Isle du Bois Trail Run
The Isle du Bois Trail Run takes place at the Isle du Bois Unit of Lake Ray Roberts in Pilot Point, Texas, on the east side of the lake. The course is a mix of well groomed single track with some technical sections featuring roots and rocks. Each full loop has under 1,000 feet of elevation gain.
Distances offered:
- 4M run, one loop (≈4 miles)
- 10M run, one loop (≈11 miles)
- 20M run, two loops (≈11 miles each)
- 50K run, three loops (≈11 miles each)
This is a cupless race; participants must carry a hydration device such as a water bottle or hydration bladder. Aid stations provide water, endurance drink, and typical aid station food; distances between aid stations range from 1.5 to 4 miles. Organizers sell a reusable collapsible cup at packet pickup for $5.
Drop bags are allowed for 20M and 50K at the start/finish area and are left at the runner’s risk; the event will not mail or deliver left items. Pacers are not allowed. If significant rain occurs, the course may be moved to the Greenbelt trail within the same state park and runners will be notified by email and social media.
Awards and apparel: overall and masters prizes are awarded in specified races, all finishers receive a medal for their distance, and registered participants receive a race shirt in the size indicated at registration. Park access requires a valid day pass, camping pass, or annual Texas State Park Pass. Visit the organization's website for the most recent information.
