The 05:00 Rule
The day belongs to whoever gets up first.
There is one hour nobody can book. It comes before the inbox wakes, before the car arrives, before anyone has an opinion about your day.
The run is not about fitness. It's about deciding, before anyone else gets a vote, what kind of day it will be.
That's why the quarter-zip exists. It's light and warm, and it's still fine for the lobby on the way back. You run, shower, and the day starts on your terms.
