Pandora's Box Of Rox

Pandora's Box of Rox Trail Race

Pandora's Box of Rox is a multi-distance trail run held at Reveille Peak Ranch in Burnet, TX. The listed date for the event is April 25, 2026. The course uses marked loops and offers routes for a wide range of distances.

• 52.4 mi (double marathon)
• 26.2 mi (marathon)
• 13.1 mi (half marathon)
• 8 mi
• 4 mi
• Youth 1 mi

Loop structure for the longer distances is defined on the course: the half marathon equals one full lap, the marathon two laps, and the double marathon four laps. Shorter distances follow portions of the larger loop and rejoin the main route to reach the finish.

The trails pass through meadows, scenic overlooks, and up and over a large granite dome. The race hub centers on a lakeside pavilion with restrooms, some showers, porta potties, and a finish area that typically includes food trucks and a lakeside pavilion space for spectators. Spectators arriving with a racer in the same vehicle are covered by the racer day use allowance; separate vehicles follow regular park day use fees.

Course markings include orange caution tape, yellow arrows, and frequent confidence markers; reflective elements are used for sections run in low light. Aid stations are staffed at primary locations and offer food, water, electrolyte drink options, and ice at staffed stations; smaller stations provide basic supplies. The event is cupless so participants should carry their own cup or bottle. Race entries require a property waiver for entry. Chip timing is used and official rankings use gun time. Pacers are permitted under specified rules. Overall awards include top finishers and masters categories, and a youth mile is offered as an untimed family-friendly option.
