I purchased 3 different products to help me with fuel during a half marathon. I'm reviewing all 3 and will copy this review to the other two. My first purchase was KrampKrusher energy gummies. The second product was GU energy gel. The third product was Wasatch Nectar Honey. They were all good products but for different reasons. I liked the KrampKrushers but they were hard to get out of the bag while running so I used those about 60 minutes prior to a training run. They were super salty and had a tart lemon flavor. The Wasatch Nectar was easy to dispense and tasted fantastic but made my saliva super thick. Unless you are near a water station or carrying your own fluids, I don't recommend this product during a run. I ended up using this product at the start of the run or race with a little bit of water. The GU was my favorite fuel during the race. Birthday cake flavor was a little more intense than I would have liked but, like the Honey, it was very easy to dispense and consume while also running and breathing heavily. It also did not thicken my saliva. I think all three products served their purpose but timing of use became an important factor for me. I'm glad I tried them ahead of time and found out the drawbacks of each before race day. If you do the same, you'll know what to expect and should have pretty good luck with the product.

Overall, these are fine and suited for their purpose. Personally, I think they are very sweet and very viscous to the point of almost being hard to get down while running. It’s almost the equivalent of having a spoonful of rich frosting. Overall, they do what they should but if you have issues with textures, you may not like these.

I use GU Energy Gel for long bike rides and workouts, and it does exactly what it’s supposed to do—gives a quick, steady boost without making me feel jittery or nauseated. The texture goes down easily, and it’s convenient to carry and use mid-activity. I like that it provides carbs and electrolytes without feeling heavy. It really helps prevent that sudden energy crash. A solid choice for endurance exercise or anytime you need fast fuel. I ordered the Birthday Cake flavor and it is DELICIOUS! It gives me that little extra push I need on the return home from a bike ride!
