December 3, 2025
If you’ve ever wondered how to layer while running, Idaho’s David Rush is your guy. On May 17 in Boise, Idaho, Rush bundled up into 137 T-shirts and completed the Famous Idaho Potato Marathon half-marathon in 2:51:44, which, as of last week, became a new Guinness World Record for the most T-shirts worn during a half-marathon. (Runners must complete the distance in less than three hours).
Rush had previously earned the record after running the Famous Idaho Potato half-marathon in 2019, wearing 111 T-shirts. The record was later taken by another runner, who donned 127 T-shirts.
