The high noon sun didn't keep Relay for Life teams from setting up signs, pitching tents and unloading trucks to raise money for the American Cancer Society.
Lisa Sudderth's involvement began with two women diagnosed with breast cancer.
"We worked real hard to raise some money to help support them as they traveled to Tulsa for treatments and then sort of out of that we decided to go ahead and develop a Relay for Life team," said Sudderth.
She's the captain of the Rack Pack, a 17 member team made up of coworkers, friends and family.
They spent the hot afternoon setting up a tent to sell barbecue dinners for the event. But they're not the only ones preparing.
"We started the event actually at noon when we start setting up as a team," said Kelly Murphy Fryer, the 2013 event chair. "And then we're going close it at midnight this year."
She also said they changed the hours for the twelve-hour event this year to accommodate the Oklahoma heat.
Ardmore Relay for Life's website said more than $53,000 has been raised so far, but Fryer said the most important totals can't be measured.
"I can't put a number on a human life," said Fryer. "I can't put a number on research."
Sudderth said she hopes the 300 walkers and 26 teams can beat the heat with their own burning desire to find a cure.
"I would like to say that it's all for everyone else, but it's not," she said. "You get a high off of fundraising and helping people and being involved in the community."
