Murs is going to test his hip-hop endurance like never before this week. The rapper will attempt to break the Guinness World Record title for longest rap marathon at 24 hours during the season finale of Boost Mobile's Where You At? LA event, brought to you by Boost’s Unlimited Music Streaming featuring Slacker Radio.

On Oct. 12, Murs, who serves as the host of Where You At? LA, will attempt to rap consecutively for more than 24 hours straight.

"For the season finale of Where You At? LA, we wanted to do something a little bit outrageous. Once I volunteered to break the record for rapping and my team loved the idea, my heart kind of sunk a little. Doing anything for more than 24 hours straight is insane, but to rap lyrics live for that long in front of the world is a huge task for me. Wish me luck!" Murs says.

To prepare for this record-breaking feat, Murs has been working closely with his friend and producer, Mr. Len, to find songs that he knows best and edit them down for continuity considering he has to keep rapping -- with only one 5-minute break per hour. He's also been streaming six-hour rehearsal sessions on his Twitch channel.

In a recent Instagram video Murs gave his followers a peek into his training regimen, which includes a healthy vegetarian diet of fruits and vegetables, while practicing his rhymes.

This main event is the conclusion of four prior Where You At? LA shows featuring interviews and performances with the likes of Dame Dash, YG, Casey Veggies, Tha Dogg Pound, Chef Roy Choi, B-Real, DJ Quik, W.C., Mike G of Odd Future, Problem and J-Boog.
