Have you heard of this guy? Garret Christensen (trail name: The Onion) is attempting to yo-yo the CDT this year. That means he'll hike from Mexico to Canada then turn around and hike back to Mexico for a total of roughly 6,200 miles. Team 48 crossed paths with this speedhiker yesterday in Helena National Forest. By 5 p.m., The Onion already had 20 miles under his belt for the day and said he finished his north-bound hike in an impressive 95 days. He was on Day 105 or 106 and heading back to Mexico. So he's hiking about 33 miles a day, plus more miles on re-supply days. You can follow his progress on his blog.
