Mary Wittenberg and Richard Branson of Virgin Sport

Billionaire Sir Richard Branson is best-known for his multiple Virgin-branded businesses and media-friendly attitude, sharing stories of freezing his sperm, pictures of his vacation with the Obamas and a poem for entrepreneurs on his blog over the past month.

He's also known for his sporting challenges – from his world record-setting Atlantic hot air balloon crossing in 1987 to the Virgin Strive series of triathlons in Italy last September. So it's fitting that his latest venture is Virgin Sport, festival-style events that will take place in the U.K. and U.S. this year.
