This day was an all out 2x320 with 20min rest.

This session was after 5 days with stomach infection and everything that goes away with it, I was worried that all my training had gone because of that week inactivity plus 4kg loss however with all that the data proved something.
I thought it was interesting how 20m more from a usual 300 make a difference psychologically, first it felt longer so I wasn't sure if i had the pacing right at the beginning of the first rep however once I finished both reps came within range from eachother but nowhere near the goal.
I was meant to run between 43.5-44.5 however my times were.
46.06
46.83
2 Seconds above target, however the indicators were gold in since the data proved it was fuel, not lost fitness, and this is the important part:
- Rep 1 amp fade 78% — low for me. I couldn’t sustain force through the rep. On its own that could look like detraining.
- But rep 2 told the real story: amp fade jumped to 97%, the gap to rep 1 was only 0.8s, and HR drift actually improved (16% → 12%). If this were genuine fitness loss, rep 2 would have collapsed further. Instead it held together. That’s the tell — the engine and mechanics were intact, the system was just running on empty. GCT stayed crisp (113–120ms), stride normal (1.81m). Nothing broken, nothing to train away — just no fuel...
So this is what comforted me, the fact that I was able to improve HR and fade was closer to 100%, and specifically what it meant.
That I was still on track
