The three races of the Houston Marathon Warm-up Series are the Houston Half Marathon, the HMSA Classical 25K and the Finish Line Sports Sugar Land 30K. These races have been managed by the Houston Striders, the Houston Masters Sports Association and Finish Line Sports, respectively, since the inception of the warm-up series. The purpose of the warm-up series joint registration is to reward those runners who commit to run all three races in the series with a reduced cost for the series. This also allows the runners to plan their progressive training in preparation for the Chevron Houston Marathon. Finally, it allows the race managers some flexibility in their planning for their respective races.
