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.

WHAT’S NEW Introducing TED (Trail Efficiency Drift) and the new intelligent kilometer-by-kilometer analysis. TED is a new metric designed specifically for trail running that measures how your efficiency changes throughout an activity, helping you understand the real impact of fatigue across different terrains and elevation profiles. The AI now analyzes each segment of your training using power, GAP, cadence, heart rate, gradient and temperature to deliver much more precise insights into your performance. With this update you can: • Detect when your efficiency starts to drop • Identify muscular and cardiovascular fatigue • Better understand your pacing on climbs and descents • Compare stability and consistency between activities • Get advanced AI-powered kilometer-by-kilometer analysis Also includes: • More trail running-specific insights • Improvements in power and efficiency analysis • More accurate training recommendations • Bug fixes and overall performance improvements Train smarter. Run stronger. Understand your performance like never before.

Introducing Trail Efficiency Drift (TED) — a new metric designed specifically for trail running. TED measures how your efficiency changes throughout a run, helping you understand how fatigue impacts your performance across different terrains and elevations. It gives you a deeper view into pacing, endurance, and effort sustainability in real mountain conditions. Our AI now integrates TED into its analysis, delivering more precise and contextual insights about your workouts — including fatigue detection, pacing strategy evaluation, and performance trends over time. With TED, you can: • Detect when efficiency starts to decline during a run • Better understand fatigue and endurance limits • Improve pacing strategies for races and long efforts • Compare performance consistency across activities This update also includes: • Enhanced AI analysis powered by new performance signals • Improved training insights for trail-specific conditions • Bug fixes and overall performance improvements Train smarter. Run stronger. Understand your performance like never before.
