A serial Guinness World Record holder has officially added another title to his list after completing a marathon while wearing 125 T-shirts, according to UPI Odd News.
David Rush took on the challenge at the 2026 YMCA Famous Idaho Potato Marathon on May 16, finishing the race in 5 hours, 54 minutes and 50 seconds. That left him just five minutes under the Guinness World Records cutoff time of 6 hours.
Rush had previously set the half-marathon version of the record with 137 shirts at the 2025 Famous Idaho Potato Half Marathon. He said he spent months preparing for the marathon attempt by training with heavy weights and extra layers of clothing.
During the race, Rush said he began to overheat and ran out of ice, forcing him to stop at a golf course along the route. Guinness World Records has since confirmed that he broke the previous record of 100 T-shirts.
