Hundreds of families walked in the first ever Cure Search Walk in southwest Houston.
The event raised money for children's cancer research.
Some young patients who participated in the walk received medals from doctors.
There were also other children's activities and prizes for the teams that raised the most money.
Organizers say cancer is the leading cause of death by disease in children.
Volunteers in the Rice Village area on Saturday also pitched in, but they used their heads instead of their legs.
They agreed to shave their heads to raise funds for the Saint Baldrick's Foundation.
More than 50 volunteers had their hair sheared at Brian O'Neill's Irish Pub on Morningside.
The event surpassed its goal of raising $15,000, and some of that money stays right here in Houston, funding research grants at Texas Children's Hospital and M.D. Anderson Cancer Center.
The Saint Baldrick's Foundation has raised more than $126 million to fund childhood cancer research in the past 12 years.
