Last updated: 2026-09-29

The service

ChallengeUS generates training plans and adapts them to your data with declared rules and, if you enable it, with an AI-based conversational coach. Proposals are suggestions: you decide whether to apply them. Professional coaches in the community may review and confirm plans.

Not medical advice

Content does not replace the advice of a physician or health professional. See a doctor before starting a training programme and in case of pain, illness, pregnancy or cardiovascular conditions. If the app suggests you stop, stop.

Account and acceptable use

You must be at least 16. You are responsible for your credentials. Do not use the service for unlawful purposes, to extract other users' data or to overload the systems. The local Garmin connector uses your credentials on your own computer, under your responsibility and Garmin's terms.

Beta, availability and changes

The service may change, be interrupted or contain errors. We may change features and these terms with notice in the app. You can delete your account at any time.

Liability

To the extent permitted by law, ChallengeUS is not liable for indirect damages or damages arising from the use of the plans, from incorrect third-party data (Garmin, Strava) or from service interruptions. Nothing in these terms limits your statutory consumer rights.

Law and jurisdiction

Swiss law, courts of Zug. Mandatory consumer rights of your country of residence remain unaffected. Contact: info@challengeus.com.
