PORTLAND, OR (KPTV) -

Just imagine running on a treadmill in space. Well, you simply can’t do it without gravity. So a local designer built a harness that duplicates a person's body weight and makes space-running possible.

It’s called the Glenn Harness and it’s made by Terrazign in Portland.

President Bill Dieter said they started making them for NASA about eight years ago so astronauts could exercise to maintain muscle mass and bone density.

Earlier this week, the Glenn Harness was used by British astronaut Tim Peake when he ran the London marathon in space.

The harness looks like a heavy-duty backpack, minus the pack. It has long straps that hang down past your hips and attach to the treadmill itself, creating weight and resistance.

Dieter said it definitely works, but it takes a lot of getting used to.
 
“It did the job, but he said it was weird running in it, which all astronauts say. The motion of being held down while you run is not natural, but it is what it is and it’s the best we can do right now," Dieter said. 

Dieter says Terrazign makes a handful of the harnesses every year and they’re used in all U.S. based space station missions.
