Custom Drink Mix (1kg)

No two athletes are the same. So why are you expected to fuel the same?

Build your mix in the custom builder

Who it's for

The heavy sweater who needs 800mg of sodium, not 200. The ultrarunner who wants 90g of carbs with barely any sweetness. The triathlete who wants caffeine in the bike bottle but not the run bottle. Anyone who has ever thought "this would be perfect if only it had more of X."

What you choose

Carbohydrate amount and ratio. Sodium and electrolyte levels. Flavor and flavor strength. Caffeine or none. Then you name it, and the bag shows up with your name on the label.

How it's made

Every custom mix is blended in small batches in-house, which is how we keep the price at $35 a kilo. Orders placed after 10:00 AM CST ship the following business day.

Why Blank's

Sweat rate varies up to four times between athletes. Carb tolerance varies even more. The big brands sell one recipe to everyone and spend the savings on marketing. We flipped that: build the recipe for you, skip the marketing budget, charge half the price.

FAQ

How do I know how much sodium I need?
Start with how salty your kit gets and how much you cramp. For a real number, the Nix Hydration Biosensor measures your sweat sodium directly. Or ask Ike, our nutrition assistant, and it'll build a starting point from your answers.

What carb ratio should I pick?
2:1 for everyday sessions and sensitive stomachs. 1:0.8 when you're pushing past 60g an hour and need the extra absorption.

Can I reorder the same mix?
Yes. Saved mixes live in your athlete portal so you can reorder in two clicks.

Can I add caffeine?
Yes.

How long does a custom order take?
Mixed to order and shipped the next business day for orders before 10:00 AM CST.

Flavors were great as always!

I’m a competitive Ironman triathlete and marathoner, and can honestly say the customizability and price of Blank’s is unmatched. The flavors are amazing, and being able to get in all the carbs I need for the day is effortless. Been using the Custom Mix for a couple of years now, and will continue for years to come!

I've tried just about every brand of sport's nutrition on the market, and nothing comes close to Blank's. GI issues plagued many of my past races due to a lack of ability to customize the sodium content of my nutrition. With Blank's custom mixes, and dialing in my sodium needs, I have been able to have some of my best 70.3 and 140.6 races to date!

Great product. The flexibility and adjustments you can make offer a wide variety that’ll cater to anyone’s needs

This is my go-to nutrition for ultra running races and training. The flavors are the best I’ve ever tasted and the variety ensures I never get palate fatigue. Plus- the prices are highly reasonable and always quick shipping.

I always enjoy the mixes I get from Blank’s! The fully customizable mixes that cost less than a generic product from other brands is an incredible deal. I can’t wait to explore the other products they have to offer.

One of the best ever I had from cost and quality and love to support such a brand

The product is awesome. Being able to control and mix your exact macros is beyond convenient. I’ve replaced 5-6 different products with one bag of Blanks. The flavors have all been great. I really liked the variety pack they offer. Root Beer was surprisingly good! Anyway, the one and only thing I don’t like about the product is how it tends to clump if you let it sit in water for too long, even 20-30 seconds is too long. If they could figure that out it, Blanks would rise even higher than they already are, which is already above everyone else.

The anti-bonk formula!!!!

Very good, only problem is that sometimes there are some clumps that don't mix properly.

Love the idea and the ability to create your own mix! I need to figure out what flavor I prefer because the one I chose was a little too sweet for me!

This has been a serious level-up for fencing. It really made me realize how important proper fuel is for what you're doing. I am so much more in tune with what I am putting into my body, and this is absolutely going to change the game for tournament days!

Amazing product! Best tasting drink mix on the market and to be able to customize it is amazing!

Been using blanks for over a year and has been working great for training and racing. Cost effective carbs for high carb training...100k-100mile.

Been using this product exclusive when training and racing. Having an ostomy bag is hard to find products that my gut can handle, and can handle over long 4-8hr endurance races, Blanks Nutrition has filled that need. Highly recommend.

Took the blue raspberry Bicarb before a long run and a track workout so far and it is just as effective as Maurten but tastes 10 times better! Highly recommend! And the watermelon drink mix is fire too

Tried the new missile pop flavor, and well... that topped my favorite flavor they had. I know what my next order will have every time!

Simple hydration/nutrition in a bottle

By far the best race and training nutrition I’ve tried! It’s cheap, easy on the stomach, and being able to add more sodium to my drink mix has been such a game changer for Ironman/Half-Ironman racing!

I usually purchase the tangerine flavor but went for some pineapple this round. The new flavor seems to carry a chalky like texture in the mixture as compared to the tangerine. I also switched raised my carbs per L which changed the number of scoops per liter but wasn't aware I also need to change the sodium content so that would be stable. Still learning as I move to higher carb fueling. Otherwise really enjoying the custom mix product.

M
Marian Nowak

It is far too sweet. I can't use the recommended full scoop because the sweetness level is off the charts. If I could do it again I would have gotten it without aspartame added.

E

This is my absolute go to nutrition for ultramarathon training and races. I always customize it based on my carb and sodium needs (less sodium for cool weather, increased sodium for hot conditions). Plus nothin beats the taste!

Blanks Sports Nutrition nailed it with their custom drink mix. The flavor options are fantastic! Spirit of the Seagull is my personal favorite and I keep coming back to it. Being able to dial in a mix that actually tastes good makes staying hydrated during training so much easier. Highly recommend.
