Discovery Channel has announced that Toughest Race on Earth: Iditarod will premiere on Tuesday, October 14 at 10PM ET/PT.

Iditarod -- which is being produced by Thom Beers' Original Productions, the same production company responsible for Deadliest Catch, Ice Road Truckers and Ax Men -- will follow seven of the mushers and sled dog teams that competed in this year's Iditarod Trail Sled Dog Race.

The annual race, which began in 1973 and follows a route that was originally used as a mail and supply route, begins in Anchorage and ends in Nome.  Ninety-six mushers and teams started this March's race, however only 78 completed the grueling 1,150-mile course across the Alaskan wilderness.

Iditarod's cameras followed four veteran mushers: two-time Iditarod winner and 2007 defending champion Lance Mackey, four-time Iditarod winner Martin Buser, four-time Iditarod winner Jeff King, and three-time Iditarod runner-up DeeDee Jonrowe.  In addition, the six-episode series also followed three less experienced mushers: second-time racer Bruce Linton and rookie racers Rick Holt and Darin Nelson.

Discovery had announced Iditarod's pickup in March.

In addition to Iditarod's premiere, Discovery also announced that Dirty Jobs will return with new fourth-season episodes on Tuesday, October 7 at 9PM ET/PT and Storm Chasers' second season will debut on Sunday, October 19 at 10PM ET/PT.
