GUEnergy Roctane Ultra Endurance Energy Drink Mix, Vegan, Gluten-Free, Kosher, Caffeine- Free, and Dairy-Free n-the-Go Energy for Any Workout, Assorted Flavors, 10 Single Serve Travel Size Packets

I have been using GU products for a while and they taste good and work good. I use them for biking and they definitely give me a boost. I always get some with caffeine. Never had any stomach problems with them either.

I want to buy the big jug .I don't need individual packets like this unless I am traveling. I used this for my first ever ultra race and it was amazing. I did have GI issues that kept me from eating well. This helped me keep carbs and electrolytes going in. Amazing taste!

I took this on my half marathon. The taste is good. It is thick like toothpaste consistency. I do not like the delivery system. It was hard to tear open and messy when taking it. So not easy to use especially while running. I think it gave me the energy I needed to keep going.

I just spent 7 days riding 68 miles per day on average with a 100-mile century thrown in at RAGBRAI in Iowa and this stuff made a huge difference.On the days that I did nothing but Gu Energy Roctane Drink Mix (w/ caffeine in the morning and w/o in the afternoon), Gu gels, Gu stroopwafels, with plenty of water, and Gu Roctane Protein Recovery and Gu BCAA after. I felt fantastic. I crushed my PR for a century with a 21.5 mph average over 103 miles. On other days, I ate other food and felt awful at the end of the day.(I will add that I used PR Lotion. I feel that helped my performance, too.)There's no question that Gu's stuff helped me to hit my maximum performance. It provides a perfect blend of nutrients and electrolytes. And considering that it's a meal replacement, it's a no-brainer.I will be using this for all long rides in the future.If you look at this as meal replacement it's a check of a good deal.

I’ve always been unable to tell the difference between drink mixes for bike rides. This one makes a difference and the taste/sweetness is just right. I’ve switched to the plastic jug since the packets are so expensive but good to carry on long rides.

Three stars may be an unfair rating. Basically, I drank a box of these before and during long runs (20 to 35km) and enjoyed drinking them, but no more so than any other drink. I didn't come away with any real sense of being especially well hydrated or energized, or not. There were so many other variables that determined whether I felt well equipped during those runs - temperature, wind, what I was eating, whether I was more or less tired before beginning any given run, etc. In short, based on my own runs I find it impossible to fairly evaluate the product other than for taste (fine, but not a drink I would request in a restaurant) and digestability (no problem), ease of mixing with water (easy - but some bits appeared to flat around afterward and may have got caught up in the nozzles of my water bottles - although this was not a problem when I drank).

This product roctane great for the runner,hiker,cycling!!!
