Re: How to reset 10 hour trial campaign progress on XBOX?

Answer for xbox  (*Delete everywhere option) 

Press the Xbox button  to open the guide, and then select My games and apps.

Highlight the game, press the Menu button on your controller, and then select Manage game and add-ons

In the menu on the left of the screen, scroll down to Saved Data, then highlight the saved data for your gamertag on the right and press the A button on your controller.

You'll be prompted to confirm deletion of this game save data:

Delete from console removes the local copy of this save. You can get it from the cloud the next time you play.

*Delete everywhere removes your saved data from this console, the cloud, and all other consoles you play on. 

(*select this option )

Cancel leaves your data intact. 

Answer for PC

for pc version disable cloud saves then go to Documents\Need for Speed(TM) heat\SaveGame and delete save file then you can start fresh
