Speed is both travel and a safety margin. The official page tells you to train on the treadmill, then outrun Zone Guardians back to the Safe Zone. A higher number also opens zones whose signs you cannot meet yet.
How training works
Stand on the treadmill. Speed rises only while you are on it, shown as blue shoe pops and the line Running! Press Space / Jump to get off. The Speed per second rate depends on the treadmill level. After a purchase the game confirms it, for example Treadmill upgraded to Lv.3!, and the new rate applies the next time you run.
Two reported cash steps:
| Upgrade | Price | Speed per second |
|---|---|---|
| Treadmill Level 2 to 3 | $770K or 8 Robux | +1.32K to +3.37K |
| Treadmill Level 3 to 4 | $2M or 12 Robux | +3.37K to +21.2K |
Level 4 is a large jump in training rate for a small cash step compared with the pen's later slot prices. That does not mean you should skip a pen upgrade when you are blocked on slots. Buy the treadmill level when the return trip is the thing failing.
A full level curve is not published. Use the price on your board.
Zone numbers to respect
These recommended Speeds are for the first four zones on the path out from the base:
| Zone | Recommended Speed |
|---|---|
| Grass | 5 |
| Forest | 1.5K |
| Mushroom | 67.5K |
| Desert | 650K |
Desert's 650K is posted in front of the green T-rex. Mushroom is marked by an arrow. The jump from Mushroom to Desert is why treadmill Level 4 matters: at +3.37K Speed per second, 650K is a long train; at +21.2K it is much shorter.
Footage has also shown box requirements around 5, 10, 67.5K, 70K, and 1M. Treat those as examples of how wide the gates get. The sign in your server is the number that matters.
A developed HUD example showed Speed 14.2M with a x2.5 multiplier, cash around $1.08B, and income around +$71.4K. That is one late screen, not a target for the first hour.
Three different Speed boosts
Do not mix these up.
- Treadmill level raises Speed gained per second while you train.
- A trail multiplies that treadmill gain. Ocean Wave is 2x gain. It does not set your run Speed to 2x by itself.
- A base button labeled x2 Speed costs 3 Robux. That is separate from the 20-minute 2x Speed on the 3MVISITS code, and separate from trails.
- Friend Boost reads +0% when no friends are in your server.
A short 2x Speed window, including the 20 minutes on 3MVISITS, is useful if you spend it on the treadmill or on a route you have already walked. It is a poor use of the timer to open menus until it expires.
When not to push
If your Speed is under the posted gate, another attempt does not create Speed. Train, place PCs so the pen can pay for the next treadmill level, and come back when the sign is below you with room to spare. Guardians still chase after a successful steal. Meeting the minimum does not make the carry automatic.
