Don Stevenson estimates he has walked 12 billion steps to cover 60,000 miles over a span of 20,000 hours for charity in the past 20 years.

He admits he has lost count as to how many pairs of shoes he has worn out along the way.

“Hundreds,” he suggested.

At 82 and in excellent health, Auburn’s Pacin’ Parson refuses to slow down. He lives to follow his daily ritual of walking mega miles.

“All for the good of others,” Stevenson said.

The ultra-marathon walker caps off his latest project – to beat amyotrophic lateral sclerosis (Lou Gehrig’s Disease) – with a ceremonial trot around his hometown pathway, Game Farm Park.

The public is welcome to join Stevenson at 11 a.m. Tuesday, June 12 to celebrate his 20-year milestone of walking for charity and see the completion of a 13,000-mile walk devoted to bringing awareness and fighting ALS, a progressive neurodegenerative disease that has no cure.

Money raised on Stevenson’s walk, which began in March, supports the ALS Association.

Stevenson dedicated the walk to Mark Alleman, who was diagnosed with ALS nearly two years ago. Alleman and Stevenson attend the Church of the Nazarene in Bonney Lake.

“Mark’s last wish and dream is that he and his (wife) Maxine will be able to visit the Grand Canyon before he leaves this planet,” Stevenson.

To make the Alleman’s dream a reality, Stevenson and a senior fellowship group at the church are stepping up to raise money for the trip.

As Stevenson explained, none of the monies received for this project will go to the ALS Association. Instead, the money will go exclusively to: The Compassionate Ministries of the Bonney Lake Church of the Nazarene to send the couple to the Grand Canyon in September.

Those wishing to help the family, can write a check to: The Church of the Nazarene, 7410 Myers Road E., Bonney Lake, WA 98391. On the memory line of the check write “Mark’s Journey.”

Stevenson, a U.S. Marine Corps veteran and retired pastor, teacher, truck driver and firefighter, has supported many causes since 1998.

He has covered 7,600 miles for Alzheimer’s; 20,000 miles for Multiple Sclerosis; 13,000 miles for Huntington’s disease; 2,400 miles for the American Cancer Society; climbed Mount Rainier for the American Lung Association; walked 730 miles for Spina Bifida; and 2,086 miles for blind and special needs kids.

Stevenson finished a 300-mile trip around Auburn to raise $10,000 for the Fred Hutch Cancer Research Center. He also completed two 1,000-mile walks and a 500-mile trek in Washington state for the Pulmonary Hypertension Association (PHA),

He made national news when he began a 3,000-mile journey from Auburn to the PHA headquarters in Silver Spring, Md., in 2015, just shy of his 80th birthday.
