Sarah Greyson was born on Dec. 10 in 1983 in the small town of Edmond, Oklahoma. Sarah is the child of two wealthy doctors. She is Italian and it turns out that her grandmother is a descendant of Phillip Mazzei, who helped finance the American Revolution and signed the Constitution of the United States.
She is best known for her appearance on MTV's Road Rules 11 Campus Crawl. She was on the show for 11 out of 17 episodes. She did not do that great on this season. A little out of shape would be a compliment. She then appeared on MTV’s Real World/Road Rules Challenge: The Gauntlet, where she did much better. After dropping 25 lbs, she competed extremely well. Although a few fellow cast mates from the same Road Rules 11 doubted her and repeatedly sent her into the Gauntlet. Sarah eventually proved victorious, and aided the Road Rules team to win in the final challenge.
