* API Users can create an account and log in.
* All API calls are authenticated using a form of OAuth.
* There are three roles with different permission levels:
** a regular user can CRUD on their owned records,
** a user manager can CRUD only users,
** and an admin can CRUD all records and users.
* Based on the provided date and location, the API will connect to an external weather API provider and get the weather conditions for the run, and store that with each run.
* A report endpoint exists that aggregates average speed & distance per week.
* Filtering capabilities exist for all endpoints that return a list of elements.
** Parenthesis are used for defining operations precedence and on any combination of the available fields.
** The supported operations are or, and, eq (equals), ne (not equals), gt (greater than), lt (lower than).
* Pagination exists for all endpoints that return a list of elements.
* Testing was done with unit tests and integration tests.

The project was built using a Java Spring Boot back-end, a MySQL database, and docker to spin up the modules.
Integration tests written in Ruby.
