How do you earn EXP points

I'm sorry if its obvious but I've been playing for a little while and i haven't unlocked anything and i don't know if i'm doing anything wrong or where to look at exp points i've earned

finish races,i select always a team where rider is suited for wining general clasification and you get double exp
i quick sim every stage except one stage where i can win general clasification
take froome for tdf and quick sim everything except last montain stage
play it on amateur,you make 1000exp super fast to unlock legend dificulty,2 hours takes
