Your coach reaches out first — after every workout, before key sessions, and when recovery matters. Coach Fartlek is a proactive AI running coach built for serious recreational runners. The coach gets to know you, plans your training, and checks in — just like a real coach would. WHAT YOU GET • Personal planning — A weekly schedule tailored to your goals, races, schedule, and how your body is responding right now. • Proactive coaching — Messages after every workout, before key sessions, and when recovery should take priority. • Smart recovery — Resting heart rate, HRV, and training load are combined so hard sessions land when you're ready. • Race focus — From 5K and 10K to half marathon and marathon: clear mesocycles and peaking strategies toward race day. • Training journal — Your full history in one place. The coach remembers what you've done and what works. THREE LAYERS OF PLANNING 1. Macro — the full season toward your A-race. 2. Meso — four-week blocks with the right load curve. 3. Micro — this week's sessions, adjusted to your calendar and recovery. SYNC YOUR WORKOUTS Connect your Intervals.icu account and your activities sync automatically. The coach analyzes every workout — pace, heart rate, segments, intensity — and gives you feedback the same evening. WHO IS IT FOR? Coach Fartlek is for runners who train consistently, have goals that matter, and want a coach who actually understands both training and real life. Whether you're chasing a sub-3 marathon, your first half marathon, or a faster 10K.
