"I couldn't walk a mile when I started trying to do this back in January," the "Need a Favor" singer said, adding that he felt "really, really good" about finishing the race. "I left here feeling really motivated."

Jelly Roll announced he had entered the race in January. "I believe in myself," he said in an Instagram video that showed him exercising outdoors, noting that he was "in the woods walking every morning."

By April, Jelly Roll told People that he had lost "70-something pounds" while preparing for the event. "I'm doing two to three miles a day, four to six days a week," he said. "I'm doing 20 to 30 minutes in the sauna, six minutes in a cold plunge every day. I'm eating healthy right now." He added that he was feeling "really good" and planned on losing "another 100, 100-and-something (pounds)."

That same month, he told Variety he had been off of social media for a few months amid bullying as well as the health benefits of taking a social media break.

"I've never felt better or healthier mentally — never felt more clear-headed," he said. "I've also never had less of an idea what was going on in the world, but I tell you what, I'm definitely not coming back before the election."
