RaceBottle

RaceBottle – Your race nutrition, perfectly planned.

You know your targets: 90g of carbohydrates per hour, 1,000 mg of sodium, 750 ml of fluid. But how much powder goes in each bottle? How many gels do you need to carry? RaceBottle turns your targets into precise mixing recipes and packing lists — in seconds.

For triathletes, cyclists, and marathon runners

Whether you're preparing for an Ironman or a tough training session — RaceBottle calculates your optimal nutrition strategy and personalizes it based on your weight, intensity, and weather conditions.

What RaceBottle does for you:

- Bottle mixing calculator – Exact powder amount per bottle, with concentration display (too dilute, optimal, too concentrated)
- Gel & salt supplementation – Automatically calculates how many gels and salt capsules you need
- Triathlon phase split – Separate targets for swim, bike, and run
- Aid station integration – Accounts for gel and water stations on course, reducing what you need to carry
- Mixing Assistant – Step-by-step guide to filling your bottles
- Product library – 19 brand-name products pre-installed (Maurten, SiS, Precision Fuel, GU, Tailwind and more), add your own via barcode scan
- Session log & review – Save every session, rate it, and track your trends
- Race & training mode – Two separate modes, each optimized for its purpose

The planning algorithm follows current sports nutrition guidelines: maximum concentration of 8g carbs/100ml, run capped at 60g carbs/h, personalized targets based on body weight and intensity.
