Although nutrition can be a challenge for a lot of runners, it’s key for performance. It is suggested that during endurance exercise (more than 2.5 hours) 80-120 grams of carbohydrate per hour should be consumed. So, in 2018, SiS Beta Fuel was developed to enable us to increase carbohydrate oxidation to more than 60 grams per hour and to achieve that, we combined another form of carbohydrate, which has a different transporter, fructose. Because fructose has a different transporter than glucose, a dual source formulation allows for greater carbohydrate delivery to our muscles during exercise, therefore increasing how much carbohydrate we can use. This unique range of products are all naturally flavoured and can be used in combination to optimise performance during endurance exercise, giving you a scientifically superior fuel source allowing you to unleash your energy.

Though it is important to note, individuals may take time to adapt to consuming this amount of carbohydrate and the optimal amount per hour may also vary slightly depending on the individuals body weight. It is important to practice your nutrition during training to find the optimal amount that works for you. BETA Fuel DrinkFirst launched in 2018, the original Science in Sport Beta Fuel drink was an isotonic product using both maltodextrin and fructose at a ratio of 2:1 to optimise carbohydrate delivery and utilisation during exercise, while minimising gastrointestinal issues. McGregor recommends consuming 30-60g of carbs per hour for the first three hours of running, increasing to 60-90g of carbs per hour if you’re still going after that. This can be in the form of gels, drinks or solids.Priyankaa has an MA in Magazine Journalism from Cardiff University and over five years’ experience in health and fitness journalism.

The 120g carbohydrate intake can be achieved from our drink, gel or jelly chew, or any combination of the three

Something to also consider is the amount of caffeine you want in your energy source. Caffeine has been proven to boost mental and physical performance when undertaking Isotonic exercise, making it a great ingredient option. However, it is not necessary for everyone. So take your own health and needs into consideration. Start of workout I’ll take 1 Caffeinated Gel ( Maurten 100 Caf 100 or SiS Go Energy + Caffeine). This is more for when I’m racing, but if it is a big all out effort, you should follow the same strategy as if it was race day. Got this today…wow if I ate all that before a big ride or race and after it would cost more than big race entry fees. Not to mention I would probably gain weight. Science in Sport Beta Fuel is leading a revolution in endurance fuelling by using both maltodextrin and fructose to optimise carbohydrate delivery and utilisation during exercise whilst minimising gastrointestinal issues. As part of the 2022 Runner’s World Sports Nutrition Awards, we enlisted a 200-strong panel of testers – made up of ordinary runners and experts – to slurp and munch their way through a variety of market-leading energy gels, drinks and chews to find the best on the market.With both gels and chews, it’s important to drink enough water to help your body digest it properly and ensure you stay hydrated.
