So…what mode do you have it on for rides and races?
Erg mode is only applicable to workouts. To get into erg mode for group rides or races you’d have to be start a workout and then join the event. Or, I suppose, vice-versa. I’m not sure the software would even allow that, but certainly there’s no reason I can think of that you’d want to do so. Group rides and races are all about reacting to events and riding in the moment. Erg mode is, in a sense, designed for exactly the opposite.
Errrrrrrrrrg, … I rather think it should be off, … why would you want to be in ERG?
