## What is Runkyz?

Run through a 3D desert, around a lake or past the planets without leaving your treadmill. A virtual pacer runs ahead at the pace you choose, and the game shows the speed and incline to set.

WORKS ON ANY TREADMILL
Set your treadmill to the speed and incline on screen. No extra sensor to buy, nothing to pair. Runkyz never controls the machine.

FREE TO START, NO ACCOUNT, NO SUBSCRIPTION
Desert and Wild Ring are free up to 10 km. One purchase unlocks Space and every distance over 10 km, for good.

THREE 3D WORLDS
• Wild Ring: a flat 2 km loop around a lake, with wildlife. Each lap lasts a day, from dawn to night.
• Desert: dunes, temples and pyramids, on flat, rolling or hilly profiles.
• Space: a route through planets and asteroids (full game).
Choose 3 km, 5 km or 10 km for free. The half marathon, the marathon and the 170 km ultra come with the full game.

A PACER TO CHASE
Set a pace and follow the pacer along the route, or run solo. Distance, time and pace stay on screen.

READY-MADE SESSIONS
The Training tab has the 12-3-30 incline walk and the steps that lead up to it, a walk-run plan that builds to 30 minutes non-stop, Yasso 800s, hill repeats, a ramp test and a 5 km time trial. Target paces are calibrated from your own records.

HOW IT WORKS
1. Pick a world and a distance.
2. Set your treadmill to the speed and incline shown.
3. Run. The pacer is ahead of you.

GOOD TO KNOW
Speeds are shown in km/h. Hill sessions need a treadmill with incline. Place your iPhone or iPad on a stable support in front of you.

## Version history (last 3 releases)

### 1.1.1 — 2026-10-09

Space: new ambient sound. A deep, distant rumble replaces the held chord and the bells.

### 1.1 — 2026-10-08

All three worlds have been rebuilt.
• Wild Ring is now a 2 km loop in a valley. Each lap lasts a day: dawn in the pines, night with the fireflies.
• Desert: every run crosses a day, with real dunes, a herd of horses at sunset and foxes at dusk.
• Space: each chapter has its own light, from Earth to the Sun.
• Every world has ambient sound: birds, a waterfall, waves and crickets on Wild Ring; in Desert, a wind recorded in the Atacama.
• 12 badges to earn and a new finish screen.
• A night menu and a new pause screen.
• Runs no longer have built-in music; the menu keeps its own.

The full game is now a one-time purchase that unlocks Space and every distance over 10 km. Desert and Wild Ring stay free up to 10 km. If you installed Runkyz before this update, everything stays unlocked for you.

### 1.0 — 2026-10-08

No release notes.
