If you're on Nostr, you already understand why owning your data matters. You've left platforms that exploit your content, mine your social graph, and lock you into their ecosystem. So why would you accept anything less from a fitness app?
RUNSTR is the fitness app built for Nostr from the ground up. When you log a run, a bike ride, or a strength session, it doesn't get stored in our database. It gets posted to your relays as a kind 1301 event - just like a note, but for workouts. Your fitness data lives where your other Nostr content lives: under your control, on relays you choose, signed by your keys.
There is no RUNSTR database. There is no account to create. You log in with Nostr, and your workout history is whatever your relays have stored. Switch apps tomorrow? Your data comes with you. That's the point.
What RUNSTR Does
Track Everything - Running, walking, cycling, hiking, strength training, yoga, meditation. Log workouts manually or sync from your existing wearables (Garmin, Fitbit, Strava imports coming). Every workout becomes a kind 1301 note on Nostr.
Nostr Health Sync - We built something we call Nostr Health Sync. Think of it as an open-source version of Apple Health or Android Health Connect, but decentralized. Health and fitness data aggregated from Nostr itself, not a proprietary silo.
Find Events and Clubs - RUNSTR.Club is our companion website where you can discover fitness events and running clubs. No platform fees. Events broadcast to Nostr, so they're discoverable across Primal, Damus, or any other client.
What's Coming: RUNSTR Premium
We're launching RUNSTR Premium - a membership that actually pays you to stay active.
For 100,000 sats per year, you get:
-
Weekly Bitcoin rewards based on how often you work out
-
Access to RUNSTR Seasons - our exclusive virtual competitions
-
Discounts to in-person RUNSTR events
The reward math is simple: work out 2 days a week and you break even on your membership. Work out 3+ days and you profit. At 6-7 days per week, you're earning 30% more than you paid - and that's denominated in sats, so any Bitcoin appreciation is pure upside.
We're finalizing the payout infrastructure now. Premium is coming soon.
RUNSTR Season 2: Run for Charity
Starting January 1, 2026, we're launching Season 2 - a two-month fitness competition with a 1,000,000 sat prize pool.
Here's the twist: the prize money goes to Bitcoin charities, not individual athletes.
When you log a workout, your distance contributes to your chosen charity's total. Support OpenSats? Every kilometer you run adds to OpenSats' running total. At the end of the season, the charity with the most cumulative distance in each category (running, walking, cycling) wins that category's share of the prize pool.
You're not just getting fit - you're directing real Bitcoin to causes that matter. Top performers get medals. Premium members earn their weekly sats throughout. Everyone moves the needle for their charity.
Why We Built This
Fitness apps have the same problem social media had: they harvest your data, lock you into their platform, and give you nothing in return except gamified badges that mean nothing.
RUNSTR flips that model:
-
Your data stays yours - kind 1301 events on your relays
-
No platform lock-in - Nostr is the database
-
Real rewards - actual Bitcoin, not points
-
Community events - in-person races that fund the whole ecosystem
We're building the fitness platform Nostr deserves.
