Tri Zones Training

The Decker Challenge is tough course that follows the Danskin Bike course. The race is put on by the Austin Runner's Club.

The course runs through Zilker Park and the awesome Trail of Lights, with more than 180,000 lights. The entry fee also includes a "Trail of Lights 5K" long sleeve t-shirt designed by a local artist.

The Fun Run will benefit the Round Rock YMCA, STARRY, Round Rock Habitat for Humanity and the Round Rock ISD Education Foundation. There will be food and drinks provided along with activities for the kids, live music and family fun. We encourage school groups/teams, community organizations, and local businesses to wear their organization’s shirts and come show your support. Grab the family and friends, your running shoes and come help make a difference.

This family-friendly event features photos with Santa, kids games, costume contests for people and pets, a health and safety fair. All registration fees include a long-sleeved t-shirt and participation at event activities. We welcome participants of all kinds. We provide the bells...you provide the spirit!
