When you open a seasonal by clicking on its banner, you come to the 'event choice' screen, where the list of events is displayed horizontally along the bottom (usually a series of different tracks). Just above these are a few small icons: to the right is a square with a car in it, which takes you to your garage collection without any filters applied. Second from the right is another car with a list on it. This is the list of 'Typical Opponents'. Left of this is the 'Entry Requirements' icon which tells you which restrictions apply and offers to take you to your garage with the relevant filters applied and lastly, to the very left, if applicable, is a box with a bow on it, called 'Prize', which describes the prizes awarded for this challenge. Here is the answer to your question.
