Common questions
What is the festival hydration planner?
It turns weight, extra for heat or exercise into a session total you can read in one sitting.
Is this a coaching plan?
No. It is arithmetic for a week you already intended.
What if I am injured or unwell?
Stop and get proper advice. A product of two boxes is not rehab.
