Fluid & Multiple Transportable Carbohydrate Calculator

After answering the same questions a few times over the years, we decided to throw together a little nutrition calculator. Its based on some basic principles of sports nutrition, which are easy enough to understand, but in practice, are quite difficult to calculate. The calculator below is designed for athletes of all abilities, from the weekend warrior, all the way up to ultra-endurance athletes.

The idea is that you tell us what you put in your bottle, and how long it takes to drink it. Simple enough. We then do a few calculations and let you know how well your mix compares with best practice.

Most people will just be adding water and R-Line, but we have added a box to include some R-Line Reload Gel as well. This is for the really advanced athletes, especially the ultra endurance athletes who have a higher risk of gastrointestinal upset and want to really fine tune their glucose to fructose ratio.

We’ve put in some numbers to start with. If you are too far astray you will get some warnings pop up. You’ll find that there is a fair bit of flexibility for you to work with.

Once you have your numbers in place, you can check out the articles at the bottom of the page, which might give you a little more insight into your race day nutrition strategy.
