Isle Du Bois Trail Race

The race will be held at the Lake Ray Roberts - Isle du Bois Unit in Pilot Point, Texas on December 7, 2019. The DORBA Trail at Ray Roberts Lake State Park is just 30 minutes north of Denton on beautiful Lake Ray Roberts. This wooded trail is a mix of fast, flat single track along with some of the most challenging rocky sections in the region.

As with all of our trail races, this is a cupless event and runners will need to provide their own hydration system (handheld, hydration pack etc.). Aid stations will be stocked with a variety of sweet and salty snacks as well as Hammer Nutrition products for electrolytes and some gels.
