Upload Garmin/bike computer FIT files to calibrate the model to your actual training history

How to use: Pick a block length, enter planned weekly TSS, and hit "Run Simulation." Use the taper tool to model peaking for a target event. Or upload your FIT files above to calibrate the model to your actual training data.

1. Block length

2. Choose a scenario

3. Set weekly TSS

Blue-highlighted weeks are recovery weeks. Edit any value directly.

4. Add a taper? (optional)

Fitness & Fatigue Balance

Form (Freshness) by Week

Training Stress Balance = Fitness − Fatigue. Positive = fresh. Negative = fatigued.

Optimal Taper Finder

Searches every possible taper start, type, and depth to find the combination that produces the highest peak power.
