What is this comparison about?
Precision Fuel & Hydration's PF 30 Gel and Maurten Drink Mix 320 sit in the same fueling-rate band but make different chemistry calls. PF 30 uses a 2:1 maltodextrin-to-fructose ratio — the original Jeukendrup-lab dual-transporter mix, well-tested up to roughly 90 g/hr. Maurten 320 uses a 1:0.8 ratio, the O'Brien & Rowlands optimum that shows the clearest advantage above ~90 g/hr. Both are aimed at endurance athletes pushing 60–90+ g/hr of carb intake. The differences stack: PF 30 hands you a 30 g hit in a 60 ml gel at 2:1 with zero sodium; Maurten 320 dissolves 80 g into a 500 ml bottle at 1:0.8 with ~200 mg of sodium.
If you already know which format you prefer (some riders refuse gels; some marathoners refuse to carry a bottle), the choice is made. If you don't, the per-gram economics, the electrolyte tradeoff, and the convenience factor all go in different directions.
What do they have in common?
- Dual-transporter glucose+fructose chemistry (different ratios)
- Maltodextrin + fructose carb sources
- Designed for 60–90+ g/hr fueling targets
- Used in pro cycling and Ironman programs
- Both replicable at home for a fraction of retail
Where do they differ?
| Trait | Precision Fuel & Hydration PF 30 Gel | Maurten Drink Mix 320 |
|---|---|---|
| Format | 60 ml gel, 30 g of carbs per gel — easy to carry, drink water alongside. | Powder dissolved in 500 ml of water — one bottle = one full hour of fuel. |
| Carb per serving | 30 g per gel (target 2 gels/hr for 60 g/hr; 3 for 90 g/hr) | 80 g per sachet (one sachet/hr = 80 g/hr fueling) |
| Sodium per serving | 0 mg per gel (Precision intentionally sodium-free — pair with separate PH electrolyte tabs) | ~200 mg per sachet (Maurten ships sodium with the carbs) |
| Per-gram-of-carb cost (retail) | ~$0.10/g of carbs ($3 gel ÷ 30 g) | ~$0.05/g of carbs ($3.75 sachet ÷ 80 g) |
| Decoupling philosophy | Built for it. Precision sells PH electrolyte tabs separately (250, 500, 1500 mg/L) so you scale sodium independently of fuel. | Coupled by design — sodium comes with the carbs. Fine if your sweat rate matches Maurten's sodium dose; constraining if it doesn't. |
| Carry weight & race logistics | Light, packs into a jersey pocket, no mixing required, can be paced precisely (gel every 20 minutes). | One bottle dominates your carry. If you finish the bottle before you finish the hour, you're out. If you don't finish it, you've over-consumed. |
Which one should I actually buy?
Verdict: Tie — depends on use case
These products solve the same physiological problem — get 60–90 g/hr of dual-transporter carbs into the gut without overloading either pathway — using different delivery vehicles. Per-gram-of-carb, Maurten 320 is roughly half the cost of PF 30 at retail. If you're indifferent to format, Maurten 320 is the cheaper way to get the same carbs.
But format is rarely a wash. Marathon and ultra runners overwhelmingly prefer gels (no sloshing bottle, no dilution problem). Cyclists with bidons happily drink an 80 g/serving mix in a single bottle. Triathletes mix and match by leg.
The decoupling angle is the most interesting differentiator: PF 30 plus a separate Precision electrolyte tab gives you independent control over carbs and sodium, which is a meaningful win in heat. Maurten 320 ships fixed sodium and you can't change it without adding salt yourself.
Pick Precision Fuel & Hydration PF 30 Gelif…
- You're a runner or triathlete who prefers gels for race-day pacing and pocket logistics.
- You sweat heavily and want to scale sodium independently from your carb dose.
- You're already inside the Precision ecosystem (PF&H electrolyte tabs, sodium testing).
Pick Maurten Drink Mix 320if…
- You're a cyclist who already drinks from a bidon and wants one bottle to be your full hour of fuel.
- Your sweat rate is in line with Maurten's ~200 mg sodium dose for the 1-hour bottle.
- You want the lowest per-gram-of-carb cost at retail among premium 1:0.8 products.

Or skip both and DIY
Both products replicate cleanly in a kitchen. The DIY PF 30 teardown shows how to make a 30 g 2:1 gel from bulk maltodextrin, fructose, and a touch of pectin for ~50 cents — versus $3 retail. The DIY Maurten 320 teardown lands the 80 g 1:0.8 powdered drink for ~80 cents — versus $3.75 retail. Different chemistry, different formats, similar ~70–85% savings.
The ingredients involved
- Maltodextrin · The glucose-polymer workhorse in almost every high-carb sports drink — same energy as dextrose, far lower osmolality, nearly tasteless.
- Fructose · The GLUT5-transported sugar that lets you push past the 60 g/hr glucose ceiling — pair with maltodextrin at ~1:0.8 for the modern dual-transporter formula.
- Table Salt (Sodium Chloride) · The cheapest, most-bioavailable sodium source in your kitchen — pennies per gram and chemically identical to what's in any electrolyte tab.
- Sodium Citrate · A smoother-tasting sodium source than table salt — the alkalising buffer commercial drinks use to dose sodium without the bite.
