Sports Nutrition for Triathletes

Triathlon demands control across three disciplines. Your fueling determines how stable your energy is from start to finish.

  • Energy: carbohydrates support sustained effort and a smoother transition into the run.
  • Hydration: fluids and electrolytes support endurance and muscle function.
  • Recovery: refuel well to restore energy and stay consistent in training.

Frequently Asked Questions

Start fueling early and stay consistent throughout the race. Most athletes aim for 60 to 90 grams of carbohydrates per hour. The bike is the key moment to take in enough energy, as it is easier to eat and drink. A steady intake helps maintain your pace and prepares your body for the run.

For a detailed breakdown of carbohydrate intake and how to build your strategy, download the Amacx Triathlon Fueling Guide available above on this page.

Take an energy gel every 20 to 30 minutes, depending on your carbohydrate target. On the bike you can combine gels with bars or chews, alongside your hydration strategy. During the run, gels are often the most practical option due to their ease of use. Consistent timing helps maintain energy levels and keep your effort controlled.

Nutrition between disciplines starts before you reach transition. Use the bike to fuel consistently so you begin the run with stable energy levels. Aim to finish your bike segment well fueled and hydrated, rather than trying to catch up later.

Keep transitions focused and efficient, with your nutrition plan prepared in advance. This includes knowing what you take and when, so you can stay in rhythm and maintain control throughout the race.
