Los Angeles rapper Murs is currently attempting to rap for 24 hours straight in an attempt to break the world record for longest recorded rap session. There’s no Guinness World Record for the achievement, but he has to complete at least 24 hours to qualify.

The rap marathon is currently underway which you can watch in the video above. Murs does get five minutes every hour for a bathroom break. Other than that, he has to keep rapping.
