Am I prepared for cross country?

I've ran track since 7th grade (I now will be a sophmore in highschool). I've always been more of a sprinter/short distance guy. I usually run 2-3.5 miles 3/4 times a week on my neighberhood nature trail. Each loop is equal to about 1.5/2 laps of a regular track. It is very hilly and windy (Just like most cross country trails are). I have asthma and practice starts in July so I'me trying to strengthen my lungs. Will I be ready for this season? 2/3.5 miles is my easy range and if I was forced (say by coach/ other teamates) I could prolly run up to 4.5/5.
