According to Bertram van Munster, co-creator and executive producer of The Amazing Race the, viewers may need a seat belt when they watch this season, which begins Sunday night.

He told Reality TV World the competition will be kicking the danger level up a few notches during this fall's thirteenth edition.

"[This season] you will see a tricky one where you will wonder 'How in the world did they have the guts to do this?' You are really going to wonder," van Munster said. "I look[ed] at it and I [went] 'Oh what was I thinking? Oh my god, this could go very wrong.'  And then it does."

Overall, the goal was to increase the pressure and the challenges facing contenders.

"What I've done [for this season is] I've come up with so many insane challenges that it should do the trick and I think it will be plenty exciting for an audience to watch it," the producer added.
