Is LeCoach's 'load' the same as TSS?
Effectively yes. LeCoach uses the training load calculated by Intervals.icu, which follows the same principle as TSS: one hour all-out at threshold ≈ 100 load. Your Garmin or other platforms may show slightly different numbers because each calculates independently — same concept, different implementations.
Fitness (CTL), Fatigue (ATL), Form (TSB)
CTL — fitness: your load averaged with roughly a 42-day horizon. Builds slowly, fades slowly.
ATL — fatigue: the same over roughly 7 days. Spikes quickly after big days.
TSB — form: CTL minus ATL. Negative = carrying fatigue; positive = fresh.
CTL and ATL come from Intervals.icu with your data sync; LeCoach computes form and projects all three forward from your scheduled workouts — that's how it can show your expected fitness and freshness on race day (plan health).
The training status labels
Detraining (form above +25) — too fresh for too long; fitness is draining.
Fresh (+5 to +25, shown blue) — recovered and ready to perform. Where you want to be on race day.
Maintaining (−10 to +5, gray) — holding steady.
Improving (−30 to −10, green) — productive training stress. Where you want to live in build weeks.
Overreaching risk (below −30, red) — more fatigue than most athletes absorb well; back off or discuss with your coach.
So blue is good?
Blue (Fresh) is *good before a race* and *suspicious mid-build* — being fresh for weeks means you're probably under-training. Context is everything, which is why plan health checks your form against the block type you're in.
