I have found that 25mi of gravel is equal to 45mi of road. At least thats how it is for me with regards to where/how i ride in terms of energy/effort used.
Riding 90mi of gravel would be like 160mi of road then. No idea if that translates since ive never done either 90mi of gravel or 160mi of road!
an average of 30mi/ride a few times a week is fantastic for staying in good condition...but I would be wary to say that is a good prep for 90mi of gravel followed by 2 more large mileage days.
