Sweet, smooth, rich and creamy, Vanilla Bean is a classic flavor that just gets the job done… mile after mile after mile. Not every session is going to need that high volume of fuelling, but you might have one key session during the week where you use those race fuelling patterns. Each 45g gel contains 30g of carbohydrates in a 2:1 maltodextrin-to-fructose ratio, which allows you to absorb more carbs per hour, and there are also five electrolytes thrown into the mix to help replace what you lose in sweat.Scan nutrition labels to understand how many carbs your product of choice offers, then take that into consideration when determining how many you’ll need to stash in your shorts or belt on the run. Elite marathoners do use gels, but because they have dedicated drink stations where they can take on their preferred pre-mixed carbohydrate drinks without having to carry them, the bulk of their fuelling during a race is often done through drinks. Consider the energy demands of your sport to help you determine if energy gels will be good for you.
