5K Races at Star Ranch
Run free, have fun, and make unforgettable memories at the Star Ranch 5K events — two of the most unique and talked‑about races in Texas!
Star Ranch has proudly hosted the Bare Buns Run 5K Fun Run every spring since 1997. This long‑running favorite draws runners from across the region and is part of the AANR‑SW 5K Series. To keep the experience personal and enjoyable, participation is limited to 200 runners per event.
Thanks to the overwhelming popularity of the Bare Buns Run, Star Ranch now hosts a second annual race: the Chilly Cheeks 5K Run in the fall. Together, these two events give runners twice a year to enjoy fitness, freedom, and fun in a relaxed and welcoming environment.
The Course
Set in scenic McDade, Texas — just 30 minutes east of Austin on US Highway 290 — the Star Ranch 5K course offers a refreshing change from typical road races.
Runners begin with a beautiful rural stretch through open pastures and shaded woodland trails for approximately three kilometers. The course then transitions into the heart of the ranch, where the final two kilometers wind along sand and gravel paths connecting charming cottages and cabins.
The finish line awaits at our stunning pool area, where you can relax, cool off, and enjoy a light meal fresh off the grill while cheering on fellow runners and waiting for race results.
Make a Day of It
Your registration includes admission for one guest, and you’re invited to stay and enjoy everything Star Ranch has to offer. After the race, stick around for games, activities, and plenty of opportunities to relax, socialize, and celebrate your accomplishment.
Whether you’re chasing a personal best or just out to have a great time, Star Ranch 5K events deliver an experience you won’t find anywhere else.
