Triathlon Race Nutrition Products Compared: Labels, Carbs and Sodium (2026)

Pick fuels that deliver the carbohydrate you can absorb, decide whether sodium is built in or added separately, avoid your allergens, and match cost and format to your race length and gut. Then rehearse them in training — never trial a new product on race day.

The table below lists published per-serving numbers for popular products so you can compare like with like. It's a research-based comparison of labels, not a taste or performance test, and it deliberately gives no universal grams-per-hour target — that's individual. For planning your own ranges, use the Race Nutrition Calculator or, for long course, the Ironman Fueling Planner.

Five columns decide most choices:

1. Carbs per serving — the headline number. A 25 g gel and a 40 g gel are not interchangeable; higher-carb products mean carrying fewer items on long course.
2. Sodium per serving — some brands (Maurten, Precision Fuel, SiS Beta) put little or no sodium in their carbs and sell electrolytes separately, so you plan sodium independently. Others bundle it.
3. Caffeine — useful late in a race, but dose it deliberately and know your tolerance.
4. Allergens — a summary only; always read the current label if you have an allergy.
5. Cost per serving — matters most when you need many servings for a long race.

For the science of how much your gut can take, see gut training; for gels specifically, energy gels; for electrolytes, electrolytes explained.

Carbohydrate delivery is the primary job of race fuel, and products vary widely:

• ~20–25 g (GU, Gatorade Endurance gel, Maurten Gel 100): easy to dose in small increments; you carry more of them.
• ~30–40 g (Precision PF 30, SiS Beta Fuel gel): fewer items for the same carbs — handy on long course.
• ~79–90 g (Maurten Drink Mix 320, PF 90 flask): concentrated systems that deliver a big share of your hourly carbs from one bottle or flask.

Higher isn't automatically better — it depends on how much your gut absorbs, which you build with training. The point of the comparison is to plan the number of items you need, not to hit a universal target.

Sodium is where labels surprise people. Several premium gels are carbs-only by design (0 mg sodium), because the brand sells sodium as a separate electrolyte product. That's not a flaw — it just means you must plan sodium independently (tablets, drink mix or capsules) rather than assuming your gel covers it. Other products (Gatorade Endurance, Tailwind, GU) include meaningful sodium.

Caffeine appears in some flavours/versions and not others. It can help perception of effort late in a race, but it's easy to over-caffeinate across a long day — decide a total in advance and choose caffeinated vs non-caffeinated versions deliberately. There is no one-size dose here; individual sensitivity varies a lot.

For hot or long races, a dedicated electrolyte like a high-sodium tablet lets you separate hydration/sodium from carbs entirely.

Different races reward different fuel:

• Sprint (under ~1.5 h): you can largely race on your pre-race meal plus water or a sports drink; a single gel is often plenty.
• Olympic (2–3 h): a drink mix plus a gel or two; simple and light.
• 70.3 (4–6 h): a repeatable hourly plan of gels/chews plus fluid and planned sodium; higher-carb gels reduce what you carry.
• Ironman (8–15 h): a concentrated carb system plus separate sodium, and often some real food for variety — see real food vs gels and Ironman nutrition.

One more practical filter: what's on your course. Many Ironman races serve a specific brand (often Gatorade Endurance), so training with it — or planning to carry your own — avoids surprises.

This is a comparison of published specifications, and it has honest limits:

• It is not an intake prescription. How many grams of carbohydrate or sodium you need per hour is individual and depends on body size, sweat rate, intensity, heat and gut tolerance. Build that with gut training and, for medical conditions, get professional advice.
• Labels and prices change. Nutrition numbers come from manufacturer labels and cost figures were checked in August 2026; verify the current label, especially for allergens.
• It's not a taste or performance test. Products that look similar on paper can feel very different in your stomach — rehearse them in training.

Used this way — to compare numbers and plan quantities — the table is a buying and planning aid, not a substitute for your own rehearsal.

The following examples show why package size and flavor belong beside the brand name. They are not endorsements. The official manufacturer pages linked in the sources are the reference points for the stated values; local wrappers remain the final check.

Maurten Gel 100 lists 25 g carbohydrate and 20 mg sodium per sachet; its Gel 100 Caf 100 variant adds 100 mg caffeine. SiS Beta Fuel + Electrolyte Gel lists 40 g carbohydrate and 200 mg sodium per 60 ml serving, while the plain Beta Fuel gel is a different product and should not be assigned that sodium figure. Precision Fuel PF 30 Gel supplies 30 g carbohydrate and is designed without electrolytes; the caffeinated version is a separate product. GU Original Gel lists about 21–23 g carbohydrate and 60–125 mg sodium across the range, with caffeine varying by flavor. Check the individual packet rather than treating the range as one recipe.

CLIF BLOKS Strawberry lists 24 g carbohydrate per three-piece serving and its current US product page describes some flavors as caffeinated or higher in sodium. Gatorade Endurance Energy Gel Vanilla lists 20 g carbohydrate and 100 mg sodium; other flavors may have different caffeine or sodium values. Maurten Drink Mix 320 supplies 80 g carbohydrate when one sachet is mixed with 500 ml water, which is the whole prepared bottle, not a single sip. Tailwind Endurance Fuel's standard single packet is two scoops and lists 50 g carbohydrate and 620 mg sodium; the one-scoop amount is half of that. Check flavor-specific caffeine on Tailwind's current label.

These label differences are enough to change a plan. A “40 g gel” in the table is not necessarily the same formula as a 40 g drink mix serving; a caffeinated version is not interchangeable with an unflavored one; and salt and sodium figures use different units. The point of this table is to make those questions visible before you pack.

A product comparison can blur three needs that should be planned separately. Carbohydrate is fuel. Fluid intake responds to access, conditions, thirst, body size and individual sweat losses. Sodium content is one part of electrolyte replacement for some athletes and situations. A product that combines all three may be convenient, but it does not tell you how much fluid or sodium you personally need.

For example, a drink mix may contain a high amount of carbohydrate in a bottle while a separate electrolyte drink contains little or no carbohydrate. That can be useful if it matches a practiced strategy, but it is not a reason to drink the bottle faster than planned. A concentrated drink may need to be carried with separate water depending on its instructions and the athlete's plan. Conversely, a low-carbohydrate electrolyte drink does not count as a gel or meal replacement. Write down the carbohydrate, fluid volume and sodium contributed by each item so one product is not accidentally counted twice.

No product label can account for all of an athlete's race conditions. Aid station spacing, bottle handoffs, heat, pacing, swim access and stomach comfort all affect what is practical. Use the race guide to understand course supply and the products' own directions to mix them correctly. For an individualized fluid and sodium plan, consult a qualified sports dietitian or clinician; do not derive a medical plan from a comparison table.

A current product price is specific to a market and day. A pack of eight sold at a discount may appear cheaper than a twelve-pack at full price, but package count alone does not compare fueling amounts. To normalize cost, note the price including delivery, divide by labelled servings, and then divide by carbohydrate grams per serving. This gives a rough cost per gram of carbohydrate for that listing. It is a shopping aid, not a measure of product quality or how well you tolerate it.

For a drink mix, count how many bottles one pouch makes at the stated concentration and include any extra bottle or flask you need. For a product that supplies sodium separately, include the cost of that item only if your plan actually calls for it. Avoid treating the manufacturer's intended serving frequency as your personal dose. A product with a larger serving may look inexpensive per packet but be expensive per carbohydrate gram, while buying a bulk pack may make sense only if you will use it before its best-before date and have already tested the flavor.

Prices and shipping vary across the US, Europe and other markets, and sale prices can change between article updates. For an accurate comparison, check the retailer at the time you buy and use the same currency, pack basis and delivery assumptions for each candidate. This page deliberately avoids a “cheapest” badge that could become wrong as soon as prices change.

Ingredient lists can differ between flavors in the same brand. A range-wide description such as vegan or gluten-free is not a substitute for reading the specific wrapper when you have an allergy, coeliac disease, or another medically necessary restriction. Verify the current ingredients and allergen statement on the package and with the manufacturer. If the information is unclear, choose a product with confirmed labeling rather than guessing from a previous version or a retailer's short description.

Athletes subject to anti-doping rules may also check whether the exact product or batch appears in a recognized third-party testing program. Certification can reduce some contamination uncertainty, but it does not prove that a product is needed, effective, safe for every individual, or guaranteed free of every prohibited substance. Product certification status can change; verify the current mark and batch information through the certifier or manufacturer. This comparison does not certify or independently test any item.

Caffeine deserves its own review. Record the milligrams on each caffeinated serving and count coffee, tea and other sources used that day. Do not assume that a lower-caffeine packet is appropriate for a child, a pregnant athlete, someone sensitive to caffeine, or someone taking interacting medication. A sports nutrition product is still a food product with ingredients and a dose; use clinical advice when the personal risk is not clear.

Use the same questions for each candidate instead of choosing based on branding. First, write the carbohydrate amount in the serving you will actually carry. Second, note whether it is a gel, chew, powder or ready-to-drink format and where you would consume it. Third, record sodium and caffeine only from the exact flavor label. Fourth, check ingredients, allergens, the amount of water required and any race-day mixing rule. Fifth, calculate cost per usable serving from a current local listing if price matters.

Now compare each candidate with a session that resembles your race. Did the flavor remain tolerable? Could you open and swallow it at the intended effort? Did you have appropriate access to water? Did the bottle fit your bike setup and the event's rules? If you change the brand, carbohydrate amount, caffeine or concentration, treat that as a new variable and rehearse it rather than making several changes at once. This is a practical comparison method, not a guarantee against gastrointestinal problems.

The best option for one athlete may be a familiar, modest serving from an inexpensive product; another athlete may need a different texture or carrying format. If no tested option feels tolerable, or if symptoms repeatedly limit training, work with a sports dietitian or clinician instead of continuing to add supplements. The comparison should narrow the questions you need to answer, not tell you what your body must tolerate.

A short calculation can show what a product format changes without deciding how much an athlete should consume. Suppose you are comparing two ways to carry 80 g of carbohydrate for a training simulation. One Maurten Drink Mix 320 sachet provides 80 g when mixed with the specified 500 ml of water. Two SiS Beta Fuel + Electrolyte Gel servings provide 80 g from two 40 g gels. The carbohydrate total is the same; the delivery is not. One is a prepared bottle with a fixed mixing volume, and the other is two separate packets that do not themselves supply that bottle of fluid.

The gel labels also list 200 mg sodium per serving, so two gels contribute 400 mg sodium in total. Do not assume that the drink mix has the same sodium amount: check the current product label for its own serving and prepared volume. This arithmetic does not mean either combination is appropriate for a given race or athlete. It only compares what is printed on the named package sizes. A real plan must account for the event duration, drinking access, other food and drink, personal tolerance, and any clinician advice.

You can use the same method for a smaller comparison. Two 30 g PF 30 gels provide 60 g carbohydrate according to the product serving; three 20 g Gatorade Endurance Vanilla gels also total 60 g. Check the sodium and caffeine listed for the exact variants before treating them as substitutes. For chews, multiply the label's grams per serving by the number of servings you will carry, not the number of pieces you happen to eat. Write the result down so a “packet” does not silently change from one product to another.

When comparing a powdered mix, distinguish the amount of carbohydrate in the whole prepared bottle from what you would actually drink in one part of the course. If you pour a bottle into a flask or share it across several hours, calculate from the consumed fraction. Do not mix it at a stronger concentration unless the manufacturer directions and your practiced plan support that. The product can be convenient in one format but awkward in another, so finish the comparison with the practical questions: where will it fit, when can you access water, can you open it, and what will you do with the wrapper?

This kind of equivalency arithmetic is most useful when replacing a product that is unavailable or when deciding what to buy for a training rehearsal. It is not a nutrition target. Keep carbohydrate totals separate from sodium and fluid totals, and do not use a mathematical equivalence to infer equal absorption, comfort, safety, or performance.

Nutrition panels compare only what the label defines as a serving. Before comparing products, check the serving size, carbohydrate per serving, sodium per serving, caffeine amount if present, and the number of servings in the container. A bottle of drink mix may contain more than one serving, while a gel sachet may be labeled as one. Compare equivalent units, then consider how much you would realistically carry and consume.

Read the ingredient and allergen statements on the exact item you intend to use. Flavours within one product family can differ, and formulas may change across markets. Look for ingredients you need to avoid and check whether a product contains caffeine, sugar alcohols, or another component relevant to your individual tolerance. If you have an allergy, medication question, medical condition, or a history of significant digestive symptoms, ask an appropriately qualified clinician or sports dietitian rather than relying on a retailer’s summary.

A label cannot tell you whether a product will be comfortable during your particular swim, ride, or run. Try a small, planned use in training when appropriate, note the conditions and amount, and do not test multiple new products on race day. The gut-training guide covers practice; this page focuses on comparing the package information.
