The Upper Michigan Brain Tumor Center helps around 40 people each year, but even more people are helping the center operate.
Nine year old Maddie Challier lost her grandmother to brain cancer last September.
However, Maddie wanted to do something more for Upper Michigan Brain Tumor Center in honor of her grandmother.
"I thought no one really talks about brain cancer just breast cancer so I wanted to help raise money for brain cancer," said Maddie Challier.
With the help of her school she raised $721 for the Center, but she's not the only one helping.
More than 600 people are expected to help raise funds through the 9th Annual Hope Starts Here Challenge.
"Brain tumors really do affect many in our community and surrounding communities. To have that many people come together to celebrate those lives and to remember those people , to us the biggest part of the event," said Dr. Rob Winn.
The challenge is a mix of competitive and family events including a half marathon, a 5/10k, and a leisure cycle walk.
"The event has changed, but what we do with the money really hasn't changed it still supports patient needs, and research with the students."
The challenge happens Saturday at the Lakeview Arena in Marquette.
They're hoping to collect 20 thousand dollars.
As for Maddie she will honor her grandmothers' memory by participating along with her entire family in the challenge.
