Artemis 3 is the next generation of our AI training engine. It is a direct evolution of Artemis 2, adding Running Power to our bespoke physiological modeling. By integrating power, the AI can more accurately assess and prescribe effort, especially when running on hills or during short, high-intensity intervals where heart rate lag usually creates 'blind spots'.
Important Note on Running Power: Because Artemis 3 calculates effort using relative power (W/kg), it is vital to understand how your device settings and TrainAsONE profile weight interact. Please read our FAQ on how your device weight setting affects running power to ensure your power data remains accurate.
A Note on COROS Devices
COROS have to date not permitted TrainAsONE access to their API. Unfortunately, certain intermediary services (e.g. Strava) used to automate syncing your COROS activities to TrainAsONE strip all but essential data out of activity recordings before passing them on. This includes power data. Consequently, if you use a COROS device and rely on an intermediary sync service, Artemis 3's running power features will not receive the data they need to function correctly.
If you are unsure whether your power data is being received correctly by TrainAsONE, please contact our support team and we will be happy to verify it for you.
How do I get access? As of May 2026, Artemis 3 is in a limited, very early preview stage. We are currently rolling it out to a small, select group of users with compatible power-sensing devices. If you’d like to be considered for the preview, please contact our support team.
