A fuelling plan should be a read, not a rule

Athletes get drilled to follow a sheet and never get drilled to change it when conditions do.

Handing an athlete a fixed schedule of what to drink and when feels like good practice. It is written down, it is individual, it came from a test. Then the day is fifteen degrees hotter than the day the plan was built on, and the athlete follows the sheet, because following the sheet is what they were taught to do.

Compliance is easy to coach. Judgement is not, and so most programmes quietly settle for the easy one. The result is an athlete who executes beautifully in the conditions the plan assumed and has no idea what to do in any other conditions, which describes most competition days.

The deeper problem is that the plan replaces the athlete's own attention. Somebody who drinks to a whistle for three seasons stops noticing what they feel like, because noticing has been made irrelevant. Then they go to a tournament without staff, or move clubs, or turn thirty and their body changes, and the internal instrument they never developed is not there.

Coaching the read is slower but it is not complicated. Start by making the athlete predict. Before the session, ask what today will need and why, and get an actual number. After the session, compare. Do that for a month and people begin building a private model of themselves that survives any change of staff.

Then rehearse the exceptions on purpose. Train once in the heat of the afternoon and have them plan for it. Train once after a long journey, once in a cold wind that hides the sweat loss entirely, once on a day with two sessions in it. Each of those is a different read and none of them is covered by the sheet.

There is a boundary here and it is worth naming. Reads work for adjustments, not for the fundamentals. Nobody should be reasoning their way to a decision about whether to drink at all in serious heat, and juniors especially need firm rules before they get discretion, in the same way you teach a fixed technical model before you allow variation. The mistake is leaving everyone at the rules stage forever because it is tidier for the staff.

A plan the athlete cannot modify is a plan that belongs to you. It should belong to them, and the test of that is whether it still works on a day you are not there.
