PORTLAND, Ore. -- Dig out those retro workout clothes. A Portland group wants to bring life back to a fitness trail along Terwilliger Boulevard that was built back in the 1970s.

If you've run along the path, you may have seen remnants of old school style exercise equipment, such as some old rings or bars.

They are all part of the old Portland Exercise Course. And don’t feel bad if you didn’t know that course existed. Not many people do.

"It is reminiscent of the president’s challenge you had to do in elementary school," said Wendy Gibson.

Gibson runs along Terwilliger about three times a week. She would love to see the old course brought back to life.

The course was built back in 1974. It was the idea of a former Wilson High School track coach. It runs alongside a two-mile stretch of Terwilliger and was made up of 20 exercise stations. Some of those stations are still there.

“The bones of the course is there,” said Wes Risher.

Risher is with Friends of Terwilliger. The group wants to renovate the old course, clean up the tattered equipment and rebuild the exercise station.

“Ideally, we would like to create a mobile app where people could find each station on their phone and get some direction of what to do at each station,” he said.

The group will be meeting with Portland Parks and Recreation to discuss the plan, including options to pay for any improvements.
