Flat and fast. Under dry conditions, most runners will choose road shoes on these wide, smooth pathways with minimal debris and good footing. Some sections can become muddy when wet and we will avoid any trail sections that become too messy under wet conditions. 2025 courses to be finalized (the course is always subject to minor changes).

Brazos Bend 100 will have a total of three fully stocked aid stations on the course in addition to a number of unmanned water stations.

ALL runners must carry a form of hydration (bottle, flask, bladder, etc.). There will be NO cups at the aid stations.

• 40 Acre Lake Unmanned Water
• Nature Center Aid Station (no drop bags)
• Sawmill Aid Station
• Elm Lake Start/Finish Main Aid Station (personal area access)

Several drinkable water spouts exist along the trail to the Sawmill Aid Station, and are options for runners to refill.

Runners, family, friends, and crew are encouraged to set up their own hang-out support area around the large grass area at the start/finish for extended rest periods, personal gear, and preferences for food and hydration. It is common for clubs, teams, and families to have a tent set up to enjoy the day. There is no camping at Elm Lake Pavilion. Runners can have access to their personal gear between loops.
