An ultracommuter is someone who travels a really long distance to work every day. It's like when you take a really long car ride or airplane trip, except you do it every day to go to work.
There are different types of ultracommuters. Some people might drive for hours to get to work, while others might take a combination of trains, buses, or bike to get there.
Being an ultracommuter can be tough because it can take up a lot of time in your day. You might have to wake up really early or come home really late, and you don't get as much free time to do fun things or spend time with your family and friends.
But some people do it because they really love their job or because they want to live in a certain place. And they find ways to make the long commute more enjoyable, like listening to music, reading, or catching up on their favorite TV shows.
