Fast. Flat. January.

Know the course before you race it.
Terrain
Flat loop through downtown Houston and the Museum District. One of the most flat marathons in the US. Ideal for BQ attempts.
Conditions
January in Houston: 38–58°F at the start. Can be humid even when cool. Occasionally warm — Houston winters are unpredictable.
Aid Stations
Gatorade Endurance and water every mile from mile 3. Gels at miles 10, 15, and 20.
Key Challenge
The flat course and January weather create overconfidence — athletes push too fast in the first 10 miles and run out of glycogen in the flat, featureless second half.
