Ultra fuel plan calculator
A whole race plan: per hour, hour by hour, race totals and a rough fuel budget.
How does the ultra fuel plan calculator work?
It runs the full UltraCalcPal calculation: carbs, fluids and sodium per hour, then the race totals, then an hour-by-hour table. On a night race, hours between 22:00 and 04:00 take a little less, because appetite and gut movement slow down at night. The budget shows the rough cost for three ways of fuelling: gels and drink, chews, and real food.
The table stops at 24 hours. For longer races the pattern repeats.
What to do with the plan
Turn the per-hour numbers into products: a typical gel is about 25 g of carbohydrate, so 60 g an hour is about 2 to 3 gels. Print the table or save the page as a PDF and tape it to your pack. For a plan with your aid stations, drop bags and a link to share with your crew, use the UltraCalcPal app.
Frequently asked questions
How accurate is the budget?
It is a rough guide in US dollars using typical shop prices for gels, chews, drink and bananas. Prices vary a lot between brands and countries, so treat it as a ballpark.
Should I eat the same amount at night?
Many runners need less at night and use warm, plain food instead of sweet gels. The tool lowers the night hours by 30 percent for carbs and 20 percent for fluids as a starting point.
Can I use it for a multi-day race?
It plans the first 24 hours in detail. For longer races, repeat the pattern and add real food and rest-stop meals, since gels alone do not last for days.
