SIDE-ON REPLAY / A FIXED POINT TO COMPARE01 / THE FOOTSTRIKECatch the brake.
See the gap between where your foot hits and where your hips are—and compare the milliseconds spent slowing down before you push off.

Land.
Roll.
Fly.
That run felt faster.
Now see where you took the brakes off.
Running faster starts with seeing where you lose speed. Landing too far ahead of your hips can check your momentum on every step. RunXn brings a fixed lane marker, footstrike replay and a small pulse in your hand together—so you can spot the braking and feel the rhythm you want to keep, without looking down at a watch.

Stop braking.
Run free.
Film from the side on a treadmill or track lane with a RipTag in frame. Pair the replay with footstrike sensing to explore where your step checks your speed, while a small pacer in your palm gives you a rhythm to follow.
A watch tells you that you slowed down.
RunXn shows you the step that cost you.
SIDE-ON REPLAY / A FIXED POINT TO COMPARE
TOUCH. RESPOND. / EYES UP, RHYTHM ON.02 / THE HAND PACERFeel the pace in your hand.
Keep your eyes ahead. Hold the pacer in your palm: a gentle forward cue when you drop off your target split, and a clean tap when your stride finds its rhythm.
The preview below shows the experience we’re building. It illustrates the timing cues on screen; it does not connect to a camera, footstrike sensor or hand pacer.
Try it / Eight invented runs
A little closer under the hips.
A lot more speed for free.
Move through the eight runs. Watch the braking check shrink as the foot lands closer underneath the runner. These are made-up results to explore—not a promise of a particular pace.

Rig setup & browser support
Use a rig that sends the RunXn reading format ↓. Bluetooth needs the service IDs supplied with its firmware. A battery reading alone cannot drive this stage.
Bluetooth: supported Chrome / Edge browsers on Android, Windows and macOS. USB Serial: supported desktop browsers. Direct USB: compatible devices and browsers only; some boards need OS drivers. NFC Tap In: supported Android Chrome devices and NDEF tags. Safari and iOS can use the preview.
Live mode receives only the rig you choose. Nothing is uploaded or saved by this bridge. The existing preview notices describe the eight invented runs. Live numbers drive the illustrated stride; the force curves remain illustrative. Pairing or tapping a tag does not verify 0.1 mm accuracy or spatial calibration.
Palm commands use the documented byte values and require matching firmware. The rig must stop every cue within three seconds and stop on connection loss. No commands are sent until you enable palm cues and click a feeling.

Where did the numbers come from?
These eight landing, braking, and pace numbers are invented to show how RunXn puts a fixed marker, a footstrike sensor, and a hand pacer together. They were not recorded from a real runner. Landing position and ground time are two clues among many; they do not replace coaching or medical advice.
A forward “pull” describes a touch cue, not a force that propels you. The hand animation previews the rhythm, with optional sound and supported phone vibration. It does not reproduce the directional sensation of a hand pacer. A real session needs suitable sensing and calibration—video alone does not measure braking force.

Put it on
one treadmill first.
One treadmill or indoor sprint lane is all it takes to bring the full loop together: a fixed RipTag marker, footstrike sensing on the deck or shoe, and the directional pacer in the runner’s hand.
For venues, labs and partners: start with one setup and a clear question. Can runners recognise the check, feel the timing and repeat the step they want to keep?
