Operation Jack Northwest Run
In 2010, Sam Felsenfeld set out to run marathons as way to raise awareness and money for autism research in the name of his son Jack (who is severely autistic). Sam ran 61 marathons and raised about $100,000 for Train 4 Autism (an organization that helps raise money for various autism organizations). The final race of that year was on December 26 in Southern California. His supporters in the Pacific Northwest held an event on the same day which was a 6.1 hour run (in honor of Sam's 61 marathons). It's called the Operation Jack Northwest Run.
