Peanut Butter Banana Recovery Smoothie for Triathletes

Why This Recipe Works for Athletes

The peanut butter banana smoothie is one of the most effective quick recovery drinks a triathlete can make. The banana provides fast-release glucose and fructose to replenish glycogen stores immediately after training, while peanut butter adds protein and healthy fats that slow subsequent absorption and aid muscle repair. Made in under five minutes, it is an ideal post-swim or post-run drink when you need to eat quickly before your next meal.

Ingredients

  • 1 large ripe banana (ideally frozen for a creamier texture)
  • 2 tbsp natural peanut butter (no added sugar or palm oil)
  • 250ml semi-skimmed milk or unsweetened oat milk
  • 1 scoop (30g) vanilla or unflavoured whey protein (optional)
  • 1 tsp honey
  • Pinch of sea salt
  • 3-4 ice cubes (if using fresh banana)

Instructions

  1. Add all ingredients to a blender: banana, peanut butter, milk, protein powder (if using), honey, and salt.
  2. Add ice cubes if using a fresh banana rather than frozen.
  3. Blend on high for 30-40 seconds until completely smooth. The texture should be thick and creamy.
  4. Taste and adjust: a little more honey if you want it sweeter, a splash more milk if you want it thinner.
  5. Drink immediately, ideally within 30 minutes of finishing your session for maximum glycogen replenishment.

Nutrition Notes

Per serving (without protein powder): approximately 380 calories, 14g protein, 45g carbohydrates, 17g fat. With whey protein added: approximately 510 calories, 42g protein, 48g carbohydrates. For a dairy-free version, use oat milk and a plant-based protein powder — pea protein blends work particularly well with the peanut butter flavour. For a lower-calorie version, use powdered peanut butter (PB2) to roughly halve the fat content while keeping the flavour.
