62-year-old former competitive runner Evans Wilson has suffered from pulmonary fibrosis and pulmonary hypertension for the last five years, but his condition didn't stop him from finishing the Seattle Marathon over the weekend to raise money for the Pulmonary Fibrosis Foundation. Wilson shared his story on the crowdfunding site FirstGiving, and has raised more than $19,000 to aid “ability of those who have [pulmonary fibrosis] to finish their race in life.”

Wilson is unable to run, and he and his wife had to wheel along oxygen tanks with them along the route. Knowing that he wouldn't be able to finish the race in the allotted time, Wilson received permission to start earlier than any other participant, and continued walking after the course had closed. He livetweeted the marathon on his Twitter account.
