Phil Keoghan will again serve as host of "Race," the Emmy Award-winning, race-around-the-world show's 19th season.

Keoghan has been part of the series since it began.

"Boss" follows high-level corporate executives as they pose as lower-level employees in their own companies.

It debuted last year and just wrapped its second season.
