You do not need to buy biscuits specifically for a 5k: Sports Dietitians Australia says regular meals and snacks can meet the needs of people exercising a couple of times a week, while the NHS suggests a light carbohydrate-based snack 1–2 hours before a run. If you want a familiar biscuit, compare the portion you would eat: Ocado lists 7.2 g carbohydrate and 1.7 g fat per McVitie’s Ginger Nut, against 9.3 g and 3.1 g per Original Digestive. Those are food-label figures, not evidence that either biscuit improves running performance; check the current pack for ingredients and allergens.
If you are deciding whether to eat before running, consider what you have already eaten and which familiar foods sit comfortably. The NHS suggests a light carbohydrate-based snack 1–2 hours before a run, with a banana or toast as examples.
If you would like a biscuit, compare the actual per-biscuit portion, carbohydrate, fat and ingredients. A biscuit’s name does not establish how it will feel to eat before a run.
Check the exact pack before choosing. For example, the M&S Made Without Stem Ginger Snaps listing describes the biscuits as gluten-free but also lists milk and nut and peanut precautions.
Start with whether you want a snack at all; if you choose a biscuit, compare the portion and ingredients rather than treating ginger nuts or digestives as specialist running food.
| Priority | What to check | Your needs |
|---|---|---|
| Whether to eat | Consider your usual meals and the time until your run. The NHS suggests a light carbohydrate-based snack 1–2 hours beforehand and gives banana and toast as examples. | I may prefer an ordinary meal or a familiar non-biscuit snack rather than buying biscuits specifically for a 5k. |
| Biscuit portion | Compare carbohydrate and fat per biscuit, then consider how many you would eat. Ocado lists 7.2 g carbohydrate and 1.7 g fat for a McVitie’s Ginger Nut, versus 9.3 g and 3.1 g for its Original Digestive; these are different portions. | If I choose between these biscuits, I want to compare what my intended portion contains, not assume their names indicate a running benefit. |
| Familiarity | Try food and snack timing during training. Sports Dietitians Australia advises choosing familiar, well-tolerated food rather than experimenting on competition day. | Before an important run, I would rather eat something I already know suits me. |
| Ingredients | Read the current pack’s ingredient and precautionary statements. Ocado’s listings show wheat ingredients in the cited McVitie’s biscuits; its M&S Made Without Stem Ginger Snaps listing describes a gluten-free biscuit that contains milk and carries nut and peanut warnings. | If I need to avoid an ingredient, the exact product’s label matters more than whether it is called a ginger nut, digestive or gluten-free biscuit. |
“Digestive” and ginger flavour do not establish easier digestion or better 5k performance. The cited product listings describe ingredients and nutrition, not running outcomes.
Decide whether you want a snack, then choose a familiar food and a portion you have tried before running.

If you prefer a gingerbread-flavoured chocolate digestive, compare the portion you intend to eat with a plain biscuit using the pack’s nutrition information. The chocolate coating makes this a different choice from a plain digestive.

For a ginger-flavoured biscuit rather than a digestive, check the pack’s carbohydrate and fat figures against the number of biscuits you plan to eat. Its ginger flavour alone does not establish a pre-run benefit.
No image available
If you are considering a sugar-free digestive, check its ingredients, any sweetener warnings and the portion’s nutrition information on the pack. “Sugar free” does not establish how the biscuit will suit you before running.
No biscuit is specified as necessary in the cited guidance. The NHS suggests a light carbohydrate-based snack 1–2 hours before a run, giving a banana or toast as examples; consider your usual eating and what you tolerate.
Try unfamiliar snacks and timings during training instead. Sports Dietitians Australia advises choosing familiar, well-tolerated food before exercise rather than experimenting on competition day.
Check the current pack before eating. Tesco cautions that formulations can change, and the allergen information must apply to the exact biscuit you choose.
