What happens when a ride arrives
WattPlan reads the file and works out Weighted Power, Intensity, Load and time in each zone. If there is no power, it works Load out from heart rate, and with neither, from how hard you say the ride was. It then updates Fitness, Fatigue and Form, checks nine power durations from 5 seconds to an hour for a personal best, and compares the day's Load with what the plan asked for.
Load
Load measures the training stress of a ride. An hour at your FTP is 100. The dashboard shows today's Load against the plan; go well over target and the Coach will suggest a lighter day or a rebalance.
How hard was it?
After a workout in the app, WattPlan asks how hard it was: Easy, Steady, Hard, Very hard or All out. For a ride from Garmin, Strava or Wahoo, answer on the ride's page or on Today. It takes one tap, and the Coach reads it alongside the numbers.
For a ride with no power and no heart rate, your answer gives it its Load. A session from your plan counts its planned Load for the time you rode, moved when it felt clearly harder or easier than it should; any other ride counts by the hour, and an hour that felt Hard is about 70. The ride's page shows where its Load came from.
FTP
WattPlan estimates FTP from your best efforts and asks you to confirm before it changes anything. It never rewrites your zones silently. Set FTP yourself in Settings whenever you have a better number.
Editing a ride
Open the ride and tap Edit to correct Load or duration, for example after a power meter dropped out. Edited rides are marked so you can see what changed, and a Load you type in stays as it is: nothing works it out again later.
Long rides
Very long rides are thinned before storage so the file fits; charts still draw the whole ride. GPS is kept unless the ride is exceptionally long.
Deleting a ride
Delete from the ride's page. Fitness and Fatigue recalculate on the next import; the ride is not removed from the platform it came from.
