UV Load™ by Pelotan

You measure power. Heart rate. Sleep. But you haven’t been able to measure UV load - until now.

Sun exposure isn't a health footnote, it's an under-appreciated performance variable. It accelerates fatigue, impairs sweat efficiency, raises core temperature, and disrupts recovery. Whereas UV Index reflects a single point in time, UV Load by Pelotan tells you the actual impact of your UV exposure. And it delivers that impact score for each session as well as cumulatively over time. UV Load by Pelotan is calibrated against ARPANSA risk thresholds and is anchored to peer-reviewed exercise physiology. It is a measurement, not a marketing claim. When you measure UV Load, you can manage it for optimal performance.

Here’s how it works:

1. Connect the UV Load by Pelotan app to your Strava account. The app automatically picks up each new outdoor activity, plus any from the last 5 days to help build your baseline.
2. For each session we fuse your route and data including the hour-by-hour UV index, cloud cover and elevation into a single UV Load score from 0–100. Think of it as a Whoop strain score but for UV exposure.
3. See per-session impact and weekly cumulative strain with a push notification the moment a new activity is analysed. Your UV Load metrics will appear in each of your connected Strava activity files.

With this full UV Load picture, you can track your performance and recovery - and adjust when you train and how you can minimize biological impact from debilitating UV Load.

UV Load™ is brought to you by Pelotan - the world’s best sports sunscreen - and is not affiliated, endorsed, or associated with Strava, WHOOP, or any other brand. UV Load is a Training Load–style metric we developed. Nothing in the app should be considered medical advice.
