Philip Werner is a full-time outdoor author and backpacker who resides in New England. His website SectionHiker.com is ranked as the #1 Hiking and Backpacking Blog on the internet by AdventureJunkies.com in 2018, 2019, 2020, and 2021.

The name of this site, Section Hiker, refers to the Long Trail which I section hiked in 2008 and the Applachian Trail that I’m still working through. To date, I’ve completed 1400 miles of the AT and hope to complete all of the sections between Georgia and Maine someday. I’ve also hiked thru-hiked the TGO Challenge (Coast-to-Coast across Scotland) twice and I’m currently section hiking the Cape Wrath Trail, also in Scotland.
