Beta

Ultra Fuel Planner is currently in beta. Plans should be tested in training before race day.

Route-aware fuelling planner

Plan your fuelling for
the route you're actually running.

Upload your GPX file, enter your past race data, and add the fuel products you'll carry. The planner builds a fuelling schedule matched to your route and a carry plan between each checkpoint.

Free. No account needed.

What the planner helps you figure out

The planning questions that matter for a long race.

How much to eat per hour

A recommended range based on your race duration and prior runs — not a number from a generic table. The planner selects a working target within that range to build your schedule around.

Where fuelling gets difficult

Steep climbs, long gaps between aid stations, and technical descents change what you can eat and when. The plan works around them.

What to carry between each checkpoint

A carry list for each section, using the specific gels, drink mixes and food you plan to use on race day.

A race plan you can actually follow.

The planner produces a race card you can print and carry in your vest. It breaks down what to eat, when to eat it, and what to carry between each aid station.

  • Fuelling schedule: What to eat at each point, matched to the terrain you'll be on.
  • Carry plan: What to pack between each aid station — items, quantities and approximate fluid.
  • Hydration guidance: A practical drinking range, adjusted for expected conditions.
  • Printable race card: A simple format you can print, fold and carry on race day.

How it works

Four steps. Your data, your route, your plan.

01

Add your past runs

Enter a few past races or long runs — distance, time, elevation. The planner uses these to set realistic targets for your event.

02

Upload your race GPX

Drop in your GPX file. The planner reads the elevation profile and breaks the route into terrain segments.

03

Add your fuel products

Enter the gels, chews, bars and drink mixes you plan to use. Mark your aid stations and what they offer.

04

Generate your race plan

Get a fuelling schedule matched to your route, a carry plan for each section, and a printable race card.

Not a calorie calculator.

What makes this different from a spreadsheet or a generic fuelling guide.

Calibrated from your past runs

Enter a few prior races or long training runs. The planner uses them to set carb and fluid targets you can realistically hit — not numbers from a generic table.

Reads your GPX file

Your elevation profile tells the planner where the route gets hard — long climbs, technical descents, remote sections with no aid. Format recommendations adjust to what's practical on each terrain.

Uses your actual products

You enter the specific gels, drink mixes and bars you own. The plan is built around those products, not theoretical grams of carbohydrate.

Maps your aid stations

Mark where the checkpoints are and what they offer. The planner builds a carry plan for each section and tells you what to restock.

Outputs a race card

The result is a simple printable card — not a spreadsheet. Fold it up and carry it in your vest pocket.

Race day is not the time to figure out fuelling.

Build a practical race strategy from your own data and your actual course. Know what to carry, where fuelling gets harder, and what to restock at each checkpoint — before you toe the line.
