The standout feature of Voom Nutrition Fusion Fuel is its high carbohydrate content of 90g. As ultra runners, we naturally have high energy demands, and this could be a game-changer during a race.
I was sent the Apple & Blackcurrant flavour which tasted nice but there is also a neutral flavour too which could combat flavour fatigue or be handy to mix with other drink.
The Carbs
Cluster Dextrin: Also known as Highly Branched Cyclic Dextrin, this is a fast-absorbing carbohydrate source that is known for its rapid gastric emptying. This means it moves from the stomach to the small intestine more quickly and it is absorbed more quickly, which reduces the risk of bloating and the discomfort often associated with high-carb intake.
Maltodextrin: used as a thickener or filler in many processed foods, it can rapidly spike blood sugar and is a quick source of energy.
Fruit Fructose: A natural sugar found in fruits. It provides energy and sweetness but is metabolized differently than glucose. In combination with other carb sources, it can offer a more sustained energy release.
The Vitamins
Beyond the carb content, Voom Nutrition Fusion Fuel is fortified with b-vitamins, glutamine, and electrolytes. B-vitamins play a vital role in energy metabolism, while glutamine aids in muscle recovery, and electrolytes help maintain hydration and muscle function. This ensures that not only do you get an immediate energy boost, but you also support your body’s recovery and hydration processes.
Many high-carb drinks can cause stomach upset, especially when consumed during rigorous physical activities. The addition of cluster-dextrin addresses this, making the drink suitable even during high-intensity workouts or races.
The Test
I was sent four Voom Fusion sachets and I used two in training and took two to race the 50 mile ultra Lakes in a Day at the beginning of October. For the start, I filled a 500ml bottle of Fusion Fuel and packed the last one to use at the half way point.
During training, I was caught out initially by the larger quantity of powder. I filled my soft flask as normal with water and then went to tip the contents in. As powder quickly went everywhere, I realised that such a large amount wasn’t going to be absorbed in time as I tipped it in. Top tip! Half fill your flask, empty the contents of the sachet in and then top up with water!
I’m not a fast runner – I’m back of the pack and I don’t need to take on 90g of fuel in an hour. Breakfast before an ultra is always tricky for me – my stomach is tense with nerves and nothing goes down well. Having the Voom Nutrition Fusion Fuel really helped me to feel I was getting some energy in, despite only nibbling on some breakfast. I planned on sipping the Fusion Fuel gradually over the next couple of hours until I felt able to start taking on solid food.
Unfortunately my race didn’t go to plan and I turned my ankle about 8 miles in. It then took me a long time to hobble up the back of Blencathra and meet the safety team. By this time I was well and truly last of course, so they walked with me back to the cars, and then on to the next checkpoint. It took me nearly 6 hours to do 12 miles! However, in this time, all I took onboard was the Fusion fuel. Eating was the last thing on my mind, but when I eventually got to the checkpoint, I wasn’t hungry. At all. This stuff packs a punch.
Going forward, my plan to use the last sachet at the halfway point I think was sound. I think it will really boost your carb intake in the latter stages of a race when eating becomes hard. This is the stuff to have in one flask as your back up, while you have your normal hydration in another flask.
Sustainability
I am gratified to see the packaging is recyclable from home and the fact it is made in Britain is always a huge plus in reducing carbon. Voom Nutrition Fusion Fuel is also vegan and gluten free.
Conclusion
At £3.00 a pack, this is a pricey product at twice the price of it’s hydration counterpart. However, it also packs way more carbs in and lasts much longer over a long distance event so I think it’s worth adding a few of these to your usual order. Voom Nutrition Fusion Fuel is a great option to have in your arsenal for a reliable and sustained energy boost with quality ingredients.
