ELI5: Explain Like I'm 5

Ultramarathon

Okay kiddo, so you know how running races are when you run a certain distance, like in a school race you might run around a track or a baseball field once or twice?

Well, an ultramarathon is like a super long running race, where people run WAY farther than that. Instead of running just a mile or two, ultramarathon runners might run 50 miles or even more!

It's really tough, and takes a lot of training to get ready for because it can take many hours or even days to complete the race.

But the people who do it feel really proud of themselves and it can be a really fun way to push yourself and see what you're capable of.
