Tell us about your hike
Gear, pacing, rest days and how it ended. Don't remember a number? "Don't know" is a perfectly good answer.

The trail has stories.
We're about to count them.
Why do some hikers finish and others go home early? What actually causes injuries? There is surprisingly little data to be found! Open Trail Science is survey for long-distance hikers, and every answer goes into a free and open dataset for everyone.

What's coming
Ten minutes for you, years of answers for everyone
See how you compare
Right after you submit: how your pack weight, pace and zero days stack up against other hikers on your trail, with a card you can share.
Help future hikers
Your anonymous answers join a free, open dataset anyone can download, from first-timers planning a trail to researchers studying injuries.
Didn't finish?
Your hike matters just as much. Maybe more.
The hikes that stopped early, because of an injury, money, burnout, weather or life back home, are the ones that explain why hikes end. Section hikers and flip-floppers count too. Keep your story ready.
Every hike counts
