Jillian Bailey (nickname Jellybaby) has never really been the sporty type. So when it comes to a choice between the school sports day or the school marathon, Jillian settles on the marathon as the lesser of two evils, and she starts training with her new neighbour. Her Aunt Rilla and her best friend Zena think she's mad, but Jillian's on a mission to achieve what she thought was impossible. Suggested level: primary, intermediate.
