The sixth annual “Run for Your Buns,” a 5K or 10K run/walk to benefit colon cancer prevention, is set for 8 a.m. Saturday at Lincoln Park in Grand Forks.

Proceeds from the event are given to the Altru Health Foundation to be used to pay for colonoscopies for Altru patients who are uninsured or underinsured, said Kamrin Macki, race director.

Online registration is open through midnight on Tuesday. Participants may also register from 4 to 8 p.m. Friday at See Dick Run, 3750 32nd Ave S., in Menards strip mall, Grand Forks. On-site registration is set for 6:30 to 7:30 a.m. Saturday.

The cost is $25 per person for the 5K and $35 for the 10K.

Participants finish the race by walking or running through a three-dimensional facsimile of a giant colon.

For the first time this year, participants will be offered “memory bibs” to wear on their backs, said Macki. On the bib, they can write the name of the person they’re honoring or remembering by their run or walk on the Grand Forks Greenway.

Also a first this year, Grand Forks police and firefighters are waging a friendly competition, five on each team, for bragging rights. The winning team receives a box of doughnuts, if the police win, or popcorn, if the firefighters win.

Over the past five years, the event has raised more than $31,000 to support patients who can't afford colonoscopies, said Macki, a nurse practitioner in Altru’s gastroenterology department and a runner, who started the event.

“It was a way to blend my two passions, and raise funds for colonoscopy screening,” she said.

In her work, Macki has seen patients benefit from early detection of colon cancer as a result of support from the fundraising efforts, she said.

Over the course of a lifetime, one in 20 adults will be diagnosed with colon cancer, according to the American Cancer Society.

Colorectal cancer is the second-leading cause of cancer death in the United States among men and women combined. About 60 percent of colon cancer deaths could be prevented with screening.

A total of 140,250 new cases will be diagnosed in 2019, according to the ACS.

In the Run for Your Buns race Saturday, winners in each category will be announced during a program beginning at about 9:30 a.m., Macki said.

There also will be a drawing for gift cards donated by local businesses, she said.
