What’s New in TrailStats Custom segments: mark a start and an end point on the elevation profile to see the details of any section (pace, elevation, grade, VAM, heart rate, power and more). Segments are saved with the workout, and you can reopen or delete them anytime. AI segment comparison: the AI analysis now includes a section comparing the segments you marked. A larger elevation profile that’s easier to explore with your finger or the slider. Map and weather for Apple Health workouts, just like with Strava. Better trail detection for Apple Health workouts: elevation gain is now calculated correctly from the GPS route. Clearer automatic names for Apple Health workouts, e.g. “Trail - 8.89km - 545D+”. More reliable Strava uploads: the app checks your Strava permissions when you turn on uploads and asks you to authorize them if needed. If automatic uploads are paused, you’ll see a prompt to reconnect, and pending workouts are uploaded afterwards. Workout details now load much faster. Bug fixes and stability improvements.

TrailStats now lets you choose your data source: sync your activities from Strava or directly from Apple Health (HealthKit). If you use Apple Health, you can upload your workouts to Strava manually from the activity detail or automatically as soon as you finish them, starting from the day you turn it on. TrailStats checks Strava first, so the same workout is never published twice. This version also includes general improvements: activity details always load from their original source even after switching, your race results stay linked to your goals and the widget, upload confirmations and errors are now shown clearly, and settings give better visual feedback when saved.

Thanks to the growth of our European community, TrailStats is now also available in German, French, Dutch, and Portuguese. We’re continuing to make it easier for more runners to analyze, train, and enjoy their trails in their own language.

What’s New in This Version • TrailStats now supports iPad! Access your analyses and statistics on a larger screen, with improved sync across iPhone, iPad, and Mac. • New Preparation Status in Training Processes. Quickly see your cycle’s timeline progress, days remaining, and the key signal to monitor. • New Trail Profile. Identify your current reference for climbing, descending, endurance, and efficiency within each training process. • Improved process reports for sharing with your coach: Technical report with training load, athlete response, trail specificity, comparison with the previous block, and objective observations. Complete report with an optional AI appendix. Short summary optimized for WhatsApp. • New intelligent performance radar. The chart now uses a dynamic scale based on your last 30 days of training: The outer edge represents your best recent performance for each metric. The center represents your lowest performance during that period. The scale adapts automatically for metrics where higher is better, such as VAM or Normalized Power, and metrics where lower is better, such as Pace or GAP. • Improved synchronization, performance, and stability.

Your AI coach is now more personal than ever. Add context before every AI analysis Provide notes about your workout before generating the analysis. Include details such as nutrition, sleep, terrain, weather, perceived effort, equipment, or anything else that helps AI better understand your performance and deliver more meaningful insights. Beautiful Post-Race Reports Capture everything that mattered after race day. Record your sensations, strategy, nutrition, lessons learned, and key takeaways in a beautifully formatted Markdown report that you can revisit before future events. Smarter Training Process Coach The Coach now understands how much time remains until your goal race. It continuously evaluates your completed training sessions and provides personalized guidance on your preparation, highlighting what’s going well and what still needs attention. This update also includes performance improvements, bug fixes, and a better overall experience.

Trail preparation analysis is now smarter and more accurate. • Road training is now included in preparation statistics and race readiness analysis. • Road sessions are automatically separated into: * Z1–Z2: Aerobic base and endurance development. * Z3–Z5: Threshold, speed, and high-intensity work. * Improved balance assessment between mountain-specific training and road training. * More accurate preparation reports by considering both trail-specific workload and complementary road fitness. * Better identification of training strengths, potential gaps, and race-specific readiness. This update provides a more complete picture of your training, recognizing the contribution of both trail and road running to overall performance.

Improved analysis accuracy and clarity. The radar chart now displays efficiency stability instead of efficiency loss, making results easier to interpret. We also refined race time estimation with a new mathematical model that delivers more realistic predictions for courses with elevation gain. Refining key segments with filters to make them more useful, and enhanced weather data to better understand races.
