On 10 January 2009, Hal Finney tweeted two words: "Running bitcoin".
Hal was the first person besides Satoshi to run the software, but he was also a keen runner, training to qualify for the Boston Marathon. In May 2009 he had to drop out of the LA Marathon halfway with cramping and twitching in his muscles. That August he was diagnosed with ALS (MND). He never got to finish a marathon.
This Sunday I'm running the New York City Marathon in his memory, 42.2km through all five boroughs. I'm raising money for ALS research and care with Team ALS ONE and ALS Network, home of the Hal Finney ALS Research Fund.
If Hal's work means something to you, I'd be grateful for your support:
