Training loads and rest is a set of peaks and troughs.
One side effect of resting for a week is to go to the bottom of a trough. It's the subsequent runs which bring you back to the peak.
Imagine a training cycle like someone doing the long jump. That's a pause, an acceleration and then a sudden big effort, then stop. A training cycle is the same.
You tried a sudden big effort from a position of stop.
If you had run a couple of short runs first over the course of a few days you would have been primed for the bigger effort.
That's how 'peaking' works. You have to climb back up the mountain first before you get there.
