Energy gel : concentrated carbohydrate fuel

Intensity

Concentrated fueling format (~22-25 g of carbs per packet) designed for rapid ingestion during effort, without chewing.

An energy gel is a semi-liquid preparation rich in fast-absorbing carbohydrates (maltodextrin, fructose, glucose) packaged in a 30-40 g sachet. The goal is to deliver 22-25 g of carbohydrates without chewing or drinking large amounts. In Ironman, the target is 60-90 g of carbohydrates per hour (up to 120 g/h for athletes trained for high absorption). Gels alone rarely suffice: they need to be alternated with solid food and hydration. Testing in training is mandatory : some gels cause digestive issues.

In TriPaced:

In TriPaced, long sessions (>1h30) include a nutrition note indicating when to introduce gels. The fueling strategy is personalized based on the estimated duration of each race segment.
