Best Cycling Drink Mixes: Hydration and Fuel Compared

Hydration vs. Fueling: Two Different Problems

Hydration mixes prioritize sodium and electrolytes with minimal calories. Their job is to replace what you lose in sweat and drive fluid absorption. Examples: Nuun Sport, SiS GO Hydro, LMNT, Precision Hydration.

Fuel mixes prioritize carbohydrate delivery with some electrolytes. Their job is to get 60–90g of carbs per hour into your bloodstream through your bottles. Examples: Maurten Drink Mix 320, Tailwind Endurance Fuel, SiS Beta Fuel.

Many cyclists use one bottle of each on long rides: one for fuel, one for hydration. Alternatively, fuel with gels and use both bottles for hydration.

Quick Comparison

Fuel Mixes

Maurten Drink Mix 320 — Editor's Pick

Maurten's hydrogel technology delivers 79g of carbs per 500ml bottle at a 1:0.8 glucose-to-fructose ratio — the highest carb density of any drink mix with near-zero GI distress. The Drink Mix 160 offers 39g per 500ml for lower-intensity rides.

At $4.50 / €4.15 per serving, it is the most expensive option. But for race day, the ability to get 79g of dual-transport carbs through a single bottle is unmatched. Used extensively in the World Tour peloton.

• Pros: 79g carbs per bottle, 1:0.8 ratio, hydrogel for GI tolerance, no flavor fatigue
• Cons: $4.50 / €4.15/serve, bland taste, limited flavors, settles if not shaken

SiS Beta Fuel

SiS's answer to Maurten: 80g of carbs per bottle with a 1:0.8 ratio, 250mg sodium, and a lower price at $3.75 / €3.45. It dissolves more easily than Maurten and has actual flavor options.

Used by Team INEOS and widely available. The main downside versus Maurten is that it does not use hydrogel technology, so some riders with sensitive stomachs report more GI issues at very high intake rates.

• Pros: 80g carbs, 1:0.8 ratio, better taste than Maurten, more affordable
• Cons: No hydrogel tech, more GI complaints at 90g+/hr, very sweet

Tailwind Endurance Fuel

Tailwind is the all-in-one solution: carbs, electrolytes, and calories in a single mix. At 25g carbs and 303mg sodium per scoop ($1.15 / €1.05), it is the most cost-effective way to fuel and hydrate simultaneously.

The community loves Tailwind for simplicity. Mix 3 scoops per bottle for 75g carbs and 909mg sodium — and you do not need to carry separate gels or electrolytes. Ultra-distance cyclists and gravel riders especially favor this approach.

The downside: using dextrose and sucrose rather than an optimized 2:1 maltodextrin:fructose ratio. For moderate intake rates (60g/hr), this is fine. For 90g+/hr racing, a true 2:1 formula is better absorbed.

• Pros: All-in-one fuel + hydration, $1.15 / €1.05/serve, high sodium, mild taste, ultra-community favorite
• Cons: Not optimized glucose:fructose ratio, concentrated solutions can be too sweet, no hydrogel

Skratch Labs Sport Hydration Mix

Skratch occupies a middle ground: 21g of carbs and 380mg of sodium per serving. It is not a high-carb fuel mix and not a pure electrolyte tablet. It is a "do a bit of everything" drink that many recreational cyclists love for its real fruit flavoring and gentle stomach feel.

The sodium content (380mg) is higher than most competitors in this category, making it a reasonable choice for riders who sweat heavily but do not want separate fuel and hydration bottles.

• Pros: Great taste (real fruit), 380mg sodium, gentle on stomach, EF team sponsor
• Cons: Only 21g carbs (not enough for high-intensity fueling), $1.25 / €1.15/serve is mid-range

Hydration Mixes

Precision Hydration PH 1500 — Editor's Pick

Precision Hydration is built on one idea: serious athletes under-dose sodium. The PH 1500 delivers 1,500mg of sodium per liter with virtually zero calories. For heavy sweaters (those losing 1,000–2,000mg of sodium per hour), this is the only product that actually replaces what you lose.

They also offer PH 500 and PH 1000 for lighter sweaters. The Precision Hydration sweat test (available online or in-person) helps you determine your sweat sodium concentration and pick the right strength.

• Pros: 1,500mg sodium (highest available), science-backed sweat testing, zero calories, available as effervescent tablets or powder
• Cons: $2.50 / €2.30/serve, no carbs (need separate fuel), mild salty taste

Nuun Sport

Nuun's effervescent tablets drop into a bottle and dissolve in 2 minutes. At $0.70 / €0.65 per tablet with 300mg sodium and only 4g of carbs (15 calories), they are the cheapest and most convenient hydration option.

The trade-off: 300mg of sodium is moderate. For hot conditions or heavy sweaters, you may need 2 tablets per bottle. The Nuun Endurance variant bumps sodium to 380mg and adds more carbs.

• Pros: $0.70 / €0.65/serve, convenient tablets, 300mg sodium, light clean taste, widely available
• Cons: Moderate sodium (may need double dose), artificial sweetener, minimal carbs

LMNT

LMNT delivers 1,000mg sodium, 200mg potassium, and 60mg magnesium per packet with zero sugar and zero calories. It has become enormously popular through podcast sponsorships and the keto/carnivore community.

For cyclists, it works well as a pre-ride or recovery electrolyte, but the lack of carbs means it is not a standalone ride fuel. At $1.75 / €1.60 per packet it is pricier than Nuun but cheaper than Precision Hydration, with a similar high-sodium profile.

• Pros: 1,000mg sodium, zero calories, good taste (especially citrus salt and watermelon salt), clean ingredients
• Cons: $1.75 / €1.60/serve, no carbs, aggressive marketing claims, not cycling-specific

How to Choose

For racing (90g+ carbs/hour): Use a fuel mix (Maurten 320 or SiS Beta Fuel) in one bottle and plain water or an electrolyte tablet in the second.

For training rides (60–80g/hour): Tailwind or Skratch in both bottles, supplemented with a gel or two for harder sessions.

For hot conditions: Prioritize sodium. Use Precision PH 1500 or double-dose Nuun in your hydration bottle. Fuel separately with gels.

On a budget: Tailwind at $1.15 / €1.05/serve replaces both fuel and hydration products. For pure hydration, Nuun at $0.70 / €0.65 is hard to beat.
