Running 26.2 miles is hard enough, but could you run 26.2 miles while juggling the entire time?
That's what jogglers do. Joggling (jogging and juggling) is a real sport that a bunch of real people compete in.
Here's the rules:
1. You must juggle at least three balls constantly.
2. If a ball drops, the runner must return to the drop-spot and resume the race from there.
From there, people can get creative, using more than three balls, or clubs, or even knives (though that is discouraged). But most jogglers just use beanbags stuffed with bird seed.
