Tim Tebow isn't the only famous athlete saving his virginity for marriage, track and field star Lolo Jones is as well. In a recent interview for HBO's Real Sports, the runner talks about her struggles in the dating world. Jones says of her ongoing quest, "This journey has been hard. It's the hardest thing I've ever done in my life. Harder than training for the Olympics. Harder than studying for college has been staying a virgin before marriage."
