ReliveGPX - GPX recording animator

shagen.me/relive-gpx · github.com/c0dev0id/relive-gpx

Replay a recorded GPX track on a 3D map, with a chase camera that follows the rider and telemetry charts alongside. For anyone who wants to re-watch a ride, run, or route in the browser — no account, no upload, nothing leaves the page.

Features

• 3D chase camera — The map tilts and follows the rider, pacing the camera to the track.
• Speed-colored trail — The route is tinted by speed; a moving boundary reveals it as playback advances.
• Telemetry panel — Live speed, altitude, distance, time, and heart rate / power when the file has them.
• Charts — uPlot speed and elevation plots with a cursor tied to the replay.
• Variable speed — Play at 1×, 2×, 4×, or 8×.
• Drop-in — Drag a GPX file onto the page, or pick one. Routes without timing get synthetic 1 Hz timing.
• Keyless hosting — Uses public Esri imagery, so it runs as a static page with no API keys.
