Fueling Before and After Training
A decision-first way to plan familiar food around duration, intensity, start time and recovery demands.
01
Five questions before choosing food
Start with session duration, intensity, start time, time since the last meal and time until the next demanding session. The answer is often ordinary food, not a special product.
Gut comfort matters. A smaller, familiar and lower-fat or lower-fibre option can be easier close to training, while a normal meal fits when there is more digestion time.
02
During-session carbohydrate has context
Easy or short sessions often need no dedicated carbohydrate. For harder work lasting 60–150 minutes, guidance commonly discusses 30–60 g/hour. For longer endurance work, higher ranges require practiced multiple-carbohydrate strategies and are not beginner defaults.
Try event nutrition in training rather than for the first time on race day. The tool does not prescribe fluid or electrolytes because climate, sweat loss and medical context require more information.
03
Recovery is not a five-minute window
When an ordinary meal follows soon, it can provide carbohydrate and protein without a shake. A protein context of 0.25–0.40 g/kg can help size that meal without implying a hard threshold.
Rapid carbohydrate replenishment matters more when another hard session follows within about eight hours. After an isolated recreational session, the rest of the day matters more than an alarm clock.
04
Escalate complex cases
Diabetes treatment, recurrent gastrointestinal symptoms, heat exposure, clinical diets and endurance competition deserve individual planning. General ranges should never override symptoms or prescribed care.
Starting template by session
| Session | Starting point |
|---|---|
| Under 60 min, easy/moderate | Ordinary meals and fluids are often sufficient |
| 60–150 min, moderate/hard | Consider familiar pre-session carbohydrate; 30–60 g/hour may be relevant |
| Over 150 min or competition | Use a practised sport-specific plan |
| Two hard sessions close together | Recovery timing becomes more relevant |
Fictional worked example
Put the arithmetic in view
- A 70 kg adult has a 90-minute moderate-to-hard ride at 18:00 and last ate at 13:00.
- A familiar snack or meal at 16:00 leaves two hours to digest. At 30 g/hour during the ride, 1.5 × 30 = 45 g carbohydrate.
- Post-session protein context is 70 × 0.25–0.40 = 17.5–28 g; an ordinary dinner can cover this.
Questions readers ask
FAQ
When is during-session carbohydrate worth practising?
It becomes more relevant as a session gets longer or more demanding. Practise any event-fuelling plan during training, start within a tolerable range and do not assume the highest displayed amount is automatically better.
What counts as a short turnaround between sessions?
This guide uses another demanding session within about eight hours as the trigger for rapid-refuelling context. It is an interface rule, not a biological cliff or a guarantee that a protocol is necessary.
Why does the planner not calculate water or sodium?
Fluid and sodium needs depend on climate, sweat loss, session conditions, acclimatisation, medicines and health context. The current inputs are not enough to produce an individual dose responsibly.
How can I test gut tolerance before an event?
Use familiar training sessions, change one food or drink variable at a time and record the amount, timing and symptoms. Persistent or severe gastrointestinal symptoms need professional assessment.
Can I use the same template for strength and endurance sessions?
Not automatically. Duration, intensity, recent meals and recovery time matter more than the activity label alone. A short strength session and a long ride can produce very different decisions.
