UMass Amherst has a decent art program, and XC, indoor and outdoor track. I ran there in the 70s. Had a positive experience with both academics and running. One warning, sooner or later you will take long afternoon studio classes and will miss workouts.
This being the case, I chose not to compete as a senior.
On the other hand, my nephew went to Pratt, the art school in Brooklyn. I don't know how it is academically, but the connections he made there led to illustration gigs in the NY Times and the New Yorker, as well as plenty of work at Cartoon Network and Disney. Pratt does not have athletics.
