Running. It's a thing that humans do. They run. They're good at long-distance endurance, they're not too bad at short distance sprints, and some people run for fun. Like Theo. He's running a 400m dash, he started about 25 seconds ago, and he's about halfway through. That's pretty quick for someone who just started running properly at the beginning of the year. He gets first place. The other runners don't seem thrilled.
