Miles

Miles is an iOS running coach for goals ranging from a first 5K to a marathon. Miles Pro builds a week-by-week training plan from current fitness and reshapes it when runs are missed. During runs, it tracks GPS pace and provides audio cues when pace moves off target, with structured intervals, tempo runs, and long runs. After each session, the app gives coaching analysis of what worked and what to change. Plans cover 5K, 10K, half marathon, and marathon goals; treadmill runs can receive structured workouts and post-run analysis. Miles Pro supports Apple Health and Bluetooth heart-rate monitors. The free plan includes iPhone run tracking, goal setting, and a plan preview. Miles Pro Monthly costs $14.99 a month. Miles Pro Annual costs $99.99 a year and begins with a 7-day free trial. The App Store lists compatibility with iPhone running iOS 18.5 or later and Apple Watch running watchOS 11 or later. Miles collects location and health and fitness data, including GPS data and heart rate.

Miles combines adaptive running plans, live pace cues, and post-run analysis across several race distances, including treadmill training. Consider the iOS requirements and the location and fitness data it collects when deciding whether it fits.

Miles is aimed at new runners, people returning to running, personal-best chasers, and marathon trainees. It may suit iPhone users seeking a changing training plan and live pace cues.

Miles is an AI running coach for iPhone that builds training around goals from 5K to marathon. It suits runners who want a schedule that can recover from missed sessions, with spoken pace guidance and feedback after every workout. The free tier is useful for basic tracking and planning, while the complete coaching experience is a subscription.

Overview

Miles covers 5K, 10K, half-marathon and marathon programs, making it relevant to first-time runners, people returning after a break, personal-best chasers and marathon trainees. Its focus is structured running rather than broad fitness logging. Treadmill sessions count toward training, so indoor workouts can still receive structure and review.

Key features

Adaptive training

Miles Pro creates a week-by-week plan from current fitness and reshapes it when a run is missed. That is a practical advantage for runners whose schedules are unpredictable; a fixed calendar is less forgiving. The free plan only provides goal setting and a plan preview, so it cannot replace a complete adaptive schedule.

Live and post-run coaching

During outdoor runs, Pro follows GPS pace and gives audio cues when you drift from the target. Intervals, tempo runs and long runs provide purposeful sessions instead of an undifferentiated mileage log. After each run, the app explains what worked and what to change, giving both newer runners and experienced athletes a concrete next step.

Indoor runs receive structured workouts and post-run analysis as well. Apple Health and Bluetooth heart-rate monitor support are included in Pro, while readiness and training-load features add context for deciding how hard to train. The result is a running-specific coaching set rather than a general exercise library.

Data and privacy

Miles collects location and fitness information such as GPS data, distance, pace, cadence, heart rate and workout time. With consent, anonymised pace and distance data may be shared with an AI/LLM partner to produce coaching insights and recommendations. Miles says transmission uses SSL, access is restricted, and cloud providers use industry-standard encryption. Users can request access, correction, deletion, restriction or portability, object to processing and withdraw consent. Those comfortable sharing detailed training data get richer coaching; privacy-conscious runners should weigh that exchange.

Pricing

The Free plan costs $$0 forever and includes iPhone run tracking, goal setting and a plan preview. It is a sensible way to check the app's approach, but it omits adaptive training, live audio cues, post-run analysis, readiness and training load, and the health-device integrations.

Miles Pro Monthly costs $14.99 a month, billed immediately through the App Store, with no free trial. It includes the full adaptive plan, live pace coaching, analysis, readiness and training load, Apple Health and Bluetooth heart-rate support. Choose it if you need flexibility month to month; it is the most expensive ongoing option.

Miles Pro Annual costs $99.99 a year and begins with a 7-day free trial before App Store billing. That works out to the advertised $8.33/mo and is the better fit for a season-long goal or marathon block, provided you cancel before renewal if you do not want to continue. A Pro one-time offer costs $$69.99 once; its listed price is attractive for avoiding recurring billing, though the offer does not state a term or feature difference.

Platforms

Miles is available on iOS. The App Store requires an iPhone running iOS 18.5 or later and an Apple Watch running watchOS 11 or later.

Who it's for

Pick Miles if you want running plans that adjust to missed workouts, live target-pace reminders and a review after each session, including treadmill training. It is especially suitable for new or comeback runners who need structure and for goal-driven runners preparing for a specific race distance. It is a poor fit for Android users, people seeking a free full coaching plan, or runners unwilling to share location and health data.

Pros and cons

• Pros: Plans adapt when runs are missed, reducing the penalty of an imperfect schedule.
• Pros: Audio pace cues, structured workouts and post-run analysis connect execution with follow-up.
• Pros: Treadmill support and heart-rate integrations keep indoor and sensor-based training in the same program.
• Cons: The free tier stops at tracking, goals and preview content, leaving core coaching behind Pro.
• Cons: It is limited to iOS devices meeting recent operating-system requirements.
• Cons: Coaching depends on collecting detailed location and fitness data, with optional AI-partner sharing.

• APEX is better for logging workouts and meals, unlimited custom routines and a large exercise and ingredient catalog.
• ARDOR is an iOS alternative with one free workout per week and a seven-day full-access period.
• Saga Coach fits users wanting three permanent free workouts, chat access and schedule changes.

Verdict

Miles is a strong choice for iPhone runners who want an adaptive race plan, in-run pace correction and useful post-run direction, especially when treadmill sessions matter. Look elsewhere if you need Android support, a genuinely full free tier or less data-intensive coaching.
