Coeur d'alene training location

Hello, I am heading to Lake Coeur d’alene for a wedding and will be there for 3 days. Any suggestions on good swimming/running areas? I will not be taking my bike. Thanks

You can run along the centennial trail - the IM run course. It is car-free and right along the lake. Open water swimming is right there on the beach. If you are staying at the resort, they have a lap pool as well.
