Long-run fuel rehearsal is the quiet practice that makes race-day eating feel ordinary. Over four weeks, Australian runners can test a simple combination of carbohydrate, fluid and timing on relaxed long outings, then keep only what sits comfortably. The purpose is not to copy a professional plan; it is to learn how your own stomach and energy respond while the effort remains controlled.
long-run fuel rehearsal: Start with a baseline
Choose a long run you already complete comfortably and note the start time, weather, distance and what you ate beforehand. Do not start a fuelling experiment when you are ill, dehydrated or returning from injury. Sports Dietitians Australia and the Australian Institute of Sport provide general sport-nutrition resources, but individual needs vary with body size, medical history, medication and training load.

Keep your familiar pre-run meal and carry the fluid you normally tolerate. If the run lasts about an hour or less, many runners can rely on ordinary meals and drink to thirst; longer sessions may benefit from planned carbohydrate. Record when hunger, thirst or a drop in concentration appears. Those observations are more useful than a rigid rule borrowed from someone else.
Use small sips rather than waiting until you feel desperate. In warm or humid conditions, move the run earlier, shorten it or add a safe refill point. Heat changes sweat loss, so avoid promising a universal bottle size or sodium dose.
Week two: test one carbohydrate option
On a similar long run, introduce one familiar carbohydrate source, such as a gel, sports drink or soft food you have already eaten safely. Take a small amount before you feel empty, then continue at an easy effort. Do not combine several new products. Check the label for serving size and practise opening the package while moving.
If your stomach feels unsettled, slow down, stop the experiment and return to the baseline on the next outing. A food diary can reveal whether the issue was the product, concentration, heat, pace or a crowded pre-run meal.

Repeat the option that felt best and practise the timing you might use in a race. Carry the same bottles, belt or pockets you expect to use, but keep the route safe and familiar. If you will rely on aid stations, check the organiser’s published plan rather than assuming a brand or flavour. Fueling is also a pacing skill: taking a brief walk break can make swallowing easier and preserve an even effort.
Week four: keep the simplest version
Run the final rehearsal without adding a new variable. Compare your notes from all four weeks and choose the smallest routine that kept energy steady and your stomach calm. The best plan may be less food than you expected, or it may require more frequent small servings. Keep the approach flexible for weather and course changes.
Connect fuelling to training
Place rehearsals inside a balanced week with easy runs, one purposeful session and a gradual long-run progression. Our RunHQ progressive distance plan shows how to increase work without turning every outing into a test. For device comparisons, see runningwatches.com.au; a watch can log duration, but it cannot decide what your body needs.
