GU EnergyRoctane Ultra Endurance Energy Drink Mix, 10 Single-Serving Packets, Summit Tea

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

Nice flavor, I used it for the bike ride during a very hot 70.3 Ironman and worked great.It is a bit pricy but I’ll buy it again

I would not say to buy it for the taste, but GU Roctane Energy Drink Mix seems to be an effective product. It's difficult to judge how well a product like this works -- every ride is different -- but it's easy to drink, is not overly sweet, and keeps hunger pangs away during the ride. My test was a 32 mile ride after only being able to ride a couple times in the past two weeks. Plus it was following a very late night due to a band gig. Expectations were not high, but my legs felt fresh during the ride, and my energy level remained very consistent for the duration. It packs a lot of carbs but is only 16g of sugar, which is maybe why maintains energy level without a subsequent sugar crash. GU says drink one bottle every 1 to 1.5 hours, which seems a little much, but maybe not on a hot day.

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.
