FOX19 - A married mother-of-three, who had been running in a Pennsylvania half marathon, died after completing the race.
Lindsay Doherty, 36, had made it to the end of 13.1-mile race on Sunday when she suddenly collapsed.
The mom had taken up running a few years ago to train for Scranton's Half Marathon, Philly.com reported.
Emergency medical workers rushed to assist Doherty and attempted to resuscitate her, but she died a short time later at a local hospital.
The Lackawanna County coroner planned an autopsy on Monday.
The Scranton Half-Marathon Committee released a statement addressing the tragic incident.
"While we painstakingly prepare in advance for situations like this, we are saddened when an actual emergency occurs and the outcome is not favorable. 'This is a difficult and tragic situation and on behalf of the race committee and all of the runners who participated today, we extend our deepest sympathies and ask everyone to keep this family in their thoughts and prayers."
The Roman Catholic Diocese of Scranton said the mother and avid runner worked in its development office, raising money for Catholic education.
A special prayer service was scheduled for Monday night at St. Paul's Parish in Scranton, where she was a member.
Doherty was described as 'vibrant' and 'tireless', by her friends and neighbors. The Scranton resident had run the half marathon the previous year with a time of 1:55:32.
