Need advice for a swimmer - what sport to add or transition to from swimming?

We have boy’s WP in the fall, Girl’s WP in the winter and B/G Swim in the spring.

Athletes can enroll in 6th period aquatics for the entire year even if they only do WP or swim. They are not forced to compete in both.

My freshman ran xc in the fall and is now swimming. She had no winter sport and alternated running and swimming in her off season.
