My son rode on Zwift on my account and his high heart rate led to a 500 point training load increase. Even after having deleted the activity, training load score still remians above 1,000. Does anyone know a way to refresh Trainig load once an activity has been deleted? I use that metric everyday and it would take days of no activities for it to go back to normal level, Also it throws out all other metrics like training readiness, sleep etc... Can anyone help?
