Last year, this event raised $2,600 for Fostering Hope, an organization that assists local children in foster care. Participants have three race options: The Festive Four(ish) Miler will encompass four loops around Grand Park Lake at Market Commons. The Kids Fun Run will complete 800 meters around the lake. The Jurassic Jaunt features you dressed in your favorite costume for a 50-yard dash along the lake. All participants receive a custom designed finisher medal (finisher medal for the 4 Miler and Kids Run only) and option of purchasing a hoodie and/or T-shirt.
