I have my favorites, including the classics; Without Limits, McFarland, USA, Chariots of Fire, Unbroken, On the Edge, Run Lola Run, Marathon Man… but years ago I saw a very original independent film called St. Ralph about a high school boy who pledges (I won’t give away the plot details, but they’re doozies) to win the Boston Marathon. It was very funny, inspiring, and heart-wrenching, and doesn’t make many running movie lists. That might be the one for me. Not for everybody, and it has some moments not appropriate for kids, but I really loved it.
Chariots of Fire.
