Comfortable temps, warming through the race

Mild 52°F temps at gun time mean comfortable early miles without overheating risk. Temperatures rising to 63°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 75% is worth noting for effort level, especially in later miles.

Race Info

The 100 Mile at Brazos Bend State Park is run as repeated loops of roughly 16.7 miles that start and finish at the Elm Lake pavilion. The course is almost entirely flat, with one 10-foot rise, and mixes crushed rock, shaded hiking trail and smooth horse trail. It is a Western States 100 qualifying race for runners who finish in under 32 hours, and the park is known for its birds and American alligators.
