Thanks to the efforts of a good Samaritan who performed CPR, a Roanoke, Virginia, man is recovering after he suffered a heart attack 15 miles into a solo run Saturday, The Roanoke Times reports.

Lisa Broyden, 52, of Blacksburg, Virginia, was in town because her daughter was taking tests at a nearby school. The Roanoke Times reports that she decided to go for a walk while waiting for her daughter, and came across Joe Salmon, 62, who was lying on the ground.

At first, Broyden, who had recently completed a required CPR course for work, mistook Salmon for a CPR dummy.

“It was a thin athletic-looking person on the ground. In the course, the dummies are actually dressed in gray pants and a blue warm-up jacket,” Broyden told The Roanoke Times. “There were a bunch of people looking worried, and I thought, ‘Holy cow. This is not a drill.’”

Broyden performed CPR until EMS workers arrived and were able to restart Salmon’s heart with a defibrillator, The Roanoke Times reports.

Though Broyden, an occupational therapist, is required to take a CPR course for work every two years, she never expected to have to perform CPR.

“I’m usually in a hospital, so I always assumed there would be real doctors or people who know what they’re doing,” Broyden told The Roanoke Times.

Salmon’s partner, David Hurley, told the Roanoke Times that though he and Salmon both have IDs to wear, they hadn’t yet had them engraved. Hurley only learned Salmon was in the hospital when he called Salmon to find out why he had not yet returned from his run.

Hurley also said that Salmon, who works at a Roanoke elementary school, often runs on more remote trails.

“Sometimes he runs up on the mountain or on the parkway,” Hurley told The Roanoke Times. “If he had chosen to run up there that day, he would be dead.”

During Salmon’s time in the hospital, Hurley posted updates about his condition on Facebook. On Thursday morning, he reported that they were hoping Salmon could return home soon.

“He has made great progress; however, there will be long term speech/language therapy for memory issues and also some physical therapy. Thanks to all of you for your prayers,” wrote Hurley.
