  We look forward to seeing you at the starting line on May 16, 2026!

  The Run for D103 5K Run/Walk is a family-friendly, annual fundraising event that enables the Parent-Teacher Organization (PTO) to provide the Lincolnshire-Prairie View School District 103 with programs and equipment for the benefit of our children. This race is representative of our district's commitment to foster both healthy minds and healthy bodies in our children and to instill a lifelong passion for education and exercise.

  In addition to the 5k, we will host the Sibling Shuffle, a free fun run for children ages 4 and under. Toddlers will have a chance to toe the line and be just like their older sibling(s) in this 103-yard dash to the finish line. Each participant will receive a participation medal to celebrate his/her achievement.

  Since the Run for D103 is a family event, we kindly ask you to please leave all furry friends at home. Registered service dogs are always welcome.

  Please note we CANNOT GUARANTEE T-SHIRTS for registrants after April 15, 2026. After that date shirts will be distributed on a first come, first served basis based on inventory and registration date/time.
