Steal an Egg Every Biome: Minimum Speed Needed

This calculator works out the minimum speed you need to maintain in order to steal an egg from every biome in a typical open-world survival game, given the total distance you must cover and the time limit you have. You enter the finish time and the total distance, and it returns your required average pace and average speed. The result tells you the bare minimum pace you cannot drop below if you want to collect every egg before the timer runs out.

Formula

The calculator uses two basic relationships between time, distance, and speed. The first is the pace, which is the time it takes to cover one unit of distance:

Pace (min/km) = Total time (min) ÷ Total distance (km)

The second is the average speed, which is the distance covered per unit of time:

Speed (km/h) = Total distance (km) ÷ (Total time (min) ÷ 60)

Where:

• Total time (t) is the time limit you have, in minutes.
• Total distance (d) is the sum of all distances you must travel to visit every biome and steal the egg, in kilometers.
• Pace is expressed in minutes per kilometer (min/km).
• Speed is expressed in kilometers per hour (km/h).

The two results are reciprocals of each other when converted properly: a pace of 5 min/km equals a speed of 12 km/h (because 60 ÷ 5 = 12).

Worked Example

Using the default values from the calculator: a finish time of 50 minutes and a total distance of 10 kilometers.

Step 1: Calculate the pace.

Pace = 50 min ÷ 10 km = 5.00 min/km

Step 2: Calculate the speed.

Speed = 10 km ÷ (50 min ÷ 60) = 10 km ÷ 0.8333 h = 12.00 km/h

So with the defaults, you need to maintain an average pace of 5 minutes per kilometer, which is an average speed of 12 km/h. If you go any slower, you will not finish in time.

What “Every Biome� Means in Practice

In games that feature a “steal an egg from every biome� challenge, the biomes are usually distinct regions such as desert, forest, tundra, swamp, ocean, and volcanic areas. The total distance is not just the straight-line distance between eggs; it includes the path you actually travel, which is almost always longer because of terrain, obstacles, and the need to return to a base or a central point. When you measure the distance for the calculator, you should use the real in-game distance you expect to cover, not the map’s straight-line distance. Many players underestimate this by 20–50%.

The time limit is typically set by the game’s challenge timer, but it can also be a self-imposed goal. If the game does not give a timer, you can set your own target based on how long you want the run to take. The calculator works the same way either way.

How to Read the Result

The first output, the pace, is the most useful for in-game navigation because most games show speed in units per minute or per second. A pace of 5 min/km means you need to cover 1 kilometer every 5 minutes. If you have a waypoint or distance marker, you can check whether you are on track by comparing your actual time at each marker to the required pace.

The second output, the speed, is helpful if your game displays speed in km/h or miles per hour. If your game uses miles, convert the distance to miles first (1 km = 0.621371 miles) and enter that number. The calculator does not convert units automatically, so you must be consistent.

If your actual speed is above the required speed, you have a buffer. If it is below, you will need to find a faster route or cut out detours. A good rule of thumb is to aim for 10–15% faster than the minimum to account for unexpected delays like combat, climbing, or getting lost.

Common Mistakes and How to Avoid Them

• Mixing up units: If you enter distance in miles but time in minutes, the pace will be in min/mile, not min/km. Always convert to the same unit system first.
• Using straight-line distance: The actual path you run is rarely a straight line. Use a route planner or measure the path you intend to take, not the map’s direct distance.
• Ignoring vertical distance: Climbing hills or mountains takes extra time. If your route has significant elevation change, add 10–20% to the distance or time to account for it.
• Rounding too early: If you round the pace to the nearest whole number, you might think you have more time than you do. Keep at least two decimal places when checking your progress.
• Forgetting to include the return trip: If you need to bring the eggs back to a central location, the distance doubles. Make sure your total distance includes every leg of the journey.

Limits of This Calculation

This calculator assumes a constant speed across the entire route. In reality, you will move faster on flat ground and slower in water, sand, or uphill sections. The result is a minimum average, not a per-section requirement. If you know that certain biomes are slower, you can plan to move faster in the faster biomes to compensate.

The calculator also ignores time spent fighting, gathering, or solving puzzles. If your challenge includes combat or other mandatory actions, subtract that time from the total time before entering it. For example, if you have 50 minutes total and expect 10 minutes of fighting, enter 40 minutes as the finish time.

Finally, the formula assumes you can move continuously. If the game has stamina mechanics that force you to stop, you need to factor in rest time. A common approach is to increase the total time by the expected rest percentage, or to increase the distance by the extra backtracking caused by stopping.

Choosing a Realistic Target

If you are new to the challenge, start with a generous time limit and then tighten it as you learn the route. For a first attempt, add 50% to the minimum time you think you need. After you complete the run, look at your actual finish time and use the calculator to find your real average pace. That becomes your baseline for the next attempt.

For experienced players, the minimum speed is often dictated by the game’s fastest movement option. If the fastest mount or movement ability gives a top speed of 20 km/h, but the average required is 15 km/h, you have a comfortable margin. If the required speed is 19 km/h, you will need to be near your top speed the entire time, which is rarely sustainable.

You can also use the calculator to compare different routes. Enter the distance and time for route A, then for route B, and see which requires a lower average speed. The route with the lower required speed is generally easier, even if it is longer, because it gives you more buffer.

Frequently Asked Questions

What if my game shows speed in miles per hour instead of km/h?

Convert your distance to miles before entering it. For example, if your route is 10 km, enter 6.21 miles. The speed output will then be in mph, and the pace will be in min/mile. The formula works the same; only the unit changes.

How do I measure the actual distance of my route?

Most games have a map with a distance tool or waypoint system that shows the distance to a marker. If not, you can use a third-party map tool that overlays the game world, or you can time a test run over a known flat distance to estimate your speed and then multiply by the time. For a rough estimate, count how many in-game meters you cover in 10 seconds and multiply by 6 to get meters per minute.

Can I use this calculator for a challenge without a time limit?

Yes. Set a self-imposed time limit that you want to beat. The calculator then tells you the minimum speed needed to hit that target. If you just want to know your average pace after the fact, enter your actual finish time and distance.

What is a good buffer to add to the minimum speed?

Add 10–15% to the required speed to account for mistakes, combat, and terrain. For example, if the calculator says 12 km/h, aim for 13.2–13.8 km/h. If you are using the pace, subtract 10–15% from the pace value (so a 5.00 min/km pace becomes about 4.35 min/km).

Does the calculator account for different movement speeds in different biomes?

No. It assumes a constant speed. To handle variable speeds, break your route into segments, calculate the time for each segment using the expected speed for that biome, sum the times, and then enter that total time and the total distance. This gives a more accurate overall average.

Why is my actual pace slower than the calculator’s minimum even though I’m running?

You are likely stopping more than you think, or taking a longer path than you measured. Record a test run and compare the actual distance traveled to the planned distance. Also, check if you are slowing down on uphill or rough terrain more than expected. Recalculate with a longer distance or a shorter time limit.
