CEDAR RAPIDS, Iowa - People spent part of Saturday stretching their legs trying to stretch out awareness for kidneys.
This morning at Noelridge Park brought the 2013 Iowa Walk for PKD -- that's polycystic kidney disease, a genetic disorder that affects thousands.
Saturday's walk was part of at least 50 across the nation to get the word out about PKD and how many people are impacted by it.
One race leader also says the symptoms of this disease can go undetected.
"It can be anything from lower back pain to no symptoms at all," said John Burge of the PKD Foundation.
Burge says about 6,000 Iowans are directly affected by PKD.
