Joseph Oldendorf broke his leg about 12 miles into a run on a remote trail in the Olympic National Forest in Washington state on Friday at about 5pm 

Oldendorf, whose tibia became detached from his ankle, started crawling on his hands and knees because he had no phone signal to call for help

He got phone signal again after crawling for about seven hours

Oldendorf, who feared he would die if he remained still, continued crawling for several hours until rescuers located him at about 4.30am

Temperatures in the park on Friday night reached lows of 26 degrees
