Sean Englund
founder
Sean Englund began slacklining and highlining in Durango, Colorado over a decade ago.
Since then, his love of the sport has only grown. What began as a hobby quickly turned into a lifestyle and career that would take him across the world in pursuit of certifications, mentorship, world record-length lines, and highlining competitions.
Sean holds certifications at the international level for slacklining and highlining, as well as nationally-recognized certifications in Paragliding and Avalanche safety. He is an avid outdoorsman and focuses on safety at every turn. When considering who to go into the outdoors with, he is a professional who knows how to handle extreme projects, and is an easy choice to go with.
Sean always dreamed of creating his own highline-focused company. When he found himself with extra time in the fall of 2023, maybe due in part to a lengthy speed-flying crash recovery, the dream finally began to take shape...
Uncharted Lines was born.
From the very beginning, Uncharted Lines has been involved in the Durango community and has aimed to serve people of all ages and backgrounds. Many outdoor sports have a high barrier to entry through cost and access, and Sean seeks to break down those barriers for everyone by bringing slacklining and highlining directly to the people through Uncharted Lines.
By providing the materials, mentorship, and excitement he has already made a huge impact with nonprofits and youth groups in the area... and there is so much more to come.
Sean believes the mental, physical, and social benefits of participating in these activities are like no other and plans to share that knowledge with outdoor enthusiasts near and far.

---These goals are at the heart of what guides Uncharted Lines---
“ Highlining reminds me to push the limits of what I believe is possible... and I think everyone should experience that ”
-Sean Englund
Why go outside with
Uncharted Lines?
Sean has watched the evolution of slackline and highline history and has taken an active role in pushing the limits of this sport. He was there in the beginning when lines were “double tensioned” and the lengths of 200+ meters seemed like an impossible distance. Now, he has seen the gear, sport, and communities come a long way.
He has proved his exceptional devotion and skill within the sport by participating in world-record length highlines, serving on the board of education for the International Slackline Association, and maintaining sponsorship with Balance Community: Slackline Outfitters, a top creator of highline gear and webbing. He finds quiet in the simple, though intense, action of walking across a small strip of webbing suspended in air and has never met a stranger.
When trying a new activity, or pushing yourself further in a known one, you should always go with someone you trust rather than a “DIY-er”. Certifications mean something in the outdoor world and he’s the one running the courses for them! Community, safety, and dreaming big are his priorities and he will always be excited to share these sports with you in any capacity.
Whatever your background, history, goals, or ability levels... you deserve to be here!
Uncharted Lines is so excited to meet you and work with you.
Cheers,
Sean & Blueberry
