The NASCAR Cup Series makes its annual summertime trip to Pocono Raceway, a track notorious for being the only triangle-shaped raceway of its kind. With three different corners featuring three completely different shapes and degrees of banking -- conjoined by especially long and fast straightaways -- figuring out how to go fast around Pocono has long been a confounding task for drivers and crews alike.

The NASCAR Cup Series continues today, as racers compete in The Great American Getaway 400 this afternoon. Fans can watch this race for free.
