Spokane man's journey from brain cancer to running 50k shared in new documentary

SPOKANE, Wash. - Friday night, the journey of one Spokane man who went from a terminal cancer diagnosis to doing a 50k run will be on the big screen. 

Three days before Brad Thiessen was scheduled to run his first 50k trail run, he had to have emergency surgery so doctors could remove a brain tumor. 

After chemo, he started training again to run that 50k race. This time, local filmmaker Adam Harum was along for the run to create a new documentary called "Proof of Life."

"We spent a lot of time together. He was on the trail. He invested heavily in it and it shows," Thiessen said. "There's a lot packed into 20 minutes and it goes by very fast."

Doctors diagnosed Thiessen with brain cancer twice, most recently in 2015. Doctors told him the terminal cancer could come back at any time, so he became even more determined to achieve major goals. 

He was also diagnosed with testicular cancer between his brain cancer diagnoses. 

"Trail running really became sort of my pathway to emotional and physical health," Thiessen said. 

See whether he achieved his 50k goal and the journey along the way by watching his documentary here. It's also being shown at the Spokane International Film Festival at the Bing Crosby Theater at 8 p.m. Friday.
