My fuel

Q: What is Hydration preference?

A: This slider allows you to select the proportion of water versus sports drink that you prefer to use in your plan. Note that your fuel choices must match this preference (for example, if you pick 100% sports drink preference, but choose water as fuel, you will be asked to add sports drink).

Q: What if I can’t find my favorite product?

A: We’ve started our database of products with the products from leading manufacturers. We will be adding additional products on a regular basis. Send an email at

Q: Can I enter my own custom or home-made product?
