It is a fast course, but sometimes heat is a factor. Even in January, temperatures can be in the 60's or 70's and very humid. Altitude is no problem-the city is only 50 feet above sea level. The course is an interesting tour of Houston. Runners move through concrete canyons and through old-growth pine and live oak forests, shopping centers and neighborhoods from modest to wealthy.
Routes are lined with throngs of cheering fans.
The event attracts world-class runners from countries all over the globe, as well as thousands of local runners. Usually about 5,000 compete, and an equal number of volunteers support them. Some man the Hoopla stations,and others provide hydration and refreshment as well as first aid along the way. Others man the medical station at the start finish line. That's where the marathon fantasy comes true for those of us who cannot run the race.
