These energy gels taste great and give me a boost when I'm doing long cycling sessions or out doing hiking, but you don't have to be an athlete to benefit from them, even just moderate cardio can get you very exhausted. It's been difficult to find a good energy option that's caffeine free, but these were fantastic! When it feels like I'm getting tired and I'm thinking about needing to cut my adventure short, I open up one of these and within 10 minutes I feel like I'm back! My muscles come back online and I feel like I can keep going as long as I want. Definitely made a fan out of me!

I have been using GU packs for all of my 40 marathons and the training since 2008. I highly recommend. That said, I get stomach issues from any of the fruity flavors, I can only do chocolate, vanilla and caramel. So fo you, you have to see if one type of flavor works best, Roctain or Regular. But they really work for me personally and I have run 10 Bostons, qualified IDK 15 times. 1 before the run or race and then 1 every 5 miles, but I do an EXTRA one at mile 17. No bonking. Whatsoever.

Like many reviewers, I have Type 1 diabetes, insulin controlled for over 65 years. I am also a backpacker, and have learned that the exertion of toting a load of gear tends to result in low glucose, no matter how much I try to adjust my insulin dosage. When that happens, I need glucose easy and quick. Gu Energy Gel is my go to fix. And my favorite is Vanilla Bean. Please keep making it...all the new-fangled energy dots and shots just don't do the job.

I am a new cyclist but I adore cycling. I've been a lifelong runner but cycling is a new found joy! Last year I cycled 42 miles as my longest ride. I mix my training with running and hiking mostly in northern Michigan which has a lot of hills. Where are live there are some of the highest hills in the state. With Gu energy gels I can go the extra mile. As a novice cyclist, I've experienced the bonks as it is similar to hitting the wall. With proper planning, nutrition, water, and Gu energy gels I don't hit walls or bonk. I've been able to go on shorter rides from 20-30 miles and feel great! My favorite is Chocolate Outrage! Seriously tasty As someone who is lactose intolerant as well as having a wheat allergy I appreciate these being vegan and gluten free!
Sometimes you need energy, but don't want food. I have a friend who is trying to get into shape and gets exhausted on hikes, but can't handle food and these have been exactly what they need.Here is my opinion on a few flavors:Birthday Cake- It's birthday cake. It delicious and by the second or third taste you realize it's way too sweet... but you keep eating it lol. It's birthday cake.Cola- Its flat Cola. Ever had some leftover coke in a bottle you left capped and hoped it still had gas when you went for a drink only to be disappointed that it was flat and just tossed it out? This is that.Caramel Macchiato- ever had the iced coffee from a place like 7-eleven? Its kind of chemically and you understand what they were going for but its not that. This is that. ...

Maybe you like it. I do not.Chocolate Outrage- Chocolate, not too sweet, but just a tad chemically. Not as bad as Caramel Macchiato, but not my favorite.Espresso Love- Tastes like fudgy pudding. Its delicious and I can't get enough.Vanilla Bean- Sweet, not as sweet as birthday cake, no chemical taste. Very good option.
These energy gels have proven themselves to be real life-savers... literally. I'm diabetic and don't always realize that my energy is flagging. Fortunately, I keep these on hand - in my pocket and in my backpack - for when I feel that drop in blood sugar. They work faster than eating a piece of candy and the caffeine kick in some of the flavors helps to curb any headache I may have gotten from allowing my sugar to fall. I also use them when hiking in general, to keep up my stamina between meals. They're easy, fact-acting and highly portable, making them perfect for traveling.
I am a very active type one diabetic and have always used glucose tabs or gels for lows (among other things). I have found that they treat the low but I feel worse after because my blood sugars spike then I crash back down.I started using Gu when I was going through the fire academy this winter, what a game changer! I would take one before a training evolution and not worry about my numbers dropping. In fact, my numbers stay almost perfectly straight, I have learned not to enter the carbs into my pump and it balances out.Now I keep 6-8 Gu in my turnout gear and just got back from 2 calls, my numbers were 135 when I got back to the station and I felt refreshed and ready to go back out! The electrolytes are an added bonus.At first I almost gagged when I tried it, ... MoreI am a very active type one diabetic and have always used glucose tabs or gels for lows (among other things).

Raspberry lemonade isAwesome and blackberry is too, but 40mg of caffeine is a bit too much. Salted watermelon is my go to.
Ok, so overall I'd say most flavors are quite decent and don't taste awful. But there is one that brings the whole thing down, and that's the Raspberry Lemonade. I figured I'd love it since I like the fruity gels, and I love lemonade. So imagine my surprise when I take one out for some quick fuel 13 miles into an 18 mile hike and about to start on a 3800' elevation gain, and it tastes like neither raspberry or lemonade. The best way to describe the taste would be like how Clorox wipes with Febreze smells. That's what this one tastes like. Or some kind of artificially fruit scented floor cleaner. It is BAD. Like, want to immediately barf bad, gotta drink my entire bladder of water to get this out of my mouth bad. I know taste is subjective, and I'm sure someone out ...

Tried the TRI-BERRY flavor, after other flavors that I like, this was a tasty treat. I like sweets.I have experimented with the energy gels' using', 'not using', 'after30 minutes' changing timing, on a controlled 33 mile route I pedal for workouts, consistent temperature, water intake and time of day; I have found that when I delay or skip the gels, I can tell the difference in energy/firepower. Ingesting a gel later is better than not, as I sense a pick up 5-6 miles down the route. Cold water, small recovery segments and GU gels have made a big difference in performance.
For the weight/calorie/size ratio, this is one of the more portable foods. I usually carry PBJ/applesauce/fig bars or something I can get from the grocery store but they can take up more space. Replacing some of the calories from the "real" food will help free up some space.I don't like sweets and I think this affects my judgement of the flavors. I just try to gulp it all down in one go and chase with water.
