GU Original Energy Gels, Jet Blackberry 24 Pack - 100 Calorie Energy Gel with Carbohydrates, Caffeine, BCAAs and Electrolytes - Pre-Workout Fuel for Running, Cycling, Triathlon and Endurance Sports

I've tried a couple of the flavours of these gels and the blackcurrant one is my favourite so far - it doesn't taste as chemical-y as other ones like vanilla so is far more pleasant. They give a good boost in energy too and stave off a bit of hunger for a while. I find them really useful in-between tennis sets or having a small amount in-between changeovers. Good product!

Only gel I have used that doesn't cause me stonache issues during endurance runs

I switched to these gels from the Sports in science gels. Size wise a key factor on a long run or cycle you can easily fit a few into a pouch. Taste & texture is good (must be washed down with some water) however the added caffeine gives you that little extra boost which & the other ingredients is already helping your recovery. Glad I went for the BlackBerry Gel probably the best flavour. Also these are Gluten free & Vegan friendly!

I only use these on long runs (15km +) and they seem to help. I don't know whether it is just psychological but I look forward to the sweet kick every 45 minutes or so and it helps keep me going. nice and compact to store in a belt/pocket as well so don't get in the way. flavour is personal preference of course but these are sweet and taste ok once you get used to the texture.

I used these for the first time doing a 110km bike ride in Cape Town. I'm by I means an endurance athlete and this was the longest cycle is ever attempted by about 3x. I was recommended these Gu sachets by a keen cyclist who raved about them and have to say that they lived up to the hike. I used three during the race and felt a massive improvement when taking them, especially the first one.

My go to gel for long runs

I'm getting use to the non water gels. This one is thick but tastes fine.

The best before date is in June 2025, therefore I have returned it

Helped me a lot to gain energy especially with my long runs. Tolerable taste and easy to digest haven’t have upset stomach so far. You’ll get your value of money and your quality run goals.

I really like the product and it is very effective on my training times and road racing

have bought several cases of these for running and cycling. love the flavor and are each on my stomach and don't leave that sticky or chalky feeling in your mouth. would highly recommend

I would not compete without these. They have been great for an added kick during triathlons or just before an intense gym work out. Never any jitters- even with the caffeine. They fit easily into a tight pocket and taking two or three with you for an extended competition is simple. The texture takes a little getting used to but after two or three, you get used to it. I like the jet blackberry with caffeine best. I recommend one about 15 minutes before your workout starts. If you are competing for a length of time, maybe a second an hour later.

I have just started training for a 50 mile Ultra. During my training after running for an hour or more it became a struggle to have the energy to continue. I was previously using Starburst and other snacks to fuel my runs however many times they would effect my stomach in a negative way so I decided to give these gels a shot after reading the reviews. I chose the Jet Blackberry because they have caffeine in them. The texture and consistency is like honey and they are probably as sticky as honey. They are very easy to open and I was able to fold the wrappers with little effort and store in my pack. They didn't make a huge mess in my pack when doing this. They are very easy to consume while running and after about 10 minutes I did feel a nice burst of energy. I had a lot less cramping and upset stomach on the day I tried these gels. The flavor was good. It wasn't the best snack ever however it wasn't difficult to get down and tasted very similar to a fruit roll up but not quite as sweet. I will continue to use these gels throughout my training. I feel like they are a necessity for long runs. Next I would like to try the Roctane version.
