I don’t know if I should

The college I’m going to has free sports and one of which is cross country which I did in 6th grade (I’m a senior now) but the problem is if it’s in the afternoon (they said it’s 3 days a week) then idk how I could schedule work, since I’m scheduled my classes for in the morning (school starts in August and I’m graduating in May). I was thinking about signing up for the gym, but now I’m presented with this and idkkkk. With the gym I can give whenever I want with cross country idek what days of the week or times they are at. 😩
