This is a great product for sustained energy. Be certain to purchase the GU with caffeine as was recommended by a friend of mine who is a personal trainer. Follow the directions to take one approx. every 45 minutes and you can push your effort. I never tired during a 50 mile bike ride in the Adirondacks and I attribute that to this product.
I used to prefer this gel over the more liquidy PowerBar gels, but not any longer.
All in all, this is a very good product, but I find it just a little tough to swallow, it's so gooey, it's almost like slugging down raw honey or something?
Pros It works to keep you moving and definitely helps you get up that next big hill or to keep up in your paceline after a long day in the saddle.
Cons A little on the gooey side.
The numbers don't lie. Speed
Increased .7 mph while hawing this as directed.
I use it every ride. I thought coconut water was best. Maybe it is. But I'm so impressed with this stuff. I bought 2 big boxes.
I was doubtful at first but the numbers don't lie. My average speed increased .6 mph while using this stuff as directed. Taste great. The caffeine boost is nice. I always swore coconut water is best. But this with the coconut water seems to work great. I bought 2 big boxes of this stuff. I use it every ride.
This is my second favorite flavor and a consistent go-to for me. Try the salted caramel if you want an even sweeter (literally) gel.
Good mix of flavor without being too sweet.
I don't notice any real kick from the caffeine, but I do notice the energy kick.
I use GU to start refueling 30 miles into my ride. This workers well with my other fuel that I am eating so I don't end up bonking before I get half way through my ride. I only need to take a few of these for a century ride so I don't need to fill my pockets.
I've used both the GU and GU Roctane for 5 years primarily for marathons and long training runs and these have always been reliable. The flavors are based on personal preference and it takes time getting accustomed to the taste. Definitely practice fueling at least 3 to 4 times during long runs, as I would suggest taking a gel everything 5-6 miles to start and if you need more then you can increase consumption. I have only relied on GUs and salt pills during races which have been the only fuel required to get me to the finish line. The sodium citrate (versus sodium chloride) is less acidic and easier on the stomach, but consuming too many during a long race may lead to GI distress due to the heavy consumption of the maltodrexin in these. Train appropriately, figure out your ratios and you won't have any problems. Highly recommend this product.
The boost these provide is substantial. If I'm running a little low on energy they always pick me up. Taste is good. I usually get caffeinated variety's. If I'm riding by myself it is easy to eat solid foods, but if racing it is harder to do. These are very easy to open and eat when on the rivet.
