In his career as an actor, Sean Astin has starred in Goonies, Rudy, and the Lord of the Rings trilogy. He ran cross country in high school and got back into running in 1998 when he ran the LA Marathon, an event he has now completed four times. He came on the show to talk about his acting career, but to also talk about his love of the marathon – he now has completed 10 – and the amazing experience he had running the 2015 Boston Marathon as part of MR8, the group raising awareness and money for the cause championed by the family of Martin Richard, the eight year old who died in the 2013 marathon bombings. Next up for the actor, producer, author, and runner? The Ironman Triathlon World Championship!
