GUEnergy Roctane Ultra Endurance Energy Drink Mix, Vegan, Gluten-Free, Kosher, 35mg of Caffeine, and Dairy-Free n-the-Go Energy for Any Workout, 10 Single-Serving Packets, Tropical Fruit

Very much enjoy the taste, my husband says it gives off kids cold medicine vibes, but I think the grape is more like Gatorade. In terms of performance, think the product works great for efforts over 1 hour, I supplement with other products to get to 100g of carbs/hour but this hasn't give me gut issues!

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.

Good for training

As someone who pushes through long runs and intense training, the GU Energy Roctane Ultra Endurance drink mix has become a staple. Each Summit Tea packet delivers a solid 250 calories of quickly absorbable carbs, a hefty 320 mg of sodium to keep hydration in check, and a powerful blend of amino acids (BCAAs plus beta-alanine) to help fend off muscle fatigue and damage. The light, refreshing taste mixes cleanly in 21 oz of water — no chalky or sugary aftertaste. It keeps me focused and energized, mile after mile. Whether you're racing or grinding through training, this is a rugged and practical go‑to energy boost that keeps you rolling strong.

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 mix isn't super sweet like gells are so it is a great alternative. Got me through many 3+ hour rides and used it for 70.3 nutrition after I got sick of the GUs.

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