PALOS HILLS, Ill. (CBS) -- On Sunday, 40,000 runners will weave through the city for the Bank of America Chicago Marathon.

Laura Brown, a Tinley Park mom and English teacher at Amos Alonzo Stagg High School in Palos Hills, is going the distance for two very special spectators – her children. She is seeking to raise awareness about a neurological disorder they both have.

CBS 2's Sabrina Franza talked with Brown on Thursday. Brown said running a marathon started as a bucket list item.

"One and done, as they say," she said.

That was in 2012. Now, a decade later, she is following a 20-week training program and lacing up to do it all again, and this won't only be the second time.

"This weekend will be my sixth time running specifically the Chicago Marathon," Brown said.

The reason why Brown runs the marathon is about more than a medal.

"Both of my children have a very rare medical condition called CCHS, which stands for congenital central hypoventilation syndrome," she said.

Brown's son Robbie is 7, and her daughter Josie is 5. They are two out of just 1,200 people in the world diagnosed with the genetic condition.

"When they fall asleep, their brain stops sending a signal to the respiratory drive to breathe properly."

Both kids can only sleep with a BPAP machine – a type of ventilator.

"We can't let them go to bed at night without being hooked up, as we say," Brown said.

The condition is so rare that Brown said funding for medical research can sometimes be hard to come by. That is why she is running 26.2 miles for the sixth time.

"I like to think that even though this has affected us so personally, there is a purpose for us to be able to bring awareness to this cause," Brown said.

Brown's biggest fans have taken their diagnoses in stride. Their names are etched into mom's laces.

Come Sunday, Robbie, Josie, and Laura Brown's husband, Jeff, will be cheering her on. What is less clear is who will be most proud at the finish line.

"I don't know how many adults can say that a 7-year-old and a 5-year-old are their hero, but my kids are absolutely my heroes," Brown said.

A GoFundMe page has been set up to help raise money to support the CCHS Family Network. You can find it at this link.
