No — LeCoach plans your training, not your roads. There's no route builder, no GPX upload, and the coach can't open route links (Strava routes, Komoot tours, race GPX files).
What LeCoach does instead
Describe the course and the coach works with that: 'Sunday's race is 120km with 2,400m climbing, the decisive climb is 8km at 7% starting at km 95' is everything it needs to prep pacing, fueling and the taper. Course profiles of your completed rides are, of course, fully analyzed — with the map shown on the activity.
Good tools for the route side
Komoot, Strava routes and your head unit's own planner all do routes brilliantly — and your device happily runs a route and a LeCoach structured workout side by side on a training day.
Workout distance
LeCoach workouts are time-based (a 2h30 endurance ride, not an 80km one) because time × intensity is what training load is made of. Want to know roughly how far a workout will take you? Ask the coach — it knows your speeds.
