Colorado River Trail Run
An event of multiple trail distances set along the Colorado River at McKinney Roughs Park in Cedar Creek, Texas. The course follows riverbanks and varied single-track and dirt trails through natural habitats and includes some technical sections and moderate climbs and descents.
Distances offered include:
- 200K ultramarathon
- 100 Mile ultramarathon
- 100K ultramarathon
- 50 Mile ultramarathon
- 50K (31 miles)
- Marathon (26.2 miles)
- Half Marathon (13.1 miles) and Half-Marathon Ruck
- 10K (6.2 miles)
- 5K (3.1 miles)
The event features fully stocked aid stations with hydration, nutrition, and medical support. Organizers state they use waste reduction and sustainable materials as part of eco friendly practices. Pacers are permitted for the longest ultramarathons and must follow event rules: one pacer per runner, age and check‑in requirements, entry and exit at aid stations only, no physical assistance, and a nominal pacer fee.
The Half-Marathon Ruck uses the same trail and cutoffs as the half marathon. Ruck rules require a dry minimum pack weight of 20 pounds for participants under 150 pounds and 30 pounds for those 150 pounds and over; water does not count toward the minimum. Weigh in and finish checks are required and participants must carry their own pack for the entire course.
Volunteers are recruited for course marshals, aid stations and registration support; volunteers receive a race shirt, snacks, community service hours and future race credit. Registration by November 7, 2026 guarantees a race shirt. Visit the organization's website for the most recent information.
