CBS in a different kind of doo-doo now.

Besides Rathergate, I mean.

LOS ANGELES (Reuters) -

An Australian has died during a 400-mile race in the northwestern U.S. being filmed by CBS for a sports program, organizers said on Friday.

Australian Nigel Aylott, 38, was killed in a rockslide on Helena Peak in Washington state on Wednesday while he and his three teammates were leading the Subaru Primal Quest, race spokesman Gordon Wright said.

"He was hit in the head by a very large boulder and suffered very serious head injuries. He was killed instantly."

The race, involving running, mountain biking and kayaking, was halted after Aylott's death but resumed on Thursday at the urging of his friends and family.

Some 24 hours later, a second team used emergency beacons to summon help from the same peak. Wright said they had become lost or stranded but walked out of the mountains four to five hours later, before search teams could find them.
