Branched chain amino acids reduce mental fatigue, decrease muscle damage, and improve cardiac output during exercise.

Electrolytes maintain water balance and aid in optimum hydration for everyday training and recovery, as well as during sustained, high-intensity efforts.

Caffeine enhances performance by increasing focus and concentration. It can also decrease perceived effort during exercise.

Carbohydrates deliver ready to use energy and delay bonking by sparing glycogen, which the body can quickly turn into fuel when needed.

Product Description

Roctane Ultra Endurance Energy Drink is a carbohydrate intensive energy drink mix formulated especially for ultra-distance and intense racing or training efforts. It contains the critical carbs and electrolyte replenishment that endurance athletes need to compete at high levels. Each serving contains 250 calories of complex and simple carbs that are optimized for rapid absorption and energy accessibility. Key electrolytes, including 320mg of sodium, help maintain hydration. Roctane Ultra Endurance Drink contains beta-alanine which supplements dietary beta-alanine to improve muscle buffering during intense efforts, and branched-chain amino acids, which are shown to serve as an additional fuel source (when taken with carbohydrates), reduce muscle damage, enhance recovery, and delay fatigue. Select flavors contain 35mg of caffeine, which increases focus and concentration, and decreases perceived effort. Roctane Drink is light tasting—not chalky like most calorie-dense drinks—and mixes easily in a bottle with 21 ounces of water. One bottle per hour, supported when necessary by one Roctane Gel, is recommended for races and prolonged exercise. Available in a 1.72-pound/12-serving canister or 3.44-pound/24-serving jar.

Great stuff for Riding!
Trying to get properly fueled for riding has been difficult for me. I finally did some research and came to the conclusion that the best ratio for me is Training Time [Hours] X 60 = Carb Intake [Grams]. GU Roctane makes this easy as two scoops are what is recommended for a bike water bottle and that equals 60g of carbs.I must say that the difference for me is quite noticeable now that I'm properly fueling. I have sustained energy throughout my rides and my time on the bike is far more consistent. The flavor is good and it mixes well. What's not to like?? I also supplement with GU Energy Gels (Tri-Berry) if necessary on longer rides. It's a great combination.I'll be buying more of this and the gels in the future.

Flavor Name: Lemon BerryVerified Purchase
I've been getting back into long distance cycling and wanted to fine tune my salt and calorie intake on long rides. I'm in SoCal so during the summer it's usually 90+ degrees. I usually use Nuun for added sodium and will always drink 22oz of water per hour but I have trouble keeping up with my calories. Regular foods are often hard to handle, carry and digest.

This year I wanted to try something different, so I gave GU Energy Roctane Ultra Endurance Energy Drink Mix a try. I just did 60 mile ride with this and it went pretty well. I had a caffeinated flavor and it was a good amount, but maybe I shouldn't have started with a large cup of coffee before the ride. I'm a little sensitive to caffeine now that I've stopped drinking large energy drinks. The taste was fine. I don't know why people complain of the taste, it's on par with the other supplements. It wasn't too sweet either. The calories went down fine and I had no gas or stomach issues. This was a big plus since I'm able to ingest more calories on long rides. Sometimes I don't feel like eating, but drinking this stuff is easy enough.
I felt great on the ride and the caffeine was felt for sure. It would have been perfect if not for the cup of coffee I started out with. I never felt weird, I just felt really alert and was not able to take a nap after my ride. Next time I'll skip the fourth drink on the ride.

So yeah it's pricey but for long rides it works great.

Flavor Name: GrapeVerified Purchase
Since cytomax was sold to gatoraid and they’re not doing anything with it (thanks Gatorade), I’ve been looking for a suitable replacement. I saw Rocktane and decided to try it.

Taste
Tastes great. Not that sweet. I like sweet in moderation. I typically scrape off buttercream icing off of cakes as it’s too sweet for me. But I’ll eat cream cheese icing with not problem. Grape has a nice subtle taste with just the right amount of flavoring to make it taste light and even refreshing. I cannot stand most energy drinks because they use fake sweeteners or use an ungodly amount of sugar. This has a much lighter taste than cyctomax which I considered very sweet. This seems to have the perfect taste balance for intense or long rides

Stomach
My stomach isn’t sensitive. My stomach didn’t feel weird after using this. No gas, no noises…

Caffeine
Why are companies adding caffeine? If you’re using this stuff your heart rate is already elevated from your workout. It’s not like you’re going to fall asleep during your workout. Adding caffeine just elevates your heart rate even more. I’m pretty sure I’m alert when I’m working out. This seems to be a bad trend. I’m glad grape has no caffeine.

Mix
This stuff mixes completely. I use regular tap water, with two scoops in a large cycling water bottle. Shaken, not stirred. Nothing ever settles to the bottom. It remains that way even after 24 hours (left a bottle out). Nice!

Performance
Rocktane works although not as great as cytomax. Cytomax had something that made it feel like you were exerting less energy and everything was easier. My legs also burned less during high exertion. Rocktane is much more subtle. It doesn’t feel like I’m breathing easier and while it will never be cytomax, it’s better than hammer (tastes horrible-took one sip and dumped it). It’s also better than c4. C4 endurance seems to pump up your legs more, like you’re weight lifting, so it wasn’t for me. Rocktane does control next day soreness (after a hard workout) but doesn’t eliminate it entirely.

All in all, I’m glad I tried this. Ill keep using this until I find something better.

I've used this product for runs of up to 50k and it has done the job well. Keeps the energy levels up, no stomach issues, good electrolyte content. As it is maltodextrin-heavy, it is not as flavorful as the caloric content might suggest. One trick which I have employed (do so at your own discretion) is to spike the mix with some grape pre-workout (NO XPLODE in my case) which adds B vitamins, caffeine, aminos, and also enhances the flavor, with the whole mix coming out to roughly the taste of something along the lines of grape Monster.
