The Outrun patch

Continuous lactate monitoring from a skin-mounted biosensor. No finger pricks. No lab stops. Real-time data to your app and watch.

What is the Outrun patch?

The Outrun patch is a wearable biosensor for continuous lactate monitoring during training. It is designed to measure lactate without finger-prick blood tests and stream intensity data to the Outrun app and compatible wearables in real time. It is for informational and training use - not a medical device.

  • Continuous lactate insight during the session, not just a single snapshot
  • Skin-mounted patch connected to phone and watch
  • For athletes and coaches - not medical diagnosis or treatment
