Pace and heart rate, frame-accurate

Gauges read straight from your GPX or FIT, so the pace and HR on screen match your watch exactly. Show pace as a half-circle, a number, or a rolling bar — your call.

A clean route map

Add a moving map or a full route trace with your position. Go transparent (no tiles) for a minimal look over footage, or pick a dark / light basemap.

Sync once, export clean

Auto-align telemetry to your footage from the file timestamp, or nudge it on the timeline. Export an MP4 — or a transparent WebM to layer the overlay onto an edit. No watermark.

From a 5K to an ultra

Concatenate multiple clips on one timeline; the overlay stays in sync across the whole run, however long.

FAQ

Is the running overlay free?

Yes — completely free, no account, no watermark. Export as many videos as you like.

Which gauges can I show for running?

Pace, heart rate, distance, cadence, elevation, time and a route map — each fully restylable.

Does it show pace correctly?

Yes — pace is read/derived from your GPS track, formatted as mm:ss per km or mile.

Can I use it with treadmill or watch-only runs?

If you have a GPX/FIT with the data (HR, distance, cadence), the gauges will display it even without GPS position; the map just needs position data.

Do I need to install anything?

No — it runs entirely in your browser, on any OS. Your files never leave your device.
