Run Free, Train Private.
YOUR TRAINING. YOUR DEVICE.
MtnRnr is built to keep your data where it belongs: on your device. No account required. No cloud profile. No data brokering. Your workouts, plans, shoes, and training history stay local unless you choose to export them.
BUILT FOR TRAIL & ULTRA RUNNERS
Whether you're targeting your first trail race or a 100-mile ultra, MtnRnr adapts to your goals, fitness level, and available schedule. Generate science-based training plans, review your running history, and get actionable pace guidance — all tailored to you.
RACE COURSE IMPORT — PLAN FOR YOUR EXACT RACE
Upload the GPX file of your goal race and MtnRnr will build your training plan and race-day pacing around that specific course. Real elevation profiles, real terrain, real distance — not a generic template. If you're toeing the line at a specific race, prepare for that race, not an approximation of it.
HEALTH APP INTEGRATION
MtnRnr reads authorized Apple Health data — workouts, routes, heart rate, VO2 max, sleep, steps, and activity metrics — to power training insights, fatigue estimates, and personalized recommendations. MtnRnr never writes data back to Apple Health and never shares your health data with third parties.
RUNNING SCORE & PACES
Unlock your Running Score from real race efforts and dial in science-based training paces across all effort levels — easy, tempo, threshold, and race pace.
TRAINING PLANS
Build customized plans around your goal race, available training days, and current fitness. Import your race's GPX course file and your plan will be shaped around that specific race — its distance, elevation, and terrain demands — so every training block has a purpose.
PERFORMANCE INSIGHTS
Monitor training load, fatigue, and fitness trends over time. Readiness-style guidance helps you understand how your body is responding — before it becomes a problem.
RACE DAY TOOLS
Prepare for your exact goal event with pacing utilities built around your imported race course. Review the real elevation profile, plan your effort segments, and walk to the start line knowing you trained for this specific race — not a generic one.
SHOE TRACKING
Add your running shoes, assign them to workouts, and monitor mileage so you always know when it's time to rotate or replace.
STRENGTH LOGGING
Log support sessions alongside your running for a complete record of your training week.
FILE IMPORT
Import GPX, FIT, and TCX workout files from Garmin, Suunto, COROS, and other devices through Apple Health or direct file import.

• No account or sign-in required
• No advertising or third-party data sharing
