Running bitcoin

[halfin @halfin]

Hi Bitcoiners – it’s Fran again.
17 years ago today, Hal Finney posted two words that changed everything: “Running bitcoin.”
Since then, thousands of bitcoiners across 50+ countries have run in his name.
The 5th #RunningBitcoinChallenge starts NOW. ⚡️🏃‍♂️
Are you in? 👉 https://t.co/CvI3MyRx9G
Hal believed code could set humanity free.
He was an avid runner, until progression of his ALS made it impossible.
The 2026 Running Bitcoin Challenge runs for 21 days starting today, the anniversary of his legendary tweet. 🌍
Run or walk 21 km / 13.1 mi– every step contributes to ALS research. 📷https://t.co/CvI3MyRx9G
This year’s challenge is backed by giants:
⚡️ @HRF – defending human freedom with Bitcoin
⚡️ @blocks – @jack’s company building on open money for the world
Hal would be grateful and proud of your support. Thank you!
We are also being supported by @strike - thank you!
I’m also proud to highlight HRF’s Finney Freedom Prize, honoring work at the intersection of Bitcoin, freedom, and privacy.
Congratulations to the 3rd halving era’s winner, Andreas M. Antonopoulos - who educated millions on Bitcoin and its potential for humanity.
Hal would be proud of your work. 🏆
I’m Fran Finney (@franfinney), Hal’s wife.
Every January, I watch this community show up – running, walking, donating, sharing.
You keep Hal’s spirit alive. That means everything. 💛
Find me on Nostr: 🔑 npub14fkfcx9j0494g8zejfdxsr9t8raxt9n8vzkz6l5w4ef0gjysh4dqcsmkgv
Where does your donation go?
✅ 80%+ goes DIRECTLY to ALS research
✅ They accept Bitcoin
Every sat, every step, every share → closer to a cure.

21 days. 21 km. 1 legend.
The 5th #RunningBitcoinChallenge is LIVE.
Run. Walk. Donate. Share.

Hal ran toward the future even when his body wouldn’t let him.
Join us in honoring him – and feel free to share a picture from your run.
