Keoghan's television career began in earnest when he was only 19 with a presenting gig on the New Zealand children's show "Spot On." Although he was in the running to host "Survivor" before ultimately losing out to Jeff Probst, Keoghan is best known for his Emmy-winning work as the host and producer of another globe-trotting reality program: "The Amazing Race."
Keoghan also penned the book No Opportunity Wasted, which became a Discovery Channel series chronicling his attempts to live each day as if it were his last -- and challenging others to do the same.
A reality competition in the form of a globe-trotting series of challenges, this Emmy-winning show features pairs of ordinary people who travel far and wide in the hopes of bringing home the $1 million grand prize. Each team consists of two people in a pre-existing relationship -- from fraternity brothers to family members to ER doctors -- who must overcome physical and mental obstacles as they pass through a variety of exotic locales.
