Coach Fartlek

Coach Fartlek is a proactive AI running coach for serious recreational and marathon runners. Instead of waiting for you to open the app, the coach reaches out on its own: after a workout syncs, before a key session, and when your recovery data says you should ease off.

It builds a full training plan in three layers. A macro plan covers the season toward your goal race, a meso plan sets four-week blocks with the right load curve, and a micro plan turns that into this week's concrete sessions, adjusted to your calendar and how you are recovering.

Connect your Intervals.icu account and your runs sync automatically from your watch (Garmin, Polar, Coros, Suunto and more). The coach analyzes every run, including pace, heart rate and intensity, and gives you feedback the same evening. It remembers your history, so the advice builds on what you have actually done.

What you get:

• A personal weekly running schedule built around your goals and races
• Proactive check-ins after runs, before key sessions, and when recovery should come first
• Recovery-aware planning from resting heart rate, HRV and training load
• Race focus from 5K and 10K to half marathon and marathon
• A training journal that the coach reads and remembers

Coach Fartlek is for runners who train consistently and want a coach who understands both training and real life, whether you are chasing a sub-3 marathon, your first half marathon, or a faster 10K.

Free to start, with optional Pro and Elite subscriptions. Works in English and Swedish (the coach speaks several languages).
