Korlu Bosillo, Arlington :: ran her 50th 5K in May and the Ultra Spartan 30-mile obstacle course in October. Although she was on the track team in high school, she had stopped exercising and gained weight. She competed in her first 5K in April 2013 and now competes in about one race per month, including three Spartan obstacle races. “I believe it is important for everyone to establish a regular exercise regimen and go outside and run, even if it is just once a month,” Bosillo says. “I believe that once you start running, you can be a runner for life.” She has worked as a scribe at Cook Children’s ER and Family HealthCare Associates and has been a scribe/medical assistant at Arlington Orthopedic Associates since May 2017.
