The race must go on, and for the Sole Sisters, it's going on in memory of one of their own.
Robbie Brooks, who the A2A 5K has now been named after, was a member of a group of Ardmore runners known as the Sole Sisters.
The Sole Sisters began when the group of women was at a race in San Antonio. They had shirts printed with the name, which stuck.
The group of women regularly train together and travels to races together. They have ran in Dallas and the Oklahoma City Memorial Marathon.
"We try to get together as much as we can during the week, and then do long runs on the weekends," Julie Keys said.
The A2A 5K being renamed in Brooks' honor means a lot to those who ran with her.
"It's something Robbie would cherish — to know we were running in her memory," Keys said. "She was outgoing and always surrounded by cancer. She was an advocate for all sorts of cancer raising organizations."
As an avid runner, the 5K represents a beginning for the sport.
"She (Brooks) really loved the 5K because it brought out local support and people new to running. It's very fitting the race is named after her," Jo Fuller said.
Yet, the Sole Sisters often find themselves volunteering at the A2A more often than running in it.
"If we didn't have it here, it would be a strain on families. It's good to know it's nearby," Keys said.
Keys has served as the registration chair since the second year of the race. The first year, she ran the marathon.
Sometimes, Keys and Brooks would go and help other runners as they complete the race.
"We just helped them run in, and I needed to run anyway," Keys said.
Fuller is in charge of awards and medals for the A2A.
"It's the best job on the course because you get to see the excitement and see everyone cross the finish line," she said.
She will next be running in the half-marathon at the Oklahoma City Memorial.
"It's a neat race, and they are very supportive of the A2A," Fuller said.
