About the Event

On October 17, 2026, E3 hosts its 21st annual 2K/5K Fun Run, inviting runners of all ages to celebrate the joy of movement and community. The festivities kick off at 7:45 AM with a whimsical theme titled "Once Upon a Fun Run," promising an enchanted morning filled with laughter and camaraderie.
Participants can look forward to more than just a race; this event is designed to foster connections through shared interests like reading. By bringing a gently used book from the TK-8th grade range, runners have the opportunity to exchange it for another title at one of the designated stations along the route. This unique feature not only encourages literacy but also adds an extra layer of excitement and interaction among attendees.
As you cross the finish line, enjoy light refreshments and enter into raffles for a chance to win exciting prizes. Whether you're running with family or friends, this event offers something special for everyone, blending fitness with fun in a magical setting.
Join us on October 17th for an unforgettable morning of racing and revelry at E3's 2K/5K Fun Run!
