To passers-by, friends and colleagues, there is nothing unusual about Sarah Anderson.
As she beams confidently while posing with her father Alan and sister Emma, she appears fit and healthy like any other 22-year-old.
But, unlike most her age, Sarah's morning routine started with 20 tablets - a reminder of the illness she has and for which there is no cure.
At age five, Sarah was diagnosed with cystic fibrosis. In running the 12km leg in the HBF Run for a Reason, she hopes to draw attention to the illness to raise money for a cure and promote the benefits of staying fit.
Doctors who diagnosed Sarah with her illness told her parents she stood the best chance at a longer and healthier life if she took part in sport.
She credits swimming and running for maintaining her fitness.
"I've been swimming competitively since I was young," Sarah said.
Her sister Emma brought together a group of family and friends to run in Team Sarah and they hope to raise $10,000 for Cystic Fibrosis WA.
The Anderson family said other fundraisers were encouraged to join their team when registering for HBF Run for a Reason, which is on May 25.
