About this race
Come join us at Spring Park for a fun filled morning. Lace up your running and walking shoes and get ready to enjoy a scenic route through the park while supporting a great cause. Halloween and Dia de los Muertos costumes are highly recommended but not required. For those of you that don't know her, Jenny Buls-Vrba was an avid runner and triathlete that was tragically taken from this world too soon and we want to celebrate her by doing what she loved.
Whether you’re a seasoned runner or just looking for a good time, this event is perfect for all ages and fitness levels.
After the run, stick around for food and a silent auction at Rusty’s Last Call in Osage. It’s going to be a great day as we remember Jenny and her favorite holiday season. The $30 registration fee will include a Sugar Skull Fun Run T-shirt and Soup at Rusty’s following the Fun Run. All proceeds will go to the Jenny Buls-Vrba NIACC Women's Basketball memorial scholarship, the Jenny Buls-Vrba Crestwood High School memorial scholarship, ISU Small Animal Veterinary Hospital as well as the Humane Society of North Iowa.
Registration will begin at 9:00 am with the Run/walk to begin at 9:45. Soup, snacks and silent auction to follow at Rusty’s Last Call in Osage.
Please note: Parts of the trail may be rocky and therefore no racing spikes are allowed!
