Mountain bike telemetry overlay
Give the descent context. Pair your GoPro footage with a Garmin FIT file and Overspeed adds speed, gradient, and heart rate, so a steep line looks as gnarly on screen as it felt.

The data that matters
The channels that make this discipline read on screen, synced to your footage.
GoPro and Garmin, together
Bring your action cam footage and a Garmin FIT file into one project. Overspeed reads speed, GPS, elevation, and heart rate straight from the FIT.
Gradient and elevation
Show how steep the trail really is with a live gradient readout and an elevation profile, the part of a descent a flat camera angle always hides.
Heart rate that tells the story
Overlay heart rate from your watch or strap so the effort behind a climb or a sketchy line is right there on screen.

Frequently asked questions
Can I overlay a Garmin FIT file on GoPro footage?
Yes, that is a core use case. Import the FIT file, load your GoPro clip as a reference, and sync them on the timeline. Speed, GPS, elevation, and heart rate map automatically.
Where does heart rate come from?
Any Garmin FIT (or compatible CSV) that includes a heart-rate channel. Overspeed detects it and you drop it onto a gauge.
Can I create a custom widget for my MTB edits?
Yes. Describe what you want, like a gradient and elevation panel for the descent, and the AI Studio builds it. Tweak every detail and save it to reuse on every ride.
