Athletica is thrilled to announce a major new integration with Intervals.icu, a powerful platform for analyzing endurance training data. This long-requested feature enables seamless synchronization between Athletica AI and Intervals.icu, making it easier than ever for athletes to centralize and analyze their training.
Why This Matters
Athletica AI provides science-backed, adaptive training plans designed to optimize your endurance performance. Intervals.icu is a widely used analytical platform that offers deep insights into fitness trends, historical data comparisons, and performance metrics. By integrating the two, athletes can now enjoy the best of both worlds—smart training guidance from Athletica and robust analytical tools from Intervals.icu.
For many users, Intervals.icu serves as a “one-stop” storage hub for all their training activities, pulling data from various platforms like Garmin, Zwift, and Wahoo. With this integration, your Athletica training plan and wellness data will now automatically sync with Intervals.icu, eliminating the need for manual data entry.
Key Features of the Integration
✅ Automatic Sync of Planned Training: Your Athletica training plan (up to two weeks in advance) will now be automatically synced with your Intervals.icu calendar.
✅ Wellness Data Integration: Intervals.icu wellness records will be auto-synced hourly for today and yesterday, and daily for the past week—ensuring your HRV, HR, and recovery data are always up to date.
✅ Unlock HRV Sensor Insights with AI: Already tracking HRV with Garmin, Oura, WHOOP, Polar, Suunto, HRV4Training, Elite HRV, or Kubios? Now, Athletica’s AI coach can analyze your HRV data and apply best-practice training advice—ensuring smarter, more personalized adaptation.
✅ Sync Athletica Workouts to Zwift via Intervals.icu: While Athletica does not yet have a direct Zwift integration, Intervals.icu does. Now, users can sync their Athletica training plan with Intervals.icu, which then pushes the workouts into Zwift—allowing for a smoother, automated experience when using Zwift for structured training.
✅ A More Connected Ecosystem: This integration allows Athletica users to see their structured workouts alongside other logged activities (e.g., strength training, cross-training, or races), giving a more holistic view of their training.
Why Athletes Wanted This Integration
The demand for Athletica + Intervals.icu integration has been strong within both communities. Users have long praised Intervals.icu for its flexibility, deep analytics, and seamless compatibility with other fitness platforms. Many Athletica users were already manually transferring workouts into Intervals.icu—a tedious task that is now automated.
Here’s what some of our users had to say:
📢 “I currently use Athletica.ai to generate my training and would love to sync to my Intervals.icu calendar.” – Billmtri
📢 “Athletica has very good training plans, but lacks support for other platforms and devices. I’d also prefer to use the analysis power of Intervals.icu. Synching the services would benefit both sides, I think.” – Harlerunner
📢 “Having at least an integration that would allow the option to download a user’s Athletica.ai planned training into their Intervals.icu calendar in a form readable by Intervals would be fantastic!” – Firestop
📢 “The main thing is that I use Intervals.icu as my central storage for activities (Garmin, Zwift, etc.). The other plus would be syncing workouts back to Intervals.icu so I can automatically import them into Zwift.” – Mathijs
How to Enable the Integration
- Go to your Athletica.ai account and navigate to the Settings > Integrations section.

- Your next two weeks of planned training will be automatically pushed to your Intervals.icu calendar.
