While working at a water stop during the Boston Athletic Association 10K road race on Sunday, three Parkway Running Club members saved a man's life when he collapsed in Back Bay.

"There were about 20 Parkway Running Club (PRC) members volunteering at the water stop to hand out water to the runners; there were about 5000 runners in the race.  At one point during the race, a runner ran up to the water stop and collapsed right in front of the PRC members giving out water," said Jim Sweeney, president of the PRC.

Three volunteers - Jill Hallisey, Reyna Lounsbury and Karen May - immediately jumped into action and found the man had no pulse, and began administering CPR. 

A Boston Athletic Association volunteer at the water station radioed quickly for Boston EMTs to come to the water station near the intersection of Commonwealth Avenue and Berkeley Street. The Boston Athletic Association also puts on the Boston Marathon, and was the organizer of the 10K road race.

About four-tenths of a mile from the finish, the three Parkway Running Club volunteers continued CPRs for several minutes. Another runner, and an emergency room nurse, also stopped to assist, said Sweeney. 

"They kept the fallen runner alive until Boston EMS and the ambulance could arrive. There were Boston EMS medics on bikes patrolling the course during the race. They had adefibrillator with them and used it on the fallen runner when they arrived," said Sweeney.  

The Parkway Running Club members still don't know the man's name who they saved.

"We understand from the BAA that he stayed overnight at the hospital and that that he is now doing well. We don't know the name of the runner who collapsed or the other runner who came to assist doing CPR, " said Sweeney.
