Liam doesn't care if millions of people all over the world love to do parkrun every Saturday. He would much rather stay home and play games on his iPad. The rest of his family are excited to be part of it all, even his little sister who gets to ride in a pram. She doesn't have to walk or run like Liam does. Liam hates running. It hurts his legs. He mumbles and grumbles, dragging his feet, hanging his head, and complaining the whole time. There were lots of people everywhere, talking and laughing as they made their way around the course… but not Liam. He just doesn't want to be there.
Suddenly, a yellow flash whizzes past him. "BEEP BEEP!"
Liam can't believe his eyes. Can that really be what he thinks it is? He's got to find out!
