Felt good and easy throughout. A clear step up from the last Prowl on 260312 — +10 min duration, +1.7 km distance, -4 bpm avg HR, -1:15/km faster pace. More output at lower cardiac cost. That's aerobic adaptation doing its job. Last session was a grind under work stress — sluggish, power-walking, barely holding Zone 2. Today was the opposite: smooth, conversational intensity, no mental resistance. The difference between forcing it and flowing with it. No neurological symptoms before, during, or after. Clean session.
