Can you imagine running from the Calgary Airport to the Edmonton Airport?

Well, Dave Proctor just jogged that exact distance — 260.4 kilometres — over 24 hours, on a treadmill. And he only took six bathroom breaks.

"Even to me at this point, that sounds a little bit unreal. But, I was there every step and it hurt pretty bad," the "exhausted" ultramarathoner told the Calgary Eyeopener on Monday.

"It's kind of like getting over jetlag but a really, really bad jetlag."

Proctor ran from Friday at 4 p.m. to Saturday at 4 p.m. at the Calgary Marathon Expo in the Big Four Building, unofficially setting two Guinness World Records for running the most distance on a treadmill in 12 and 24 hours.

And he wasn't alone.

Altogether, Calgary runners set six world treadmill running records this weekend — raising more than $75,000 for MitoCanada, which supports families impacted by mitochondrial disease.

"Really it's a disease that has no cure," said Proctor. "We thought, 'let's go big.' You know the only way to really create a lot of attention is to create a circus."
