PORTSMOUTH — Herds of runners and walkers turned out for Sunday’s 10th annual Celebrate Pink 5K that sent waves of the symbolic color over Memorial Bridge and back.

The run/walk benefited My Breast Cancer Support, a local nonprofit providing financial and emotional support for patients on the Seacoast and in southern Maine. Current statistics show one in eight women will be diagnosed with breast cancer in their lifetime, and more than 2,700 new cases will be diagnosed in Maine and New Hampshire this year alone.

The start and finish line at Portsmouth Middle School was flooded with pink tutus, sequins, glitter, fairy wings, cowbells, wigs and tie dye. Inside the school were dozens of vendors offering support and education services to breast cancer survivors and all participants.

Jennie Halstead, executive director of My Breast Cancer Support and a cancer fighter herself, told Sunday’s participants, “Whatever brings you to us, it’s a beautiful bittersweetness that binds us.”

Halstead recognized three particular women in the crowd who have participated in all 10 run/walks since the beginning. She said together, the group was celebrating survivorship, and honoring those who could not be there with them.

Staff members of Dover Women’s Health were participating in the event for the first time this year, and one even pulled a dog in a wagon.

“We’re passionate about supporting all of women’s health,” said Emily Skinner, of Kittery. “We’re here for all of our patients with breast cancer, our family, friends and loved ones.”

Tresses Hair Salon and Spa in Rochester had 20 people participating between staff, family and friends. The group easily won best attire at Sunday’s event, with each runner wearing fairy wings with breast cancer ribbons on them and pink leis around their necks.

“Breast cancer has always been a huge thing for me,” said salon owner Christine Colonna. “I’ve lost loved ones, had friends and family members affected by it. It can affect any of us. As a primarily female industry, this is something we can do.”

Katja Becksted, of Portsmouth, was a survivor taking part in the race for the “sixth or seventh time.” She’s been in remission for seven years, she said. Her team name? “Team Katja.”

“This group helped me go through it,” she said. “It was just amazing. And I love that this organization is local. It’s an awesome organization.”

Becksted’s teammate Nancy Eames, of Hampton, is also a survivor. It was her third year running.

“To support local people that are going through cancer, and it’s a great organization,” Eames said. “They deserve our support.”

The course brought runners over the Memorial Bridge, around the John Paul Jones Memorial Park in Kittery, and back to Portsmouth Middle School.
