  • Always consult a qualified physician before beginning any new training program, especially if you have pre-existing health conditions.
  • Ultrarunning and trail running carry inherent physical risks. You participate at your own risk.
  • Our AI recommendations are based on data you provide and general coaching principles. They are not a substitute for a qualified human coach or medical professional.
  • VB Digital Ventures LLC is not liable for any injury, illness, or adverse outcome resulting from following coaching recommendations on this platform.

6. Data You Provide: Profile & Preferences

To personalize your experience, we ask you to provide athlete profile information including fitness level, race history, nutrition preferences, body metrics, terrain preferences, and budget ranges. By providing this information you acknowledge:

  • Profile data is used to personalize coaching recommendations and training plans.
  • Budget and spend range data is used only for aggregate, anonymous sponsor-matching analytics, your individual data is never shared with any sponsor or advertiser.
  • Body metrics (weight, height, age) are used only for personalized nutrition and training calculations.
  • You may update or delete any profile data at any time from your Profile page.
  • Providing optional profile fields makes coaching recommendations more accurate and personalized.

7. Third-Party Integrations

Our platform integrates with third-party services including intervals.icu, Strava, and COROS, and may add additional data vendors in the future. Your use of connected third-party services is subject to those services' own terms and privacy policies. We are not responsible for the practices of third-party services. You may disconnect any third-party integration at any time from your account profile.

7a. Data Use Limitations for Connected Services

Our integration with Strava is governed by Strava's API Agreement. In compliance with that agreement, Strava activity data accessed through our platform is used solely to display your own activity history to you within your personal account. Strava activity data is not processed by, transmitted to, or used as input for any artificial intelligence or machine learning system. AI coaching recommendations on ultrarunning.ai are generated from data you provide directly or through other connected services such as intervals.icu or COROS. By connecting your Strava account you acknowledge and agree to this limitation. Our integration with intervals.icu is two-way: we pull your activity and wellness data to power coaching, and, only when you explicitly opt in via the "Push to intervals.icu" toggle in your Profile (off by default), we may write planned workouts back to your intervals.icu calendar. We never modify your intervals.icu data unless you enable this opt-in setting. By connecting your intervals.icu account you acknowledge and agree to this two-way sync behavior.

8. Subscription and Payments

  • Free tier features are available without payment.
