Saturday. Same bike, same route I use to test everything. MotoSupport strapped on under my jacket — three memory-alloy stays down the back, dual spring strips on the sides, 360° compression holding everything in place. Took 20 seconds to put on. Forgot about it within 10 minutes.
Minute 30: Normal riding. Comfortable.
Minute 50: Normally I'd be pre-aware by now. A subtle tension in my lower back telling me the hour mark is coming. I checked in with my body. Nothing. No tension. No pre-ache.
Hour 1: This is the line. The point where every ride for three years has started deteriorating. I braced myself out of habit. The pain didn't come.
Hour 1:30: Still upright. Still riding the way I was at minute five. My shoulders were down. My back was straight. Not because I was forcing it — because something was holding it for me. The mental energy I normally spend thinking "sit up, shoulders back" wasn't needed.
Hour 2: I stopped at a petrol station. Not because I needed to, but because I wanted to process what was happening. Two hours. No slump. No pain. No fade. I got off the bike and realised my back felt exactly the same as when I got on.
Hour 3: I kept riding. Three hours — something I hadn't done without pain in years. Pulled into my driveway, got off the bike, and walked inside like I'd been sitting on a sofa.
