Tom Perri has run a marathon in all 50 states and now the 60 year old will run his 60th marathon after his stage 4 prostate cancer diagnosis.
He has won around 100 marathons so far. This new challenge is next month in North Dakota.
"The most common question I get is, 'What's my favorite marathon to race?' And I say, 'It's always my next one, because I'm not guaranteed that next race," Perri says.
“I could either just sit in the chair and watch life go by," he says, "or continue life as is and maybe be a runner, but just not as fast as I used to be.”
Perri's best time for a marathon was in 2007: 3 hours, 35 minutes, 42 seconds.
