Mosaic Trail Race

Mosaic Trail Race

Mosaic Trail Race is a trail running event held December 5, 2026 at Indian Mound Ranch in Liberty Hill, Texas, near Austin and Georgetown. The event features multiple distances and a youth 1 mile run on ranch trails along the San Gabriel River.

Distances include:

• 50K
• 26.2 mi
• 13.1 mi
• 15K
• 10K
• 5K
• Youth 1 mi

The course is laid out like an infinity symbol with two main 5 km loops. The west loop is mostly flat but technical in places with short climbs, twists, bluff overlooks, and ravines. The east loop mixes open pasture running and flowy single track with no extended climbs. Half and full marathon distances use an added section to create 6.55 mile laps. The youth mile follows a shortened route and a marked shortcut.

Course markings include orange caution tape, yellow arrows, and confidence markers; signs indicate turns for each distance. Aid stations will offer basic support and the event is cupless, so participants need personal cups or bottles; collapsible cups may be available for purchase at packet pickup. Chip timing is used with ankle chips collected after finishing. Pacers are not allowed.

The event follows Leave No Trace principles. Camping and spectator vehicle access at the ranch require cash fees and specific parking rules near active railroad tracks. Visit the organization's website for the most recent information.
