Deciding fact and dimension tables

Imagine that you love running and data. It's only natural that you begin collecting data on your weekly running routine. You're most concerned with tracking how long you are running each week. You also record the route and the distances of your runs. You gather this data and put it into one table called Runs with the following schema:

runs
duration_mins - float
week - int
month - varchar(160)
year - int
park_name - varchar(160)
city_name - varchar(160)
distance_km - float
route_name - varchar(160)

After learning about dimensional modeling, you decide to restructure the schema for the database. Runs has been pre-loaded for you.
