Events in Forza Horizon 3 span across all four main sites of the Horizon Festival Australia, the King of the Mountain tournament at the Blizzard Mountain site, and the Hot Wheels Campaign at the Horizon Hot Wheels site.
Routes for events are identified by festival scouts as players earn fans towards the Horizon Festival. New routes are unlocked as new festival sites are opened and existing sites are expanded upon with higher site levels.
There are multiple routes associated with the Horizon Festival, with each being tailored towards specific driving terrain types such as asphalt, off-road, and cross country.
Each regular festival route location offers three event types;
Exhibition - A single event in Australia made up of only that route.
King of the Mountain - A single event on Blizzard Mountain made up of only that route with three objectives.
Hot Wheels Campaign - A single event on Horizon Hot Wheels made up of only that route with three objectives.
Championship - An event made up of multiple routes with that route being a possible first stage.
Rivals - Compete against lap times set by other players for that route.
Circuit routes take place along enclosed roads and can have multiple laps.
