In this exciting sequel to "Mud Run," Matt and his teammates are disappointed when their favourite track coach, Ms. Wellesley, tells them she can no longer lead the school team. On the bright side, she has arranged for the kids to be trained by the coach of the Riders -- a dream team of elite athletes who have the potential to become "real" runners. But is there such a thing as too much, too soon? "Mud Happens" is about learning how to pace one's self -- in the race and in life.
