Colleen McGowan, of Herndon, Va., said that she thought hard about her support for Komen when the group decided to reinstate funding for Planned Parenthood. She said she understands why people on both sides of the issue may choose not to support the group.
Others weren't so understanding.
About a dozen protesters stood at the finish line demanding Komen pull Planned Parenthood funding once again.
"I am shocked that a noble, respected group like Komen would associate with Planned Parenthood," said Kurt Linnemann, executive director of the Center for Bio-Ethical Reform, an anti-abortion group, which led the protest.
The race secured both local and national supporters, including Bank of America, Yoplait, Walgreens and Self magazine.
In other parts of the country, local affiliates are losing supporters.
Komen Puget Sound in Seattle sent an email Friday saying registrations were down 50 percent from last year and pleading for support.
The Race for the Cure in southern Arizona last month drew 7,200 runners and walkers, compared with 10,000 last year. Donations, registration fees and corporate sponsorships were roughly $560,000, well below the $700,000 goal.
Spokeswoman Gillian Drummond said that officials with Komen Southern Arizona had increased their marketing efforts to draw supporters to the race, but that the Planned Parenthood incident was still on people's minds.
"There were still a huge amount of people who felt like they couldn't trust the brand anymore," she said.
Drummond, who said the race is the organization's biggest fundraiser, added that she hopes people will slowly start to trust the organization again.
"It has to get better next year," she said. "We are talking about people's lives here."
Donations for the Southwest Florida Race for the Cure in March declined about 15 percent, to $850,000 from last year's $1 million, according to news reports.
Organizers of the race in Indiana this weekend also said registration and donations have declined. They expected about 26,000 people to participate, down from 37,500 last year. Funding was expected to be down about 32 percent to 33 percent.
Dana Cruish, executive director of the Central Indiana Komen affiliate, said the economy and gas prices also contributed to the declines, but she blamed them mostly on the Planned Parenthood incident.
"People have strong feelings on both sides of the issue and have chosen not to participate," she said.
In March, Cruish sent a letter to past participants asking them to continue their support. She reminded them that women need the services Komen helps fund.
"You think you're hurting Komen," she said. "But it's not really Komen who will be hurt. It will be the people who go to their local grantees for a mammogram and the grantee has run out of money."
She said that the appeals have helped bring people back and that she hopes the strong feelings will eventually fade.
"I think that the anger will die down," she said. "I think it's up to Komen affiliates to make sure we're really telling our story."
In Maryland, Fowler said the Komen affiliate worked to spread the message that it had never funded Planned Parenthood. The group also tried to separate itself from the national organization and focus on local work. Seventy-five percent of funds raised stay in the state, Fowler said.
"We tried to drive home that every dollar raised really could help your mom, your sister, your neighbor or your co-worker," Fowler said. "We have been fortunate that translated well and people have been able to understand that."
The group is looking to make the Ocean City race a destination event. This weekend, participants came from more than 20 states.
Organizers expect to grow the race over time. The Hunt Valley race started with just 2,500 runners, Fowler said.
