Ben knows he's taking on a lot, offering to do the first hundred lengths of the swimathon himself, but he's desperate to impress Jack and Harry. But as he swims - and swims - Jack realises that his 'friends' aren't going to show. Now he either has to forfeit or swim another hundred lengths! But support and encouragement come from an unlikely quarter and Ben pushes his way to victory. Particularly suitable for struggling, reluctant and dyslexic readers aged 7+
