"This book provides an overview of triathlons, including their history, the description of each event, an introduction to relays, and a section highlighting recent Olympic triathletes. It explains that a triathlon comprises three sports: swimming, cycling, and running. The text is crafted to be accessible to children, with more challenging vocabulary accompanied by definitions at the bottom of each page. The inclusion of action-packed photos enhances the reader's experience, injecting vitality into the otherwise brief introduction to triathlons. Additionally, the back matter contains valuable resources such as book recommendations, website links, and an index. While acknowledging that the book only scratches the surface of the topic, it serves as an excellent primer for this exhilarating Olympic event, likely sparking enthusiasm among young readers for the upcoming summer Olympics. Its broad appeal makes it a valuable addition to large library collections, suitable for a wide range of ages, and its engaging content would make it great for any Olympic-themed display." -- Children's Literature.
