Fuel guide

Choosing the right fuel for the session.

A simple guide to our sizes and sodium levels, so you can pick what works for your training, racing, and routine.

Session is built to keep fuelling clear, practical, and easy to trust.

Not every session needs the same setup.

Sometimes you want a single serving to throw in a bag. Sometimes you want a pouch that covers weeks of training. Sometimes you need a lower sodium mix for everyday use, and sometimes you want more sodium for hotter days or heavier sweating.

This guide makes it easy to understand the difference.
