GU Energy Roctane Ultra Endurance Energy Drink Mix, 10 Single-Serving Packets, Tropical Fruit (123130)

Good for training

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 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.

I just feel this is a good endurance drink complete with an amino acid blend

good
