Customers praised this carb drink for providing sustained energy during endurance activities without stomach issues. Many highlighted the "natural taste" and natural ingredients as key strengths. Some found the pineapple flavor too strong and noted the large serving size makes packages run out quickly. Overall, shoppers reported improved performance.

Fuel for London to Cannes ride

Been using 33fuel for a while. Avoids the extreme sugars of other brands and have always had a calm stomach on long endurance rides unlike when using other stuff. Give it a go.

So far so good

Have been using on my longer swims , trying to find something that doesn’t upset my stomach like other energy drinks. I don’t love the flavour but am willing to put up with that as so far not stomach cramps, and good energy !

Best tasting Carb Drink

I love these drinks, it’s the first drink I can take on rides, swims and runs without feeling I need to wash it down with water. And I actually really like the taste, what a bonus!

Although I don’t run long distances I do run early in the morning when a normal breakfast just doesn’t settle for 5am starts. I purchased 33Fuel Carb Drink after reading several reviews of the subtle refreshing taste. They were totally correct. The taste and results speak for themselves. Returning from 8 day stage race, racing different times of the day 33Fuel kept me strong, fuelled and with no tummy upset. It’s become part of my training & race region now I won’t be going anywhere else.

I am all for this product.

I have ditched any kind of athletes nutrition based on Maltodextrin a while ago, and the 33Fuel Carb Drink is by far the best hydration out there for biking, running and swimming. I love that it’s not sweet or artificial tasting, the natural ingredients make me feel “safe” and not like I am feeding my body some chemically processed junk. I am all for this product!

Worked a treat.

Used for the first time properly in a mountainous 52-mile race. No stomach problems. Easy to drink and mix and tasted fine throughout a long day. Mixed slightly stronger than suggested on packet to increase carbs per hour. Very impressed.

Essential fuel for my Audax cycle rides

I'm probably not the target market as all the athletes shown are much younger. At age 75, I am amassing my Audax Randonneur Round the Year awards, riding 200 km in a day, every month of the year. I start with two bottles of Better Fuel Carb drink, a bottle of plain water and (in my tailfin seatpack) a 500 ml bidon with Carb drink powder to which to add water on stop. Also, of course, a couple of 33fuel energy bars. If it's a ride where I don't expect to find a good lunch stop, I substitute one bottle for the Elite meal replacement mixed with banana. This strategy has kept me going on my Audax 200 km DIY and calendar rides: I've never had to abandon one or come close to it.
I was introduced to 33fuel at a Cyclefit seminar with Warren and Erica and I've never looked back.

33 Fuel carb drink 3 peaks cyclocross race

Used thé carb drink for the first time last weekend at the 3 peaks cyclocross race.
Primarily I chose it in an attempt to combat chronic cramp that is the curse of most competitors at this event.
I drank 500mls before the start and took on 1500mls during the race ( 3 1/2 hour race ).
It worked beautifully, cramp wasn’t a problem and my energy levels were maintained right through to the end of the race. I can’t recommend this highly enough , after the race I still felt energised and cognitively sharp.

Another great product

My go to energy drink. Having started taking up ultra running and being vegan, I am conscious of what foods I consume, and discovering 33 Fuel has made such a big difference to my performance. Not only do their products taste great, they actually work.

Fantastic product

Another great product in the range, super soft on your stomach and full of energy. Tried on a 3hr bike ride and felt really fresh at the end.

Brilliant

I was a bit dubious about water soluble energy products. I took the plunge and used this for a 628 km Audax ride this weekend.
I did one bottle per control stop ( about 65 km each).
This product was very drinkable, and saved me from bonkng. I used it in conjunction with Amore bars, GORP (Good old raisins and peanuts) and the odd meal snack at the stops. No cramps, etc,
I completed the event with power still left. I will be buying this again.

Marcus Bosano
My go to liquid fuel

The more products that 33Fuel ad to their roster the more impressed i am. I have switched to this having been a tailwind fan for a number of years.
It's a great product as it just works and is invisible. By that i mean it doesn't impact my stomach and keeps me fuelled. As a type 1 diabetic this is important and what i really liked about this product was that i didn't get blood sugar spikes. An even release is very important.
As always with 33Fuel products it works, it's quality, it's vegan and what's not to like.

amazing fruit flavor

The drink is light and fruity.
The taste of pineapple is a bit too strong for the amount of calories in it (I'm using a much more diluted version).

But overall experience during the runs is much better than with other drinks that I've used in the past.

Good race fuel

Used this in a race for the first time last week. It was an hour long cross race in the heat, 2nd vet and 3rd senior. I was very surprised to go that well. I think it works!!!

At last

So happy to have this natural energy drink, perfect for long rides and racing when I need to keep in position on the bike. No sickness, a natural high!
