The exact distinction between the two can be a bit blurred, but basically:-

A workshop is a hands-on and practical training experience. Sometimes they are residential and span several days and other times they are one-day workshops.

A course is not residential and usually lasts one day. However, we do plan to introduce evening classes that may span several separate evenings.

The individual course page will give details of the time and location of the training, whether it is a workshop or course.
