During a Twitch stream on March 10, 2025, popular content creator Roberto “Fanum”shared a concerning incident in which he suffered a concussion while participating in MrBeast’s latest challenge, dubbed the “largest treadmill on Earth.”This event took place on March 7, during a practice session for the Sidemen Charity Match, where Fanum was among several influencers contending for the title of last man standing.
As part of the challenge, Fanum experienced a significant mishap when he lost his balance and struck his head against the treadmill. He first revealed his injuries in Snapchat posts made on March 8, and during his Twitch broadcast, he disclosed the severity of his condition, expressing the level of discomfort he felt following the impact.
“Can you believe that that bounce right there, literally gave me a concussion? Saying cap? Alright bet. Look, I slapped the treadmill with the side of my head. Bro, it felt like I was in a fight, right? Like somebody had just rocked me, boom! It hurt instantly.”
Fanum proceeded to describe the aftermath of the incident. After returning to his hotel room, he began to feel severely dizzy and ultimately experienced vomiting, symptoms he related directly to the fall:
“Then I was deada** dizzy, I’m like, ‘Damn, I’m feeling dizzy bro, why am I feeling dizzy, bro.’ Then I was like, ‘Whatever. Let me just walk it off, right? I’m not going to make too much of it.’ So I get to my hotel room, and I deada** started throwing up, chat, no bullsh*t.”
Google Searches and Health Fears After the Treadmill Incident
In a frantic attempt to understand his symptoms, Fanum recounted how he turned to Google for answers, which only escalated his concerns about his health:
“Started googling sh*t, like yo I hit my head and I’m throwing up, what’s going on? Ni**as started saying I have CTE, ni**as telling me I have Alzheimer’s. You start googling sh*t when that happens bro, you start feeling like your life is over. I was like, ‘Damn, it’s over. I’m cooked, I’m cooked.'”
Ultimately, Fanum’s situation was not as dire as he initially feared. After consulting a medic, he received a course of ibuprofen and other pain medications:
“Long story short, I had a medic come look at me real quick, pop a couple of pills like ibuprofen and other type of pills and sh*t. But it’s because my dumba** tried to exercise, and that’s why I shouldn’t exercise, chat.”
Fanum humorously concluded his tale by reiterating the importance of moderating his physical activity to prevent similar occurrences in the future:
“And that’s why I keep telling people I need to exercise a little less because of sh*t like this. You know what I’m saying?”
Interestingly, Fanum was not the only participant to face challenges during MrBeast’s treadmill event, as many other content creators also experienced falls, while one well-known YouTuber emerged as the winner after narrowly avoiding elimination.
