OP here: Thanks for the suggestions!

Agree with above - swim, dance, gymnastics, basketball are all good options.

My daughter does swim dance and gymnastics

Basketball is also a winter option

We are in VA and DD and her friends started rec basketball in kindergarten. I don’t know much about MD but a quick search came up with this https://montgomerycountymd.gov/rec/Resources/Files/activitiesandprograms/sports/basketball/YouthBasketballBrochure.pdf

Any ideas for winter sports for a kindergartner (girl) who is super competitive? Soccer this fall was great and we are looking for something else to keep busy over the winter. We are in Mont. Co. but would consider upper NW as well due to commutes.
