St. Louis (KSDK) -- Her goal is ambitious; her days a little repetitive at the moment.
"It literally just started as a crazy dream in my head," explains Colleen Caul, a 29 year old St. Louis woman.
Since July 21st, she's been lacing up her shoes, slipping into her shades, bathing in sunscreen and running 15 miles a day.
When it's over, she will have run 1,000 miles through eight states in 65 days.
"Chocolate milk, after every run the best thing to drink within 15 minutes is chocolate milk," Caul points out as she opens the fridge.
Every cabinet is also crammed with cookies since she needs to consume between 5,000 and 6,000 calories a day.
"This is the magic binder and it has our day by day route," Caul says pulling out the binder.
We caught up with her and Tom, who's driving the RV and documenting the whole thing on day six.
"So we've done about 77 miles or so, so far, what is that 923 or something like that, but actually when I start thinking like that, I shut my mind off and say no, no, no just think about today," Caul explains.
She also thinks about the reason she's doing this because with every step, she hopes to bring a little more attention to cystic fibrosis.
"This woman in Green Castle, Indiana contacted me about eight months ago and her best friend has two kids with CF and she said she wanted to run 50 miles of it with me," Caul says.
Caul is running for her little sister.
"A lot of people hear about cystic fibrosis and feel removed from it, but no one in our family had cystic fibrosis before Katie," Caul points out.
"They've come very, very far in the past 20 years and there's incredible treatments for it, but there's still not a cure, so they still need the funding. They receive very little federal funding," Caul goes on to say.
So every day now until September 23rd, she'll be running towards the Big Apple, and hopefully, to a cure.
At this point, Caul is in Ohio and by the end of today she will have run 418 miles. You can follow her journey on her blog.
