LEESBURG — Leesburg resident Lynda Cowin Nijensohn will be one of 30,000 people running in the 122nd Boston Marathon Monday, but you wouldn't know it because of the name on her singlet.

The name she wants people to notice, remember and chant during the race is Wendy Daniels Koontz.

In a Facebook post Thursday, Nijensohn wrote, "I will be 'WENDY' on race day. I will gladly hear others yell Wendy as I run. She will be with me in mind, spirit and soul! Wendy passed away recently on March 29th at the young age of 40 after a brave fight against brain cancer. This is for you Chad Daniels, your sister’s beautiful children, your wonderful parents, her loving husband and all of Wendy’s dear friends and family. Let’s find a cure to stop this unbearable pain.”

Chad Daniels said this will be the first time he watches the Boston Marathon and attributes that to what Nijensohn is doing in remembrance of his sister.

Koontz was recently living in Arlington, Virginia, with her husband Robert and two children Piper and Charlie. She was born and raised in Leesburg, graduated from Leesburg High School in 1996 and upon her death, Koontz left many people in Leesburg behind, including family and loads of friends.

For the eighth time, Nijensohn will be running to help raise money for the Dana Farber Cancer Center in Boston, the place she was treated for breast cancer nine years ago. She said this is the first time she's dedicated her singlet to one specific person.

“Wendy was a very dear friend to some very close family friends, and when I heard she’d died, it just really touched me,” Nijensohn said.

Koontz's death made her realize how close they were in age and how they were both wives and moms of young children. She said it also made her feel even more grateful she beat cancer, and it grew her passion for raising money for cancer research.

Daniels wants his sister’s name to help bring awareness to how cancer affects so many people. He said his family is honored by Nijensohn's gesture.

“No one wants to say goodbye to their children, sister, mom or friend, but when someone passes, it’s very emotional to see how they were loved by so many,” Daniels said. “The fact that she reached out to us to do what she’s doing is very nice.”

Daniels gave Nijensohn some photos of Koontz and her family so she could put them on her singlet.

Nijensohn plans to give Koontz’s family the singlet after the race on Wednesday in Leesburg.
