Salted caramel. Tastes like love.

Proof? I was riding with my kids, and my 7 year old said he was dragging. I had a GU in my bag, so I gave it to him. He KILLED it.

Never heard so much as a whinge for the rest of the ride.

Now he wants to eat them as a snack. are mine....

Good quick energy

Good for a quick boost while running or riding and be sure to wash it down generously with water. Wife likes Strawberry w/ no caffeine. I like Salted Caramel and Plain. Orange and Lemon lime are ok but only in winter.

Gu-d Stuff

  • Familiarity: I've used it once or twice and have initial impressions

I have just recently been using different energy gels for my hiking, biking and fishing excursions and tried out Gu gel over a long weekend of backpacking, and was very happy with the results. After climbing Mt. Hatch I downed one of these because I was starting to feel the burn and could tell that my energy stores were running low, the caffeine and simple sugars provided me with the boost I needed to take the treacherous descent down without crashing. I tried the Mandarin Orange flavor and the taste was okay, but I just sucked it down and chased it with a swig from my Camelbak. One note, Gu like many other energy gels will leak and get your pack messy once the gel heats up after you have eaten most of it, so really squeezing out every last drop is definitely beneficial to you and your gear.

keeps you stable

I always assumed that the energy dips while hiking (both mental and physical) were always going to be a standard for me...that is until I used GU and used it as directed (every 45 min). I've stopped counting down miles, minutes, etc and keep focused and calm and moving whether it's a long backpacking trip or even just a 1 hour bootpack to skiing. The flavors are great, and a great treat is spreading the salted caramel, vanilla bean, or peanut butter on a chocolate bar...delicious.

Best Flavor: Salted Caramel

  • Familiarity: I've put it through the wringer

Never thought I would applaud an energy gel for its flavor, but the Salted Caramel is good. Great. So great that I'm worried I'll need to grab another box or two in case it truly does end up as a limited time production. I like that it's a lower caffeine option (20mg). Previous favorites have included Mint Chocolate, Peppermint Stick, Espresso Love, and Peanut Butter. But Salted Caramel definitely takes the cake in my book! I take one of these mid-way through long runs greater than 10 miles.

These complete me.

  • Familiarity: I've put it through the wringer

These complete me. When I am on the bike/running/trail I pull one of these out to give me that blast of nutrition to keep me killing it. These are super easy on the gut and allow me to feel confident that they will give me what II need to get the job done.

A good option

    Gu seems to be one of the more difficult brands to find in stores in my area, but I do like it, especially the peanut butter. I find Gu to be one of the thickest gels out there and the flavors are never overly strong, but PB is a great option that I don't think anyone else makes. I like to have a variety of gels and Gu doesn't disappoint.
