Gravel Club
Ride together, all levels welcome.
Treeline helps adventurous adults find people they genuinely want to spend time with - and gives them more reasons to go do things together.
Treeline is built around a simple idea:
The right people + the right experience = the beginning of a real connection.
We learn what you like, how you like to adventure, what you're curious about, and what kind of people you naturally click with. Then we create opportunities for those people to meet in the real world.
Not another social network.
Not another group chat.
Not another place to collect acquaintances.
A better way to find people you actually want to go somewhere with.
The heart of Treeline is our people. Every week, we gather for runs, rides, hikes, and community nights—not to compete, but to share the joy of moving outdoors, together.
Here, no one is left behind. You'll always find someone waiting at the finish line—ready to cheer, to share snacks, and to plan the next adventure.
Treeline was built on the belief that the outdoors are better together. Rooted in New Hampshire, we're a place where trails turn into stories, shared meals, and friendships that last long after the hike. Stop in for our next gravel ride or group run, a taproom full of good conversation, and a community that makes every adventure feel like coming home.
Our Portsmouth clubhouse is where explorers meet after the trail. Cold drinks, warm people, and plenty of plans for the next outing.

Good people, a little adventure, and a community worth showing up for.
