About the UltraCalcPal blog
Practical fuelling guides for ultra runners and the people who crew them.
Why this blog exists
A long race is won and lost on food, fluid and salt, and most plans live in a notes app or in your head. We build UltraCalcPal to turn a plan into hours, bags and stations. This blog covers everything around it: how much to eat, how to test it in training and how to share the plan with your crew.
Who writes it
How the guides are made
Each guide answers one question, in plain words. Numbers come with their ranges and with the sources we used, and none of it is medical advice. When a fact changes, we update the guide and show the date.
A note on UltraCalcPal
UltraCalcPal makes the app that some guides mention. We mention it only where it solves the problem the guide describes, and every guide is useful without it.
