About the Brazos Bend 100 Mile

The 100M is separately entered and scored during the December Brazos Bend event. Its flat park loops, qualifying status and cash awards create a clear identity from the 100K and shorter races.

Course

The looped course crosses flat crushed rock, shaded hiking trail and smooth horse trail in Brazos Bend State Park. Lack of climbing shifts the challenge toward pace discipline and repetition.

Race-day weather

December near Houston can be cool and dry or warm, humid and wet. Rain may soften trails, while exposed sections and temperature swings still matter across 32 hours.
