Averaging 45 miles per day and sleeping only four hours per night, Josh Garrett, 30, reportedly broke into sobs as he reached the trailhead in Canada.
"I cried, I broke down and bawled pretty good," Garrett told the San Francisco Chronicle. "My girlfriend (Karen Dawn) was waiting for me at the monument with her arms wide open. What a sight. A long time coming."
Garrett, an avid vegan and an exercise physiology instructor, was completing the hike to raise funds and awareness for animal rights group Mercy for Animals. Not only did Garrett beat the speed record, but it was his second time completing the trip.
"In 2009, I hiked the Pacific Crest Trail and it was the greatest experience in my life, hands down," said Garrett in a video for Mercy for Animals. "I wasn't sure if I wanted to go back out there again, but I thought that if I could make it worthwhile for the animals, I would strongly consider it."
The speed record trip wasn't entirely smooth sailing. According to the Chronicle, Garrett collapsed just 100 miles into the journey.
"I had doubts if I could continue," said Garrett. "It was 100 degrees, I was shooting for 41 miles per day, and I collapsed from heatstroke."
But after just one night out of the wilderness and in a hotel room, Garrett was back on the trail.
"I constantly reminded myself, as painful as it was to do the hike, as miserable as it was at times, it was nothing compared to what animals on factory farms and slaughterhouses go through," Garrett said.
