When is there a marathon in Houston? How can i train for it?

I know there is a Houston Chevrolet marathon coming up in january but that is too close and i have not trained yet. What are some other 2008 Houston Marathon dates? How could i train for them? I play soccer so i usually run 6 to 8 miles every gamej, and i'm aware a marathon is much longer but how long would i need to train for it?|||The Houston Chevron Marathon is in mid-January. Its the only major marathon on the calendar for Houston. There is a marathon in Kingwood on Jan. 1st which is pretty small and intended for 50-staters. There are other Texas marathons in February and March. You should allow 90-120 days to train for your first one at a minimum, depends on fitness level. Lots of training resources out there: running clubs, running stores, websites, magazines.|||check out "halhigdon.com" for training schedules for 1st time marathoners and expereienced ones too.
