Coach Fartlek — your personal AI running coach
Coach Fartlek is a proactive AI running coach built for serious recreational runners. The coach gets to know you, plans your training, and reaches out when it matters — 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 — Builds you toward your races with clear mesocycles and peaking strategies.
• 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 or just want to be a stronger runner this season.
