About this app

Borner – AI-Powered Trail Running Coach for Your Mountain Goals

Whether you're preparing for your first trail race, an ultramarathon, or a technical mountain race, Borner supports you with a custom-generated training plan, tracked week after week and intelligently adjusted to your progress.

CUSTOM PLANNING
Enter your target race, your current level, your usual training volume, and your weekly availability. Borner generates a progressive plan structured into phases (general preparation, specific preparation, tapering, recovery) and mesocycles, fully adapted to your actual constraints—not a generic program from a template.

TRAIL RUNNING METRICS THAT MATTER
Weekly volume, cumulative elevation gain, intensity per zone, training load, and monotony index: Borner tracks the indicators that truly make a difference in trail running. Understand the impact of each week on your overall preparation and anticipate the risks of overtraining before they occur.

DESIGNED FOR TRAIL AND ULTRA RUNNING
Generalist apps often overlook the specific needs of trail running. Borner natively integrates these features: managing positive and negative elevation gain, adapting to the terrain's technicality, progressively building long runs in the mountains, and managing tapering before your goals. Whether you run in the forest, the mountains, or on alpine trails, your plan reflects the reality of your training.

INTEGRATED AI COACH
Your AI coach analyzes your training plan in real time. It detects inconsistencies in training load from one week to the next, identifies imbalances between different types of sessions, and suggests concrete and well-reasoned adjustments. It's not just a calendar: it's an expert perspective on your entire training program.

CLEAR ORGANIZATION
Navigate between phases, mesocycles, and weeks at a glance. Visualize the logic behind your training plan, understand why each block is structured the way it is, and adjust your schedule in case of unforeseen events—a minor injury, a busy week, or an added prep race.

PROGRESSION TRACKING
View the evolution of your key metrics throughout your training period. Observe the gradual increase in training load, the planned recovery phases, and the final taper. Borner gives you the visibility you need to approach your goal with confidence.

From your first introductory trail run to challenging ultra-distance races, Borner provides you with the tools to progress methodically, without getting lost in the complexity.
