Celebrating 10 Races • In Honor of Katie Filling
As we celebrate the 10th Stefanie Ashdown Memorial “Do Your Best” 5K, we also come together in loving memory of Katie Filling, a devoted member of the Stef Ripple community. Katie attended every race and met Stefanie Ashdown while both were undergoing chemotherapy. Her strength, kindness, and unwavering presence reflect the heart of this event. This milestone race honors Katie’s life while continuing the ripple of hope, compassion, and support she and Stef so beautifully embodied.

About Stef Ripple
Stef Ripple was created in memory of Stefanie Ashdown—a Severna Park native, wife, mother of three, daughter, sister, aunt and ovarian cancer warrior. Stef battled the disease for two and a half years with grace, strength, and a beautiful smile that lit up every room. Her energy and kindness were contagious, and the impact she had on others became known as the “Stef Ripple.” She put her children first but always found time to care for others. Stef often encouraged her kids with the words, “Do your best.” In her honor, Stef Ripple continues her ripple effect by spreading the principles that guided her life:
Be Thankful. Be Helpful. Be Kind.
