Homemade Rice Balls for Long Rides

Why This Recipe Works for Athletes

Rice balls (or musubi) are a staple on-bike nutrition for long-course triathletes and ultra-cyclists. Each ball delivers a concentrated dose of easily digestible carbohydrates with a savoury flavour that makes them more palatable than gels after several hours of riding. They’re easy to eat while cycling, hold together well in a bento box, and can be made the night before your long ride.

Ingredients

  • 300g short-grain sushi rice (uncooked)
  • 1 tsp salt
  • 2 tbsp rice wine vinegar (or white wine vinegar)
  • 1 tsp sugar
  • 100g cooked bacon or smoked salmon, finely chopped
  • 2 tbsp soy sauce or tamari
  • Nori sheets (optional, for wrapping)

Instructions

  1. Cook the sushi rice according to packet instructions. While still warm, fold in the vinegar, sugar, and salt.
  2. Allow the rice to cool to a comfortable handling temperature (not cold — it should remain slightly sticky).
  3. Mix the chopped bacon or salmon with soy sauce in a small bowl.
  4. Wet your hands with cold water to prevent sticking. Take a handful of rice (about 60-70g), make an indent in the centre, add 1 tsp of filling, then close the rice around it.
  5. Shape into a triangle or oval and press firmly so the ball holds together. Wrap in a strip of nori if using.
  6. Wrap individually in cling film or small zip-lock bags. Store in the fridge for up to 24 hours.

Nutrition Notes

Each rice ball provides approximately 150-180 calories and 30-35g of carbohydrates — comparable to a standard energy gel but with the added satisfaction of real food. Consume one ball every 20-30 minutes during rides over 2 hours. Pair with an electrolyte drink to replace sodium lost through sweat.
