Events can be promoted on the Trailforks maps on trailforks.com. These events show a blue marker on all maps to all users all the time by default, and events will also be highlighted in event lists.
To get your event promoted, you must first use the services of BikeReg through AthleteReg. When creating your event through AthleteReg, you will have an option to sync your event to Trailforks and another option to advertise your event on the Trailforks Map for a fee.
