Yes, increasing your weekly mileage. Running longer and slower. Everyone needs a base before anything else.
Can't build a house without a foundation.
I say the same thing as BMX. Work on building a good foundation. The cross country season is too short for your coach to allow for much of that kind of work, and he/she will put you almost immediately into speed work type routines. Having a base first allows your body to respond to that type of training better.
