It was! Platt River Half Marathon in Denver, CO. An exhilarating shared run and a wonderful memory.

Today was the 21st and final day of the Running Bitcoin 2025 Challenge. I finished my fourth 21K, this year mostly walking, each step done with Hal foremost in my thoughts. I love you, Hal!

I agree! (This photo of Hal was taken in late 2008, only a few months before he started to show symptoms of ALS.)

Finished my 3rd 21K of #RunningBitcoinChallenge in honor of @halfin! Still time to join me at https://secure.alsnetwork.org/site/TR?fr_id=1510&pg=entry

The #RunningBitcoinChallenge is in full swing! Join us in running or walking 21km in 21 days to support ALS research and honor Hal’s legacy. 🏃‍♂️
