FAQ

Frequently asked questions about road bike training

Everything about training zones, FTP, Fitness/Fatigue/Form and AI-powered cycling.

What is FTP in cycling?

FTP (Functional Threshold Power) is the maximum power in watts a cyclist can theoretically sustain for 60 minutes. FTP is the basis for all training zones and load calculations.

Typical values: beginner 150–180 W, recreational 180–250 W, advanced 250–320 W, competitive 320 W+.

What do Fitness, Fatigue and Form mean?

Fitness measures your training capacity over 42 days — as it rises, you get fitter.

Fatigue measures the load of the past 7 days.

Form = Fitness minus Fatigue = how rested you are now. Positive Form on race day means: rested and ready.

What is Zone 2 training in cycling?

Zone 2 is the aerobic base zone at 56–75 % FTP. 80 % of training should happen here — you can still hold a conversation easily.

Zone 2 builds mitochondria, improves fat metabolism and is the foundation for all performance gains.

How is the load of a session measured?

Training load combines duration and intensity into a single number. An easy 1-hour ride ≈ 50 points, a hard 3-hour race ≈ 250 points.

For recreational cyclists: 300–500 load points per week is a solid training volume.

Is WattRun an alternative to TrainingPeaks?

Yes — WattRun offers the most important TrainingPeaks features for free: Fitness/Fatigue/Form tracking, Power Curve, FTP tracking, Strava import and AI training plans.

Plus, WattRun has an AI coach (powered by Claude AI) that gives automatic feedback after every upload — TrainingPeaks doesn't.
