How to Plan Your Race Strategy

Calculate the optimal pit stops and fuel load for any race:

1

Set Race Format

Choose between timed race (e.g., 60 minutes) or fixed laps (e.g., 50 laps). Formation and cooldown laps are added automatically.

2

Enter Your Pace

Input your average lap time in MM:SS format. Use your practice or qualifying pace for accurate calculations.

3

Configure Fuel Settings

Enter fuel consumption per lap, tank capacity, and select your unit (liters, gallons, or kg).

4

Review Your Strategy

See total laps, pit stops needed, fuel per stint, and the optimal pit window. Adjust strategy mode for different race situations.

Features

Three Strategy Modes

Balanced, Fuel Save (-3% consumption), or Aggressive (+3% consumption) to match your race situation.

Visual Stint Breakdown

See exactly how many laps and how much fuel you need for each stint of your race.

Optimal Pit Window

Know exactly when to pit for maximum efficiency based on your tank range and race distance.

Shareable Configurations

Save your strategy in the URL. Perfect for team endurance events or comparing setups.

Frequently Asked Questions

How does the fuel calculator work?
Enter your race duration or laps, average lap time, and fuel consumption per lap. The calculator determines how many pit stops you'll need based on your tank capacity, then distributes laps across stints evenly for optimal strategy.
What do the strategy modes do?
Balanced mode uses your exact inputs. Fuel Save mode simulates lift-and-coast driving (2% slower lap times, 3% less fuel). Aggressive mode simulates pushing harder (2% faster lap times, 3% more fuel). Choose based on your race situation.
What is the pit window?
The pit window shows the optimal lap range for your first pit stop. The 'ideal' lap accounts for pit stop time loss and distributes race distance evenly. Pitting within this window maximizes your strategy efficiency.
How much safety margin should I use?
We recommend 1-2 laps of safety margin for most races. This accounts for fuel map changes, safety cars, or unexpected fuel consumption. For longer races or variable conditions, consider 2-3 laps.
What are formation and cooldown laps?
Formation laps occur before the race start (pace laps). Cooldown laps occur after the checkered flag. Both consume fuel but don't count toward race distance. Include these for accurate fuel calculations.
Can I limit my stint length?
Yes! Use the 'Max Stint Length' option in Advanced settings. This is useful for endurance races with driver swap requirements, or when tire degradation limits your stint length more than fuel.
