The fastest egg hatchers in Pokémon GO aren’t the ones who walk the most — they’re the ones who manage their incubators and Adventure Sync correctly. Knowing the speed cap and getting your incubator priority right can cut your effective hatching time nearly in half. Here’s everything you need to know.
Egg Types and What’s Inside
There are five standard egg distances in Pokémon GO, plus Adventure Sync-exclusive rewards. Egg pools rotate with seasons and events, so exact contents change — but the categories are stable.
| Egg Type | Distance | Notable Pokémon / Use |
|---|---|---|
| 2 km | 2 km | Cleffa, Igglybuff, Smoochum, Dunsparce, Wimpod, Tadbulb — great for quick candy and XP |
| 5 km | 5 km | Munchlax, Sizzlipede, Fidough, Snom — moderate value, common drop from PokéStops |
| 7 km (Gift) | 7 km | Alolan and Galarian regional forms — Galarian Meowth, Galarian Corsola, Alolan Diglett, Hisuian Sneasel; only obtained from opening friend gifts |
| 10 km | 10 km | Deino, Dreepy, Charcadet, Tinkatink, Honedge — highest stardust on hatch, rarest Pokémon |
| 12 km (Strange) | 12 km | Dark-type hatches: Sandile, Vullaby, Shroodle, Pancham, Salandit, Varoom — only obtained from Team GO Rocket leaders |
Adventure Sync also has its own exclusive 5 km and 10 km egg pools. The AS 10 km pool includes Gible, Goomy, Dreepy, and Turtonator — some of the best hatch-exclusive Pokémon in the game.[1]
Note: egg pools rotate with events and seasons. Always check a current source like Leek Duck for the live pool.
Adventure Sync: The Foundation
Adventure Sync is what makes passive egg hatching possible. When it’s active, the game reads step and distance data from your phone’s health platform even when the app is completely closed — no GPS drain, no screen on.[2]
How to enable it:
- Open Pokémon GO → tap your avatar → Settings → toggle Adventure Sync ON
- iPhone: connects to Apple Health — grant Read access for Steps and Active Energy in iPhone Settings → Privacy & Security → Health → Pokémon GO
- Android: connects to Google Fit or Health Connect — grant Physical Activity permission and set Pokémon GO to Unrestricted under battery optimisation
Weekly rewards reset every Monday at 9:00 AM local time. The key thresholds are:
- 25 km — 3,000 Stardust + items
- 50 km — 10,000 Stardust + Rare Candy + chance at a 5 km or 10 km AS egg
The 50 km threshold is the main target for most players. Hitting it weekly adds up to 520,000 Stardust per year just from Adventure Sync. A common problem: Adventure Sync stops tracking if your phone’s battery saver mode aggressively kills background processes. Check your phone’s battery optimisation settings — Pokémon GO needs to be excluded from aggressive restrictions.
The Speed Cap
Pokémon GO only counts movement below roughly 10.5 km/h toward egg distance. Above that speed, the game ignores the distance entirely — which is why driving with the app open barely hatches eggs.[3]
What works:
- Walking — always counted, ideal pace
- Cycling at moderate pace — the sweet spot: covers distance fast enough to be efficient without going over the cap. Stick to a casual pace and most of it counts
- Treadmill — works perfectly; Adventure Sync reads from the pedometer, not GPS, so treadmill steps count even with no GPS movement
What doesn’t work: driving, trains, planes. GPS speed is too high and the game filters it out. Adventure Sync uses the pedometer sensor rather than GPS, so it’s harder to accidentally exceed the cap while walking — but deliberate spoofing or driving won’t register.
Incubator Strategy
This is where most players leave efficiency on the table. You always have one infinite orange incubator — it never breaks. Blue single-use incubators and Super Incubators are finite resources purchased with Pokécoins or earned from rewards.[4]
The Super Incubator hatches eggs at 1.5× speed: a 10 km egg hatches in approximately 6.7 km instead of 10 km. That’s a 33% distance saving on your most valuable eggs.
You can hold a maximum of 12 eggs at once across all incubators.
The correct incubator priority:
- Infinite orange incubator → always put 2 km eggs. They hatch fastest, freeing the incubator slot for the next egg as quickly as possible. This is the cardinal rule.
- Blue single-use incubators → 10 km and 12 km eggs only. These are your highest-value hatches — they deserve the investment. Never waste a blue incubator on a 2 km or 5 km egg.
- Super Incubators → 10 km and 12 km eggs. Maximum efficiency gains on the longest walks. Using a Super Incubator on a 2 km egg saves you 0.67 km — meaningless. Using it on a 10 km egg saves you 3.3 km — significant.
During hatch events with reduced distances (common during Community Days and special events), 2 km eggs can hatch in just 1 km. During these windows, cycle through 2 km eggs rapidly with the infinite incubator — it’s the fastest way to bulk-hatch for XP and candy.
When your egg bag is full (12 slots), you stop receiving new eggs from PokéStops. Hatch your lowest-value eggs first to open up slots for potentially better drops.
Maximising Weekly Adventure Sync Rewards
The 50 km weekly threshold is the target. Some practical approaches to hit it consistently:
- Don’t rely on Adventure Sync alone — walking with the app open counts the same distance and also lets you catch Pokémon, spin stops, and raid. Active play sessions are the most efficient use of your time.
- Check your weekly progress in the Today tab — the weekly distance ring shows exactly where you are. If you’re at 47 km on a Saturday, a short walk tips you over the threshold.
- Open the app before Monday 9 AM to sync your steps and claim rewards. If you skip that sync, the week resets without paying out.
- The 50 km AS egg reward pool overlaps with the standard 10 km pool — Gible and Goomy are the standout targets.

Common Mistakes
- Not enabling Adventure Sync at all — the most common one. A huge amount of passive distance goes uncounted.
- Putting 10 km eggs in the infinite incubator — this wastes its always-on nature on a slow egg when it should be cycling through 2 km eggs constantly.
- Driving thinking it counts — it doesn’t past the speed cap. You’ll accumulate almost no egg distance in a car.
- Ignoring the 50 km weekly threshold — players who hit 25 km but not 50 km leave 7,000 Stardust on the table every week.
- Filling blue incubators with 2 km eggs — a wasted use of a finite resource that should go on your rarest hatches.
- Holding a full 12-egg bag — if all 12 slots are occupied, PokéStops can’t give you new eggs. Hatch the low-value ones to stay open to better drops.
Conclusion
Hatching eggs faster in Pokémon GO is a system, not just a function of how far you walk. Enable Adventure Sync correctly, respect the speed cap, and follow the incubator priority — infinite on 2 km, blue and Super on 10 km and 12 km. Hit 50 km weekly. Those habits compound over time into far more hatches, more stardust, and better Pokémon than players who just walk aimlessly with eggs in random incubators. Egg hatches give random IVs within a range, too — check our IVs Explained guide to know what you’re actually looking for when that hatch screen appears.
Walking distance also counts toward buddy candy — see our buddy guide for which Pokemon are worth walking and how the Best Buddy system works.

I've been playing video games for over 20 years, spanning everything from early PC titles to modern open-world games. I started Switchblade Gaming to publish the kind of accurate, well-researched guides I always wanted to find — built on primary sources, tested in-game, and kept up to date after patches. I currently focus on Minecraft and Pokémon GO.
