Sounds like a solid plan – collect as much data as you can: split times, GPS velocity, heart‑rate variability, and even ground‑reaction forces if you can get them. Run a baseline block, log everything, then use a regression model to see which variables most strongly correlate with your fastest splits. Once you know the levers, tweak volume, intensity, and recovery in small increments and keep re‑testing. Just remember: incremental changes, rigorous tracking, and consistent recovery are the keys to shaving that second.

That’s the right mindset. Start with a clean baseline, log everything, and keep the adjustments tight. Once you see a change in the data, push the next variable. Keep it structured, and you’ll trim that second. Let's do it.

Good. Set up the data capture first, then run the block. Keep the logs clean, the metrics tight, and the adjustments precise. We'll track everything, analyze, and iterate. Let's shave that second.

Sounds like a solid plan. Once the data is in, we’ll run the numbers, spot the strongest levers, and tweak systematically. Keep it tight, keep it focused, and we’ll shave that second. Let's start.
