Team Boston is one of six teams participating in the fundraiser. Its members had supper at UnityPoint Health — Trinity Regional Medical Center Thursday. They stayed overnight with local residents and will leave Fort Dodge today.

Caroline Watson, of Lyme, New Hampshire, said her team has raised about $185,000 so far.

There are 28 members aged 19 to 25.

Each has a connection to the disease.

“All of us have been touched by cancer,” she said.

During their stops, they do service work, volunteering, for example, at cancer centers.

“We’re young adults wanting to make a difference for other young adults,” she said.

The entire group doesn’t all run at once.

“We run in relays with a different running partner each day,” Watson said. “We do two to four miles at a time. Each runner will do 10 to 13 miles a day.”

The Ulman Cancer Fund provides a variety of services including Cancer to 5K, a 12-week program designed to reintroduce cancer survivors to physical activity;patient navigation; one-on-one support and resources for young adults. The fund also provides scholarships for young adults to continue their education and the UCF House, a home in Baltimore, Maryland, that will open this fall to provide a place to live while undergoing treatment.
