30 reps
Run 800 meters
I expected to do the 800m run much faster, but my lower back got really tight after the first round and I felt awful. It's been a while since something like this has happened in a wod.
