Thousands of runners braved the hot temperatures, hitting the streets of Dublin, and crossing the finish line at the Emerald City Half and Quarter Marathon this Sunday.
"We are celebrating Irish attitude and really celebrating a healthy, active lifestyle," said Race Director David Babner.
And that attitude was epitomized by the example of several firefighters - running in relay teams, wearing 50-70 pounds of gear, including their masks and self-contained breathing apparatus.
"We were sitting around the firehouse wondering how far we could run on a bottle, and we tried it and thought, why not run a half marathon." said firefighter Nick Thornton.
And though they are proving something to themselves to prepare to better serve their neighbors, this exhaustive effort has a deeper, special meaning. They ran on behalf of the families of the Granite Mountain Hot Shots, a group of 19 Arizona firefighters who lost their lives in June, doing what they loved.
"There's been some struggles for them to get compensation, we're trying to do what we can through the International Association of Firefighters, and help support them through any fundraising efforts we can do," said Capt. Mike Reibel of the Washington Township Fire Department.
For these firefighters, it's a way to reach out and give back - like they do every day on the job.
This is the second year these firefighters have run in full gear with their breathing apparatus. They are all members of a special group called The First Due Endurance Racing team.
Departments represented include Columbus, Franklin Township, Grandview Heights, Mifflin Township, Upper Arlington, and Washington Township.
