Pastrana, who has captured an astounding 17 medals at the X Games, including 11 gold medals, wasn't able to beat out Heikkinen, Tanner Foust, Sverre Isachsen and Rhys Millen when all was said and done on Sunday in Irwindale, finishing a distant fifth with a time of 6:47.646.
The 29-year-old will always be revered in the extreme sports world, no matter what he does from here on out, but he's had some hard times recently as he has attempted to race in NASCAR. In July, he gave himself a "C+" in his first full season in NASCAR, per Yahoo! Sports.
Overall, Pastrana can't complain, of course. Winning gold freestyle motocross as a 15-year-old in 1999 started off his career with a bang. He went on to win gold in the X Games in 2000, 2001, 2003, 2005, 2006, 2008 and 2010. And who can forget his double backflip in 2006?
Were you surprised by Travis Pastrana's finish?
But Sunday's result certainly wasn't what Pastrana was hoping for. Before his official finish, Pastrana finished second in his qualifying heat.
Pastrana said after his qualifying heat, via ESPN.com: "The team has been doing a great job on the car, but we were way off in practice. We're making changes, we're making improvements."
It didn't help that Pastrana was racing against Heikkinen, who won for the fourth straight time on the Global Rallycross Championship and captured his second X Games gold in a row.
It would have been nice to see Pastrana at least medal in the final X Games based in Los Angeles, but he wasn't able to do enough on Sunday to make that the case. He will move on, whether it be in NASCAR or other racing opportunities, seeking more accolades to add to his already impressive resume.
