Marcus Lee

Marcus Lee has hiked more than 8,000 trail miles across three continents, from day loops close to home to multi-week traverses that needed resupply boxes and a lot of planning. He has made most of the common mistakes at least once, which is why his guides spend so much time on the boring parts that actually keep a trip on track.

At KnowOutdoor he writes and edits the activity and planning guides: how to train for a day hike, how to fit a backpack, and how to size your water for the day ahead. He writes for the reader who wants a clear answer and a reason behind it, not a wall of options.

His rule for a guide is simple: it should tell you what to do, why, and what changes the answer. When a topic touches real safety, he hands it to our reviewer rather than trusting his own experience alone. You can see the full team on the experts page.
