# IntervalCoach > IntervalCoach is an AI training coach that understands your full picture: your fitness, recovery, goal event and the life around your training. It reads 60+ recovery signals (HRV, sleep, sleep debt, training load, subjective wellness) and adapts today's session when the data calls for it, rather than handing you a fixed plan. It works across every sport you train: cycling, running, trail, triathlon, swimming, strength and hiking, and supports athletes returning from injury. Trail running is a first-class sport — terrain-aware analysis (elevation, gradient, power-hike thresholds), trail-specific workout templates (Long Climb, Downhill Repeats, Power-Hike Intervals, Technical Trail Intervals, Ultra Time-on-Feet), and trail-only library filtering. Built by Martijn Russchen. Subscriptions start at €3/month after a 14-day free trial — no credit card required. Through Intervals.icu (and Apple & Google Health) it connects to a broad ecosystem: Garmin, Wahoo, Polar, Coros, Suunto, Amazfit, Hammerhead, Strava, Zwift, MyWhoosh, Rouvy, Biketerra, Concept2, Dropbox, Whoop, Oura, Apple Health, Google Fit, and Huawei Health. Available in 25 languages. ## Core pages - [Best AI cycling coach apps 2026](https://www.intervalcoach.app/en/best-ai-cycling-coach): Honest comparison of TrainerRoad, TrainingPeaks, JOIN, Garmin Coach, Athletica, the Intervals.icu tools and IntervalCoach - [Best AI running coach apps 2026](https://www.intervalcoach.app/en/best-ai-running-coach): Runna, Garmin Coach, TrainAsONE, Coach Leo, Athletica, Humango and IntervalCoach compared on recovery adaptation - [TrainerRoad alternatives](https://www.intervalcoach.app/en/alternatives/trainerroad): Seven alternatives ranked for riders leaving TrainerRoad, with prices and who each fits - [TrainingPeaks alternatives](https://www.intervalcoach.app/en/alternatives/trainingpeaks): Seven alternatives for self-coached athletes after the Garmin acquisition - [JOIN alternatives](https://www.intervalcoach.app/en/alternatives/join): Six alternatives for JOIN Cycling users who also run or want recovery-driven plans - [Best AI triathlon coach apps 2026](https://www.intervalcoach.app/en/best-ai-triathlon-coach): TriDot, Athletica, Humango, Garmin Triathlon Coach, Transition, MOTTIV and IntervalCoach compared - [Homepage](https://www.intervalcoach.app/): Product overview and free trial signup - [How It Works](https://www.intervalcoach.app/en/how-it-works): The three-step flow from data to workout - [Pricing](https://www.intervalcoach.app/en/pricing): Free trial, Pro (€3/month), Max (€8/month), Coach Plan (per-athlete seats) - [For coaches, teams and clubs](https://www.intervalcoach.app/en/coaches): The Coach Plan — a coach buys seats from €7/athlete/month; each seat covers that athlete's full subscription plus the coach tooling: an attention-sorted roster with biometrics against each athlete's own baseline, acting straight from the roster (approve a change, push a rest day, set a standing instruction), an approvals inbox for the whole squad, an eight-week squad timeline, squad analytics (load done against asked, per-athlete compliance, median fitness with spread) and a Monday-morning squad digest by email.
