I’ve found that entering gravel races as either “Climbing Road Race” or “Rolling Road Race” gives me a better training plan. Wen I just enter a gravel race as an “A” event I get the Gran Fondo specialty plan, which has a lot less V02 max and anaerobic work. I use “Rolling Road Race” for all my gravel events because the specialty phase mimics the efforts to be in the lead group at my events with shorter punchy climbs. You’ll probably get the same base and possibly build phase for either event type.
I also favor a higher cadence and ignore most of those drill. I add my own low cadence work into threshold, SS, and endurance workouts to help break up the long intervals.
