While running the last mile of a youth triathlon Sunday, Ben Baltz's prosthetic leg broke and the 11-year-old went down. That's when a group of Marines stepped in and carried him the rest of the way.

More than a few people crying as they crossed the finish line.

According to the CNN iReport, Ben completed the 150-yard swim and 4-mile bike ride and half the one-mile run when a screw came loose and his running leg broke in half.

His mother said, "Everybody was crying…cheering and giving them support."
