I'll preface by saying I'm not into sweets (french fries please!) and can't stand gooey textures... I can barely stomach Jell-O. So I was extremely hesitant to try this, but I got a sample of the Roctane at an expo before my last race and I'll tell you it is amazing stuff.
I could barely stomach the regular GU, even with the more tart flavor, but the Roctane is fine. It has more of a pasty texture than the other stuff, almost like ground fruit roll ups or something. I probably will not try the vanilla one but it's more of my personal taste. The pomegranate/blueberry has a good taste, even when you're super exhausted mid-run.
The best part is the great boost it gives you. I've tried a lot of other products - "normal" GU included - but the Roctane is a much more powerful energy boost.
It's expensive so I stick to cheaper alternatives for sub 90 minute runs, but if I'm out on race day, or planning to run beyond 2 hours it's definitely along with me.

I had always been a fan of tri-berry regular gu, and of clif shots and clif blocks. I never saw the need to spend 2x as much on this roctane version.
On some of my longer runs that take over 3-4 hours I would get hungry and need something beyond just gel, I needed to chew on something so I became a fan of the chews.
Well, during one 50 mile trail race, I started to bonk right around mile 35. I had been eating chews up to that point, and clif shots, but they both seemed too sweet and my stomach just did not agree with them.
My dad, who was crewing for me, had bought some of the roctane's, and he put one in my pack. I got it out, ate it, and noticed that it seemed to taste good to me even though nothing else seemed palatable at that point. Also, within no more than 5 minutes, I felt markedly better. My stomach settled, my energy returned, and I felt good. I was surprised that it made that much of a difference.
I have since learned that it was perhaps the inclusion of the extra sodium along with the BCAA's that most likely did it.
Any run longer than 3 hours and it is my gel of choice. I would take it on my two hour runs, but it is just too expensive and the benefits dont seem to be as noticeable until I really crank up the time.

Wow! I have tried every energy product on the market and this is the one for me every time. I especially like blueberry and that is a flavor that is rare on the energy market. I do not know all the scientific aspects, but it works well for me on long triathlons, trainings and when doing some tough backpacks.
