Contributor Lauren Groh has been through-hiking the Appalachian Trail this spring and summer. So far, she and her hiking companions have hit several major milestones - including reaching 400 miles on the journey.
Groh checked in from the trail just recently and reflected on the day-to-day challenges of surviving such a major undertaking:
It's day 42 in the Appalachian Trail. We left Erwin, Tennessee three days ago, and our next stop is Hampton. We will hit the 400-mile mark tomorrow, if we push it!
