Earn as many fame points as you can for this. To gain fame points you need to complete challenges. It may take a little while to get 186, but once you start to complete a few challenges you will be offered a sponsor challenge every 50 fame points earned. Beating sponsor challenges and media challenges will give you 5+ points each time. If you already have a sponsor, complete the new sponsor challenges and if asked if you want to replace your current sponsor, reject the offer. Doing this will give you 20 fame points every time.
Just keep completing media challenges. If you want to check your progress, access your phone by pressing
while on a mountain or on a drop point selection screen and you can find your fame points at the bottom of the phone screen.
