Nutrition & Fueling for Training and Racing

Build your plan around the work ahead. Learn what your products provide, choose a practiced fueling schedule, and keep carbohydrate, fluid, sodium, and caffeine totals separate.

The science behind your choices

Established role

Carbohydrate supplies usable fuel

During prolonged exercise, carbohydrate intake helps maintain blood glucose and carbohydrate use. Gels, chews, maple syrup, and drink mixes are delivery formats. The serving and tolerated intake matter more than the format alone.

Individualize intake

Fluid and sodium have different jobs

Fluid replaces water losses. Sodium contributes to electrolyte replacement. Drinking more than you need risks low blood sodium, even when you take salt. Your plan needs individual fluid decisions, not a universal tablet schedule.

Food first

Protein supports repair

Protein foods and supplements contribute amino acids for recovery. Total meals, adequate energy, and the protein amount in the serving matter. A recovery product adds convenience rather than replacing your entire diet.

Different evidence levels

Caffeine is optional. Ketones are emerging.

Caffeine has established performance uses in selected adult settings. Ketone supplements have emerging or mixed support. Neither replaces carbohydrate or guarantees a faster race. Read the evidence for the ingredient and the exact use.

Start with time, then refine

Established duration-based starting points
Your session Carbohydrate during exercise How to apply it
Under 45 minutes Usually unnecessary Arrive fed. Cover warm-up and waiting time with normal meals or a familiar snack.
Hard effort lasting 45–75 minutes Small amounts, including a carbohydrate mouth rinse Optional support for a sustained hard effort. An entire gel schedule is unnecessary.
About 1–2.5 hours 30–60 g per hour Start with a tolerated amount. Count drinks, gels, chews, and food together.
Longer than 2.5–3 hours Build toward 60–90 g per hour when appropriate Use mixed carbohydrate sources at higher rates and practice. A new athlete should not jump straight to 90 g per hour.

These duration bands overlap. Effort, prior meals, gut tolerance, and your training change the best choice. A 50-minute 10K and a 90-minute 10K need different strategies.
