It was only a few months ago when we reported that the Guinness record for most T-shirts worn during a half marathon was broken by David Eliuk of Edmonton, Canada. But if there’s one thing that’s for certain, it’s that records are made to be broken.

In this case, it was a quick one to fall when David Rush of Idaho broke the record earlier this month during the YMCA Famous Idaho Potato Marathon at Lucky Peak State Park Sandy Point. It was astounding enough to read that Eliuk donned a total of 90 T-shirts in his record-setting race, and with a respectable time of 2:37:54. But Rush topped that with his impressive effort and now holds the new record of 111 T-shirts. His time came in at an almost-equally quick pace of 2 hours, 47 minutes, and 55 seconds.

But it’s not as simple as wearing the shirts and running 13.1 miles (though that is arguably the most difficult part). It took Rush’s support team around 25 minutes to dress him, and the shirts added about 40 pounds of weight. “My arms lost circulation and after a couple of hours, my hands swelled to what felt like twice the size, my normally loose wedding ring was a constricted ring, and I couldn’t even touch my thumb across my hand,” Rush said in a press release.

As if running with little to no circulation and extra pounds weren’t enough, Rush also documented a lot of the race, providing a first-person perspective on just how difficult the accomplishment was.

Rush is an avid Guinness record breaker, and he does it all in the name of promoting STEM education. He’s broken more than 200 Guinness World Records to date.
