Their miles.
Everyone's mountain.

Fitness apps made everything a solo leaderboard.

You ran 5 miles. Cool. You're #47 in your city. That's supposed to motivate you? The thing that actually keeps people moving is belonging to something bigger than their own stats.

Individual rankings kill motivation

Most people will never be #1. So they stop trying.

Group challenges are capped and shallow

Strava limits groups to 24. No collective goals. No shared milestones.

No accountability on submissions

Anyone can claim anything. No peer review. No credibility.

How it works

Three moves. One mission.

01

Create your community

Running club, climbing crew, CrossFit box, hiking group. Any community can set up and invite members in seconds.

02

Set a collective goal

Run 100,000 miles. Climb 100 mountains. Log 10,000 workouts. Your community picks the mission. Everyone contributes.

03

Stack activities together

Submit real-world activities. Peers verify them. Every contribution moves the group closer. Watch the bar fill up together.

The difference is whose progress you're watching.

Community-created challenges

Your group defines the goal, the rules, and the timeline. Not the platform.

Peer-moderated submissions

Members and admins verify activity submissions. Credibility without central control.

Collective milestones over leaderboards

The dopamine hit is when YOUR community crosses 50,000 miles, not when you beat a stranger.

Activity-agnostic

Runs, hikes, climbs, swims, yoga sessions, gym workouts. If your community does it, MileStack tracks it.

Example communities

Goal: 100,000 miles in 2026

The Cliffs Climbing Crew

Goal: Summit 500 routes this quarter
Every send counts. Peer-verified by climbing partners.

Sunrise Yoga Studio

Goal: 5,000 hours of practice

The best motivation isn't beating someone. It's building something together.

MileStack is for communities that believe individual effort means more when it counts toward something shared. Every mile stacked is a mile closer to a goal nobody could reach alone.
